What is Deep Root Fertilization and Why Does it Matter in the Summer?

Deep root fertilization isn’t your typical sprinkle-and-hope approach. Unlike standard surface fertilizing, this method uses special equipment to inject a custom nutrient blend directly into the soil around your tree’s root zone, where it can actually do its job.

In Minnesota, where soil can be compacted and nutrient-poor, this can make a real difference. It’s especially helpful for urban and suburban trees competing with lawns, sidewalks, and compacted yards.

How is Deep Root Fertilization different from regular fertilization methods?

When you spread fertilizer on your lawn, a lot of it never reaches your trees’ roots. Turf grass, hard soil, and rainfall runoff can block nutrients or wash them away. Deep root fertilization bypasses all that by delivering nutrients exactly where roots absorb them best, 8-12 inches below the surface.

This feeds the tree directly, improves soil structure, encourages stronger root growth, and helps your trees handle stress better. 

Why Mid-Summer Is the Ideal Time

Trees do most of their heavy lifting in the summer. They’re fully leafed out, using energy to grow, and fighting off pests and diseases. Mid-summer deep root feeding gives them an extra boost when they need it most.

Here’s why summer is the best time to do deep root fertilization:

  • Boosts root and canopy growth: Encourages strong roots and fuller, greener foliage.

  • Helps trees handle drought: Well-fed roots hold moisture better during dry spells.

  • Strengthens natural defenses: Healthy trees are more resilient to pests and common Minnesota diseases.

By fertilizing now, you’re not only helping your trees recover from early summer stress, but also setting them up for a healthy fall and a stronger start next spring.

Who Benefits From Deep Root Fertilization?

Deep root fertilization isn’t just for struggling trees. Instead, it’s a smart investment for a variety of situations. Here’s when it really pays off:

Mature trees showing signs of stress: 

Older trees often struggle with compacted soil and nutrient deficiencies after decades in the same spot. If you notice thinning canopies, smaller leaves, or dead branches, deep root feeding can help restore vitality and extend their lifespan.

Trees in high-traffic yards: 

In the Twin Cities suburbs, yards see plenty of foot traffic, mowers, and soil compaction. Trees in compacted urban soil can’t absorb nutrients well. Deep root injections get through the hard-packed earth to feed roots directly.

Newly planted trees: 

Young trees need all the help they can get to establish healthy root systems. A deep root feeding in the first few years gives them the boost they need to adapt, especially in Minnesota’s unpredictable weather.

Ornamental trees: 

If you have beautiful shade trees, flowering ornamentals, or statement evergreens that add value and curb appeal to your home, deep root fertilization keeps them healthy, lush, and resistant to pests and diseases. 

No matter your yard or tree type, deep root fertilization is about giving your trees what they can’t always get from the surface, and Birch Tree Care is here to help you do it right.

Summer Tree Pests to Watch Out For in Minnesota

How Birch Tree Care Can Help You Stay Ahead of Them

Minnesota summers were made for patio dinners, lakeside campfires, and the deep shade of mature trees. Unfortunately, warm weather also invites a lineup of insects and diseases that can turn those shade-makers into eyesores—or even hazards. 

At Birch Tree Care, we believe in open, honest communication and proactive solutions. Below you’ll find the key pests and pathogens we’re watching this season, what they look like, and why timely, professional care matters.

1. Japanese Beetle

Why it matters: This shiny invader feasts on more than 300 plant species, skeletonizing leaves and stressing shrubs, trees, and even turfgrass when its grubs chew roots. 

Prime time: Adults emerge in late June and peak through August, swarming favored plants like Lindens, Roses, and Birches. 

What to spot:

  • Metallic green and copper adults clustering on foliage

  • Lace-like “windows” in leaves

  • Patches of browning lawn that peel up like loose carpet (grub feeding)

Birch Tree Care approach: Monitoring starts the moment beetles appear. We can recommend low-impact strategies or, when needed, targeted treatments—always mindful of pollinators and your landscape goals.

