The Importance of Mulching for Tree Health and How to Do It Right
Trevor Soltys & Paul Kasper
Mulching is one of the simplest yet most effective ways to promote tree health. When done correctly, mulching provides numerous benefits, from moisture retention to weed suppression and soil improvement. However, improper mulching techniques can do more harm than good. In this guide, we’ll explore why mulching is essential for trees and how to do it properly.
The Benefits of Mulching
- Moisture Retention – Mulch acts as a protective barrier, reducing evaporation and helping the soil retain moisture. This is especially beneficial during hot summer months or in dry climates.
- Weed Suppression – A properly applied mulch layer helps prevent weeds from sprouting by blocking sunlight from reaching the soil surface.
- Temperature Regulation – Mulch insulates tree roots, keeping them cooler in summer and warmer in winter, which helps reduce stress on the tree.
- Soil Enrichment – Organic mulches decompose over time, adding nutrients and improving soil structure, which enhances root health and growth.
- Prevention of Soil Compaction – A mulch layer reduces the impact of heavy rains and foot traffic, preventing soil from becoming compacted and restricting root expansion.
- Protection Against Mechanical Damage – Mulching creates a buffer zone that protects the base of the tree from lawnmower and weed trimmer damage.

How to Mulch Properly
While mulching provides many advantages, incorrect application can lead to problems such as root rot, pest issues, and suffocated roots. Follow these steps to ensure proper mulching:
- Choose the Right Mulch – Organic mulches, such as wood chips, bark, pine needles, and shredded leaves, are preferred because they break down naturally, enriching the soil.
- Prepare the Area – Remove any grass, weeds, or debris from the base of the tree before applying mulch.
- Apply the Right Thickness – Spread mulch in a layer about 2–4 inches thick. A thinner layer may not provide enough benefits, while a thicker layer can trap excessive moisture and suffocate roots.
- Avoid Volcano Mulching – One of the most common mistakes is piling mulch against the trunk in a “volcano” shape. This can trap moisture against the bark, leading to rot, disease, and pest infestations. Instead, leave a small gap (about 2–3 inches) around the trunk.
- Extend the Mulch Ring – Ideally, mulch should extend at least to the tree’s drip line (the area directly beneath the outermost branches). For young trees, a 2-3 foot diameter mulch ring is sufficient, while mature trees benefit from a wider coverage.
- Refresh Mulch as Needed – Over time, mulch decomposes and compacts. Check annually and replenish to maintain the recommended thickness while removing any old, compacted layers.
Final Thoughts
Mulching is an easy yet powerful practice that significantly enhances tree health when done correctly. By following proper mulching techniques, you can help your trees thrive while improving the overall aesthetics and health of your landscape. If you’re unsure about the best mulching approach for your trees, consulting a professional arborist can provide valuable guidance tailored to your specific environment and tree species.
๐ณ What Winnipeg Homeowners Should Do Winnipeg winters bring heavy snowfalls that can quietly wreak havoc on your trees. Snow load — the weight of accumulated snow and ice — can bend, crack, or even break limbs, especially on older or structurally weak trees. What Is Snow Load? Snow load refers to the pressure exerted by snow and ice buildup on tree branches. Wet, heavy snow is especially dangerous, and when combined with freezing rain or wind, it can lead to serious damage. Signs of Snow Load Stress: ๐จ๏ธ Limbs bending unnaturally or sagging ๐ชต Cracked or split branches ๐ฒ Sudden limb drop after thaw ๐ง Ice accumulation on branch unions What You Can Do: โ
Gently remove light snow with a broom Always sweep upward — never shake or knock branches. ๐ซ Avoid removing ice manually Let it melt naturally to prevent breakage. ๐งค Inspect trees after storms Look for cracks, splits, or hanging limbs. ๐ Get a winter risk assessment from an arborist. They’ll identify weak points and recommend pruning or cabling if needed. Conclusion: Snow load damage can be subtle — until it’s not. A proactive inspection can prevent costly breakage and keep your trees safe through the season. Contact TreeSolve today to schedule your winter tree check.
๐ณ Why Winter Is a Smart Time for Winnipeg Homeowners Winter may seem like a quiet time for tree care, but it’s actually the best season to assess tree health and safety. With leaves gone and branches exposed, arborists can spot structural issues that are hidden during warmer months. Why Winter Works Best: ๐ชต Better visibility of branch structure Without foliage, cracks, decay, and weak limbs are easier to detect. โ๏ธ Reduced risk of disease transmission Dormant trees are less vulnerable to infections during pruning or inspection. ๐งค Safer working conditions for arborists Frozen ground and bare trees allow for easier access and safer climbing. ๐ธ Off-season availability and pricing Winter assessments often come with more flexible scheduling and potential cost savings. What We Look For: Cracks, cavities, and decay in trunks or limbs Signs of pest damage or fungal growth Weak branch unions and poor structure Risk to nearby structures or walkways Conclusion: A winter tree risk assessment is a proactive step toward protecting your property and ensuring healthy growth in spring. TreeSolve’s certified arborists are ready to help — book your inspection before the snow gets deeper.
๐ณ A Guide for Winnipeg Homeowners Decorating your trees with holiday lights brings festive cheer to your yard — but it can also pose risks if done improperly. From broken branches to fire hazards, it’s important to light up safely. Key Safety Tips: ๐ก Use LED lights designed for outdoor use They’re cooler, more energy-efficient, and reduce fire risk. ๐ฒ Avoid wrapping tightly around branches This can restrict growth and cause breakage, especially in freezing temps. ๐ Inspect cords for damage before installation Frayed wires or cracked plugs can lead to electrical hazards. โ๏ธ Don’t overload circuits or extension cords Spread out your lighting and use grounded outlets. ๐งค Install lights gently and avoid climbing trees Use ladders safely and never staple lights directly into bark. Conclusion: Holiday lights should enhance your landscape — not damage it. If you're unsure about tree safety or need help prepping your yard, TreeSolve is here to help.

๐ณ What Winnipeg Homeowners Need to Know Many homeowners believe that tree care stops when the snow starts falling — but that’s one of the biggest myths in urban forestry. In Winnipeg’s climate, winter is actually a strategic time for certain types of tree maintenance. Main Myths & Truths: โ๏ธ Myth #1: Trees don’t need care in winter Truth: Dormant trees benefit from pruning, inspections, and structural support during this time. โ๏ธ Myth #2: Pruning should only happen in spring Truth: Winter pruning reduces disease risk and improves visibility of branch structure. ๐ Myth #3: Pests aren’t a problem in cold weather Truth: Some pests overwinter in bark or soil — early detection is key. ๐งค Myth #4: Tree services aren’t available in winter Truth: Many arborists offer off-season services, often with better availability and pricing. Conclusion: Winter tree care is not only possible — it’s smart. By tackling key tasks now, you set your trees up for a healthier, safer spring.
