The Spring Tree Health Checklist Every Homeowner Should Follow

Mulch is one of the best things you can give your trees — but only when it’s applied correctly. When mulch is used the wrong way, it can trap moisture, attract pests, weaken the trunk, and even kill a healthy tree over time. Here are the most common mulching mistakes we see in Winnipeg yards, and how to fix them so your trees stay strong and healthy. 1. “Volcano Mulching” Around the Trunk A mulch “volcano” is when mulch is piled high against the trunk. It looks tidy, but it causes: Bark rot Moisture buildup Pest and fungus problems Girdling roots Trunk decay Correct method: Keep mulch 3–6 inches away from the trunk. The base of the tree should always be visible. 2. Using Too Much Mulch A thick layer of mulch can: Suffocate roots Prevent oxygen from reaching the soil Encourage shallow, weak root growth Trap too much moisture Correct method: Keep mulch 2–4 inches deep , spread evenly. 3. Using the Wrong Type of Mulch Avoid: Dyed mulch Mulch with unknown fillers Mulch that smells sour or moldy These can introduce toxins or pests into your soil. Correct method: Use clean, natural, organic mulch that breaks down slowly and enriches the soil. 4. Mulching Too Close to the Roots Mulch should protect the root zone — not smother it. If mulch is piled directly over exposed roots, it can: Trap moisture Encourage fungal growth Cause roots to rot Correct method: Spread mulch in a wide, even ring , ideally reaching the tree’s drip line. 5. Not Refreshing Mulch Properly Old mulch can compact over time, preventing water and air from reaching the soil. Correct method: Each spring: Rake and fluff old mulch Remove excess buildup Add a thin fresh layer if needed Why Proper Mulching Matters Correct mulching: Protects roots Regulates soil temperature Reduces weeds Conserves moisture Improves soil health Helps young trees establish faster Done wrong, it can quietly damage your tree for years before symptoms appear.