2. Oak Wilt

Why it matters: A fast-moving fungal disease that can kill Red Oaks in weeks and is expanding—now confirmed in 33 Minnesota counties. 

Prime time: Sap beetles spread the fungus April – July, making summer wounds (like storm damage or pruning cuts) especially risky.

What to spot:

  • Sudden wilting and browning from the top of the crown downward

  • Leaves with green centers and brown edges littering the ground

  • Rapid die-off of Red Oaks; slower decline in White and Bur Oaks

Birch Tree Care approach: We assess, confirm diagnosis, and develop integrated plans—often a mix of root-zone barriers, strategic removal, and fungistatic injections—to protect the healthy oaks that make the Twin Cities canopy special.

3. Dutch Elm Disease

Why it matters: Still the leading killer of Elms statewide; once infected, susceptible trees may die the same season. Minnesota Department of Agriculture

Prime time: Bark beetles carry spores anytime elms are actively growing, but drought-stressed trees are hit hardest.

What to spot:

  • “Flagging” — single branches whose leaves turn yellow then brown

  • Brown streaking in sapwood under the bark

  • Progressive crown thinning if infection spreads through root grafts

Birch Tree Care approach: Early detection is critical. We provide laboratory confirmation, sanitation pruning, and protective fungicide programs for prize elms.

4. Bur Oak Blight (BOB)

Why it matters: A relatively new fungal leaf disease causing leaf browning and drop in late summer and early fall—especially after rainy springs. MN DNR

Prime time: Symptoms ramp up from August onward.

What to spot:

  • Wedge-shaped brown lesions starting at leaf tips

  • Vein browning and black spotting

  • Repeated heavy defoliation that leaves trees vulnerable to other pests

Birch Tree Care approach: We evaluate severity, boost tree vigor, and—when justified—apply fungicides during the narrow spring window when they’re effective.

5. Two-Lined Chestnut Borer

Why it matters: Native beetles whose larvae tunnel beneath bark, attacking drought- or BOB-stressed Oaks and often finishing them off within two to three years.

Prime time: Adult beetles fly June–July; larval feeding continues through summer.

What to spot:

  • D-shaped exit holes on the trunk

  • Patchy branch dieback starting in the upper canopy

  • Sprouts (“epicormic shoots”) on the trunk as trees struggle to survive

Birch Tree Care approach: By reducing stress factors and timing preventive trunk injections, we give embattled Oaks a fighting chance.

6. Magnolia Scale

Why it matters: One of the largest soft scales; each ½-inch, dome-shaped insect sucks sap and coats branches in sticky honeydew that invites sooty mold. Populations surge from late July through August. 

Prime time: Late summer crawler stage is the sweet spot for control.

What to spot:

  • Pinkish-orange to brown bumps along twigs

  • Sticky, shiny residue under the tree

  • Wasps, ants or bees attracted to the sugary honeydew

Birch Tree Care approach: We time horticultural oils or systemic treatments precisely to crawler emergence—keeping your Magnolias picture-perfect for spring bloom.

Summer Tree Care Plan for Minnesota Homeowners

Summer in Minnesota is no joke. You have the scorching sun one day and sideways rain the next. If you’ve lived here long enough, you know our trees take a beating from more than just the heat. They face high winds, sudden droughts, invasive pests, and nutrient-poor soil, all in a matter of weeks. 

For homeowners across the Twin Cities and nearby spots like Maple Grove, Minnetonka, Eden Prairie, and Wayzata, staying on top of tree care in summer is key.

Instead of a generic to-do list, we’re breaking it down month by month to help you stay proactive without getting overwhelmed. Plus, we’ll show you where Birch Tree Care can step in to help when you need extra hands (or expertise). 

June tree care schedule (Start prepping for the season)

1. Deep watering: Don’t rely on thunderstorms to get the job done. Your trees need deep watering (10 gallons per inch of trunk diameter) once or twice a week to build drought resistance. Shallow, frequent watering actually weakens roots.

