Spring Tree Care Checklist: Protect Your Trees This Season

Your Complete Spring Tree Care Guide

Spring is an exciting time in the landscape, but it is also a critical period for tree health. As trees break dormancy and begin their annual growth cycle, the care you provide now sets the stage for the entire year. Here is your comprehensive spring tree care checklist.

Inspect for Winter Damage

Before anything else, walk your property and examine every tree:

• Look for broken or hanging branches that need removal
• Check for frost cracks on trunks, especially on the south and southwest sides
• Inspect for heaving around the root zone where freeze-thaw cycles may have displaced soil
• Note any trees that appear to be leaning more than they did last fall
• Look for fungal growth on trunks or at the base, which may indicate internal decay

Pruning Best Practices

Spring is ideal for pruning most deciduous trees before full leaf-out:

• Remove dead, damaged, and diseased branches first
• Eliminate crossing or rubbing branches that create wounds
• Maintain proper clearance over walkways, driveways, and structures
• Avoid removing more than 25% of the canopy in a single season
• Do not prune oaks in spring in areas where oak wilt is present
• Avoid pruning elms from April through August to reduce Dutch elm disease risk

Mulching the Right Way

Proper mulching is one of the best things you can do for your trees:

• Apply a 2-4 inch layer of organic mulch around the tree
• Keep mulch 6 inches away from the trunk to prevent moisture buildup and rot
• Extend the mulch ring to the drip line if possible
• Use shredded hardwood bark, wood chips, or composted leaves
• Never create mulch volcanoes piled against the trunk

Watering and Fertilization

• Water deeply and infrequently to encourage deep root growth
• Newly planted trees need 1-2 inches of water per week during the growing season
• Consider a slow-release fertilizer if a soil test shows deficiencies
• Avoid high-nitrogen fertilizers on stressed trees as they push top growth at the expense of roots

Watch for Early Pest Activity

Spring is when many pests emerge:

• Monitor for tent caterpillars building silken tents in branch crotches
• Watch for aphids on new growth, especially on maples and lindens
• Check for scale insects on twigs and branches before leaf-out
• Look for borers by checking for sawdust-like frass at the base of trees

Early detection gives you the best chance of managing pest problems before they cause significant damage. When in doubt, consult with a certified arborist who can recommend targeted treatments, or try our tree health check tool.