2. Smart mulching: Mulch is your tree’s best friend if done right. A fresh 2-4 inch layer helps regulate soil temperature and moisture, but keep it a few inches away from the trunk to avoid rot.

3. Missed fertilization? There’s still time: Early spring is ideal, but many Minnesota trees can still benefit from summer fertilization. Our fertilization services are customized to your local soil conditions.

4. Early pest check: Bronze birch borers and aphids love early summer. Yellowing leaves or sudden leaf drop are early signs. Our arborists can spot trouble before it spreads. 

July plant treatment schedule (maintain and monitor your plants)

1. Stay on a watering schedule: The heat is on. Test your soil about 6 inches down. If it’s dry, it’s time to water. Consider using soaker hoses or drip systems for even moisture.

2. Know your summer pests: Keep an eye out for Japanese beetles, lace bugs, and spider mites. Beetles chew leaves; mites leave tiny webs. Need backup? We’ve got your pest control covered.

3. Prune: Don’t go wild with pruning in July. Your tree is in full growth mode. But broken or diseased branches? Those can go. Our tree trimming experts know how to make clean, healthy cuts.

4. Storm-proofing: With storms rolling in, now’s the time to check for limbs near power lines, dead wood, or weak branch unions. We offer structural assessments and cabling services, as well as emergency storm damage assistance to keep things safe. 

August tree care schedule (Protect your trees)

1. Don’t let up on water: August tends to be dry in the Twin Cities region. Continue watering consistently to reduce drought stress. Look out for leaves curling or dropping early.

2. Watch for late-season stress: Heat, pests, and compacted soil all take their toll. If your tree looks “off” (sparse canopy, premature colour change), it’s time for a health check.

3. Plan for fall: Fall fertilization, root collar excavation, and dormant pruning season are just around the corner. Book an inspection now while our schedule still has room.

4. Spot issues early: Whether you’re in Excelsior, Plymouth, or Hamel, don’t let small signs turn into big problems. Our team at Birch Tree Care offers custom care plans to support your trees year-round.

Spider Mite Treatment in Minnesota

At Birch Tree Care, we understand how pests can silently threaten the health and longevity of trees across Minnesota—and spider mites are a common, yet often overlooked, problem. These microscopic pests can cause significant damage, especially during the hot, dry summer months typical in parts of the Twin Cities region. Dry and dusty conditions further increase the risk of Spider Mite infestations.

If your trees are showing signs of discoloration, stippling, yellowing, or general decline in foliage, our Certified Arborists can help identify and treat spider mite infestations with effective, science-based solutions. We offer a range of treatment options—including chemical, biological, and manual approaches—tailored to your landscape’s specific needs.

What Are Spider Mites?

Spider Mites are tiny arachnids that feed on plant cells by piercing leaf surfaces and extracting their contents. This feeding behavior causes visible damage, including stippling and bronzing of leaves. Although they’re barely visible to the naked eye, their presence becomes obvious once damage appears.

Spider Mites thrive in warm, dry weather and can infest a wide variety of plants, including trees, shrubs, vegetables (like cucurbits, beans, and tomatoes), and other outdoor plants.

Common signs of spider mite damage include:

  • Yellow or bronze speckling on leaves (stippling)

  • Fine webbing on branches and especially the undersides of leaves

  • Visible colonies or feeding damage

  • Leaf drop or thinning foliage

  • General tree stress or a decline in overall appearance

In Minnesota, spider mites are most active from late spring through early fall, particularly during periods of drought or high heat.

They can affect both deciduous and evergreen trees, with common targets including:

  • Spruce (especially Colorado Blue Spruce)

  • Arborvitae

  • Honeylocust

  • Maples

  • Elms

  • Ash trees

Are Spider Mites Dangerous to Trees?

Yes—while a single infestation may not kill a healthy tree outright, repeated or severe infestations can lead to long-term damage. Spider Mites can stress trees, reduce vigor, and make them more susceptible to other pests and diseases. Even species that are typically resistant are not immune.

When identified early, Spider Mite problems are manageable. Without intervention, however, infestations can rapidly spread across your trees, shrubs, garden, and other surrounding vegetation.

Spider Mite Treatment and Control in Minnesota

At Birch Tree Care, we take an integrated, environmentally responsible approach to pest management. Our Spider Mite treatments are effective, science-backed, and tailored to each client’s landscape.

Because Spider Mites reproduce quickly, repeat treatments are often necessary. We use organic options—like neem oil, horticultural oil, and insecticidal soap—whenever possible.

Our Spider Mite control services include:

1. Accurate Diagnosis

Spider Mite damage can resemble symptoms of drought stress or nutrient deficiency. Our ISA Certified Arborists conduct thorough inspections to confirm the presence of mites and assess the extent of the damage.

During diagnosis, we also check for Spider Mite eggs and immature stages—such as larvae and nymphs—which are essential to identify for complete and effective management.

2. Treatment Options

Depending on the infestation severity, we may recommend:

  • Horticultural oils or insecticidal soaps: These treatments reduce feeding activity and population levels while sparing beneficial insects.

  • Miticides: For persistent outbreaks, miticides may be used. These are applied by licensed professionals to avoid unintended side effects. Some insecticides can trigger mite population spikes if not applied properly.

  • Rubbing alcohol: A diluted alcohol solution can help eliminate mites when sprayed directly onto affected areas. Test a small section first to avoid plant injury.

  • Cultural adjustments: Improving watering practices and overall tree health helps reduce stress and support recovery. Comprehensive care ensures all affected areas are addressed.

3. Preventative Care

We emphasize prevention to reduce the chance of future outbreaks. Healthy trees are more resilient to Spider Mite damage. 

Our preventative services include:

  • Deep root fertilization

  • Proper mulching and consistent watering practices

  • Seasonal inspections and monitoring

  • Regular washing of foliage to remove dust buildup

  • Monitoring outdoor plants during dry spells

  • Maintaining indoor humidity levels to prevent infestations on houseplants

Why early spring is the best time for tree fertilization in the Twin Cities

Minnesota winters are brutal. Not just on us, but on our trees too. After months of snow, ice, and freezing temperatures, the trees around Minneapolis and St. Paul need some serious TLC.

Birch Tree Care has been around for over a decade now, with arborists and technicians working in yards across Eden Prairie, Maple Grove, Wayzata, and pretty much every neighborhood in between. One thing they’ve learned? Most homeowners don't think about fertilizing their trees until it's already summer, and by then, they've missed the perfect window.

Why do trees need fertilizer after winter in Minnesota?

Think about it. Your trees have just endured months of dormancy with barely any nutrients. Their root systems are weak, and they're desperately trying to push out new growth. It's like trying to run a marathon after fasting for three months.

When we fertilize in early spring, we're essentially serving up a nourishing breakfast right when trees are waking up. Our experienced technicians have seen the difference firsthand. Trees that get that early boost develop fuller canopies, stronger branch structures, and just look healthier overall.

Best time to fertilize trees in Twin Cities: the early spring

There's something special about Minnesota soil in early spring. It's got that ideal moisture balance, not waterlogged from snowmelt anymore but not dried out from summer heat either. The cool, damp conditions create ideal circumstances for nutrient absorption.

Our tree and shrub fertilization services can help make a huge difference for your landscape. Our technician was at a property in Minnetonka last year where the homeowner had always fertilized in late June. He convinced them to switch to early April, and the difference in their maple trees was night and day. The roots had time to soak up everything before the summer stress kicked in. 

How spring tree fertilization prevents summer storm damage

Let's be real, summer in the Twin Cities brings its own challenges. We get those sweltering weeks, random storms that tear through neighborhoods, and the occasional drought spell that leaves everything parched.

Trees that get a good spring feeding handle all this so much better. It's like the difference between facing a challenge well-rested versus tackling it exhausted. We've tracked the storm response of fertilized versus unfertilized trees across Plymouth and Excelsior properties, and the resilience difference is remarkable.

Which tree fertilizer is best for Minnesota trees?

Many homeowners aren't aware that different tree species have unique nutritional needs. It's actually quite common to pick up a general-purpose fertilizer at the garden center, thinking it will work for everything in your yard. What we've learned over the years, though, is that your mature oak thrives with a completely different nutrient blend than your young maple or your struggling crabapple.

Last spring, we worked with a family in Wayzata who couldn't figure out why their birch trees were yellowing despite regular fertilization. Turns out they needed an entirely different nutrient ratio. Within weeks of getting the right blend, those trees transformed.

Professional tree care services in Twin Cities

Spring fertilization isn't just a one-and-done task, but rather an opportunity to set up your trees for year-round success. When we visit properties in Hamel or Mound, we’re not just thinking about that day's application. We’re looking at the soil composition, checking for signs of stress or disease, and helping create a full-year plan.

Most of our clients are surprised by how much healthier their entire landscape becomes when we address tree nutrition properly from the start of the growing season.

How to schedule tree fertilization in Eden Prairie, Wayzata and the neighboring areas

Your trees are probably the oldest living things on your property. They've likely been there longer than you have, and with the right care, they'll be there long after. Don't let another spring go by without giving them what they need.

Whether you're in the heart of Minneapolis or out in Eden Prairie, our certified arborists are ready to help your trees thrive this year. Let's not just keep your trees alive, but rather, help them flourish.

Spotting and Treating Root Rot

Spring in Minnesota brings welcome warmth and new growth, but it also brings a hidden threat to your trees…root rot. Thanks to heavy rains, melting snow, and poorly drained soil, root rot becomes a common problem this time of year. Left untreated, it can lead to declining health or even the death of your trees.

In this guide, we’ll walk you through how to spot the signs of root rot, why soggy soil plays a major role, and what steps you can take to prevent and treat it effectively, whether you live in the heart of the Twin Cities or surrounding communities like Maple Grove, Eden Prairie, Minnetonka, and so forth.

What is root rot?

Root rot is a fungal disease that affects the roots of trees and plants, causing them to decay and die. It’s typically caused by overwatering or poor drainage, creating the perfect environment for fungi like Phytophthora to thrive. In Minnesota, the frequent spring thaw combined with saturated soil can be a recipe for trouble, especially in low-lying areas and properties with clay-heavy soils in places like Plymouth and Wayzata.

How can you spot root rot in your trees?

Because root rot happens below ground, it can be tricky to catch early. But here are some above-ground signs to look for:

  • Yellowing or wilting leaves

  • Stunted growth or sudden dieback

  • Soft, mushy roots (if exposed)

  • Cankers or discoloration near the base of the tree

  • A thinning or uneven canopy

If you notice any of these signs, it’s time to take a closer look, or better yet, call a certified arborist to inspect your tree. Our tree inspection services can help diagnose the issue early. We proudly serve residents across Minnetonka, Eden Prairie, and other Twin Cities metro areas.

Why is soggy soil a problem for your trees roots?

Minnesota’s spring moisture can linger, especially in compacted or clay-heavy soils. When water can’t drain properly, oxygen can’t reach the roots. This lack of oxygen stresses the tree and allows fungi to take hold.

Improper grading, poor landscape design, or simply heavy rainfall can all contribute to soggy soil. Even healthy trees can fall victim if the conditions are right. This is something we often see in neighborhoods across Excelsior, Mound, and Maple Grove.

How can homeowners improve drainage?

Preventing root rot starts with better drainage. Here are a few ways you can protect your trees:

  • Aerate the soil to improve water absorption and root oxygenation

  • Install drainage systems such as French drains or dry wells

  • Avoid overwatering and adjust irrigation based on rainfall

  • Mulch carefully – keep mulch away from the base of the tree to prevent excess moisture retention

  • Regrade your landscape if necessary to promote runoff

If your tree is already showing symptoms, don’t wait. Root rot can progress quickly, especially during the wet spring season.

How Birch Tree Care can help

At Birch Tree Care, we’re no strangers to Minnesota’s (or surrounding areas) tricky spring conditions. Our certified arborists can assess your tree’s health, test for root rot, and offer effective solutions. These might include:

  • Soil treatments to improve drainage and suppress fungal growth

  • Root collar excavations to expose and treat infected areas

  • Selective pruning to remove diseased limbs and reduce tree stress

  • Ongoing tree health care plans to build long-term resilience

We’ll also help you determine if removal is necessary in severe cases. Our tree removal services are handled with safety and care, always putting your property first. 

Root rot is preventable, but only if caught early. By learning the signs and improving your property’s drainage, you can keep your trees thriving through spring and beyond. And if you’re not sure where to start,  our team is just a call away. Let us help you protect your landscape and restore your peace of mind this season.

7 Critical Signs Your Tree Needs Deep Root Fertilization in Minnesota

Why Tree Health Matters in Minnesota

Minnesota’s diverse climate and soil conditions present unique challenges for tree health. From frigid winters and heavy snowfalls to compacted urban soils, trees often struggle to access the nutrients they need to thrive. At Birch Tree Care, we know how important it is to protect your trees from these environmental stressors through tree service and fertilization. One of the best ways to do this is through deep root fertilization, a specialized process that delivers essential nutrients directly to your tree’s root zone.

If you've noticed thinning leaves, slower growth, or weak branches, your tree may be calling out for help. Let’s explore the signs that your trees might need deep root fertilization – and why this treatment is especially critical for Minnesota landscapes.

What is Deep Root Fertilization?

Deep root fertilization involves injecting a nutrient-rich solution directly into the soil around a tree’s root zone, typically 6–12 inches below the surface. Unlike surface fertilizing, which often gets absorbed by grass or washes away, this method ensures nutrients reach the roots where they're needed most.

Our experts at Birch Tree Care use a carefully balanced formula that replenishes depleted soils, encouraging strong growth and resilience – a must in Minnesota’s nutrient-poor and often compacted soils.

Sign 1: Sparse or Discolored Leaves

One of the earliest signs of nutrient deficiency is leaf discoloration. If you notice your tree’s leaves turning pale green or yellow (a condition known as chlorosis), it might be due to a lack of iron, manganese, or other essential micronutrients.

Why This Happens in Minnesota:

  • Many Minnesota soils, especially in urban areas like the Twin Cities, have high pH levels, which limit nutrient availability.

  • Chlorosis is particularly common in Oak, Maple, and Birch trees – species we frequently care for at Birch Tree Care.

Deep root fertilization helps by providing nutrients directly to the roots, giving leaves back their vibrant green color.

Sign 1: Sparse or Discolored Leaves

Have you noticed that your tree isn’t growing as quickly as it used to? Stunted growth and thinning canopies are often linked to poor nutrient availability. Trees need a steady supply of nitrogen, phosphorus, and potassium to grow strong and healthy.

Minnesota-Specific Factors:

  • Long, cold winters shorten the growing season.

  • Compacted soil, common in urban developments, restricts root growth and nutrient uptake.

Regular deep root fertilization ensures that your trees have access to these critical nutrients, even in challenging environments.


Sign 3: Premature Leaf Drop

Minnesota trees naturally drop their leaves in the fall, but if you’re seeing early leaf loss in summer, it could signal a nutrient deficiency or environmental stress.

What Causes This:

  • Drought stress during hot summers.

  • Nutrient deficiencies that weaken the tree’s ability to hold leaves.

  • Compacted soil prevents water and nutrient absorption.

Deep root fertilization restores balance, helping trees retain their foliage longer.

Sign 4: Weak Branches or Dieback

Weak, brittle branches or dead limbs (known as dieback) can indicate a lack of essential nutrients. In Minnesota, heavy snow and ice can worsen the problem, causing weakened limbs to break.

Key Causes:

  • Insufficient potassium, which supports structural integrity.

  • Repeated freeze-thaw cycles that stress tree tissues.

A professional deep root fertilization treatment provides the nutrients necessary to strengthen branches and reduce the risk of damage.

Sign 5: Increased Pest and Disease Vulnerability

Nutrient-deficient trees are more susceptible to pests like emerald ash borers and diseases like oak wilt – both major concerns here in Minnesota.

How Fertilization Helps:

  • A well-nourished tree produces more defensive chemicals to fight pests.

  • Healthy growth patterns reduce entry points for diseases.

Birch Tree Care’s deep root fertilization service enhances your tree’s natural defenses, keeping pests and pathogens at bay.

The Impact of Minnesota’s Unique Climate on Tree Health

Minnesota's freeze-thaw cycles, compacted urban soils, and short growing seasons create significant challenges for tree health. Without adequate nutrients, trees may struggle to recover from seasonal stress and continue growing.

Unique Climate Factors:

  • Freeze-Thaw Cycles: Repeated freezing and thawing can damage root systems and make nutrients less available.

  • Compacted Urban Soils: In cities like Minneapolis and St. Paul, heavily compacted soil limits water and nutrient absorption.

  • Short Growing Season: Trees have a shorter window to gather resources, making timely fertilization critical.

When is the Best Time for Deep Root Fertilization in Minnesota?

Timing is crucial when it comes to tree fertilization. In Minnesota, the most effective periods for deep root fertilization are early spring and late fall.

Why These Seasons Matter:

  • Spring: Fertilizing before the growing season gives trees the nutrients they need to produce new growth.

  • Fall: Late-season applications help strengthen roots for winter survival.

Summer fertilization is less common, as heat and drought can stress trees further.

Long-Term Benefits of Deep Root Fertilization

Investing in regular deep root fertilization provides long-lasting benefits that go beyond immediate improvements in leaf color or growth.

Key Advantages:

  • Stronger Roots: Enhanced nutrient availability promotes deeper, more resilient root systems.

  • Improved Growth: Trees grow faster and develop fuller canopies when they receive the right nutrients.

  • Pest and Disease Resistance: Healthy, well-fed trees can better defend against Minnesota-specific threats like Emerald Ash Borer and Oak Wilt.

  • Increased Lifespan: Properly fertilized trees live longer, healthier lives, adding value to your property.

Frequently Asked Questions (FAQs)

How do I know if my tree needs fertilization?

Look for signs like discolored leaves, stunted growth, early leaf drop, or weak branches. If you’re unsure, our arborists can assess your tree’s condition.

Can fertilization save a dying tree?

In some cases, yes. If nutrient deficiency is the cause of the decline, deep root fertilization can restore health. However, trees affected by severe disease or structural damage may not recover.

How often should I fertilize my trees?

Most Minnesota trees benefit from annual fertilization, though specific timing may vary based on soil conditions and tree species.

Is deep root fertilization safe for the environment?

Yes. We use eco-friendly, slow-release formulas that nourish your trees without harming surrounding plants or groundwater.

How does Minnesota’s climate affect fertilization timing?

The state’s short growing season and harsh winters make spring and fall the best times to fertilize. Our team can help you find the ideal window for your trees.

Protect Your Minnesota Landscape with DeerPro

Minnesota homeowners and property managers face a common challenge: maintaining a beautiful, thriving landscape while keeping deer at bay. As temperatures drop and natural food sources become scarce, deer often turn to residential properties, feeding on trees, shrubs, and plants. This not only damages the aesthetic appeal of your landscape but can also lead to long-term health issues for your plants.

At Birch Tree Care, we understand the frustration of investing in your landscape only to see it ravaged by deer. Our mission is to provide competitive, honest, and professional solutions that protect your property. One of the most effective ways to prevent deer damage is through DeerPro, a professional-grade repellent designed for long-lasting protection.

Understanding Deer Damage: Why Your Landscape is at Risk

Deer are opportunistic feeders, and when food sources become limited, they turn to the trees, shrubs, and perennials in your yard. Certain plant species are especially vulnerable, and repeated deer browsing can lead to stunted growth, disease, and even plant death.

Here are some common ways deer can damage your landscape:

1. Bark Stripping on Trees

During the fall and winter months, deer rely on tree bark as a food source. They use their teeth to strip bark from trunks and branches, which can expose trees to pests, fungal infections, and decay. This damage is especially harmful to young trees that have not yet developed strong, protective bark.

2. Feeding on Shrubs and Perennials

Deer prefer tender, nutritious foliage, making ornamental shrubs and perennials a prime target. If you have invested in landscaping with species like arborvitae, hostas, or tulips, you may notice them being eaten down to the stem.

3. Trampling and Soil Disruption

Large deer populations can lead to overgrazing and soil compaction, which can affect the growth of grass, flowers, and other plantings. Their hooves create stress on delicate root systems, reducing the ability of plants to absorb nutrients.

4. Repeated Damage and Deer Trails

Deer are creatures of habit, meaning once they identify a reliable food source, they will return repeatedly. This can result in permanent damage and even attract more deer to your property.

The Solution: How DeerPro Provides Reliable Protection

Many homeowners try DIY solutions like homemade sprays, fencing, or deer-resistant plantings, but these methods often require constant maintenance and are not 100% effective. That’s why professional applications like DeerPro are the best option for long-term, low-maintenance protection.

DeerPro offers two specialized formulas designed to protect your landscape year-round.

DeerPro Winter Protect: Defense Against Harsh Conditions

  • Applied in late fall, this single application lasts all winter

  • Forms a durable, water-resistant coating that prevents deer from feeding on treated plants

  • Reduces the risk of bark stripping and shrub damage during the coldest months

Unlike many store-bought deer repellents that wash away in rain or snow, DeerPro Winter Protect remains effective throughout Minnesota’s harsh winter season.

DeerPro Growing Season: Continuous Protection for Lush Growth

  • Applied in spring and summer, when plants are actively growing

  • Protects new, tender growth on shrubs, trees, and perennials

  • Remains odorless to humans while effectively repelling deer

Because it’s a professionally applied solution, DeerPro provides superior coverage and reliability compared to DIY treatments.

Deer Health

How Does Deer Pro Affect Deer?

Deer Pro is formulated to serve primarily as a deterrent—its ingredients create a scent or taste that deer find unpleasant, prompting them to avoid treated areas. Because it relies on naturally distasteful or repellent components rather than toxic chemicals, it does not harm the deer. Instead, it encourages them to seek alternative feeding grounds, helping minimize damage to plants without endangering wildlife.

Is It Just a Repellent?

Yes. Deer Pro’s main function is to repel deer by making the treated foliage less appealing. It does not contain substances intended to injure or kill deer.

Does It Harm Deer or Impact Their Natural Patterns?

Deer Pro is not harmful to deer when used as directed. It causes minimal disruption to their overall habits beyond discouraging them from browsing in specific areas. The aversion effect typically does not result in significant changes to migration routes, reproductive cycles, or other natural behaviors. Instead, deer simply learn to avoid the spots where Deer Pro has been applied, protecting plants without negatively affecting the health or wellbeing of the animals.

Tips for Keeping Deer Away

While DeerPro is one of the most effective solutions available, there are additional steps you can take to reduce deer activity on your property:

1. Choose Deer-Resistant Plants

Some plants are naturally less appealing to deer. Consider incorporating species such as:

  • Boxwood

  • Daffodils

  • Lavender

  • Yarrow

  • Spruce trees

2. Install Strategic Fencing or Barriers

Physical barriers, such as tall fencing, netting, or motion-activated deterrents, can help reduce deer access to vulnerable areas.

3. Rotate Repellents and Strategies 

If deer become accustomed to a single deterrent, they may adapt over time. Using a combination of DeerPro, fencing, and plant choices can create a multi-layered defense.

4. Keep Your Landscape Well-Maintained

Regular pruning, mulching, and fertilization help trees and shrubs recover from minor deer damage and improve their resilience.
