Spring Tree Care Checklist for Lower Mainland Properties

Spring is nature's renewal season, and it's the perfect time to give your trees the care they need to thrive throughout the year. As certified arborists serving the Lower Mainland, we've developed this comprehensive checklist to help property owners maximize their trees' health and beauty during the critical growing season.

Early Spring Tasks (March - April)

1. Winter Damage Assessment

Begin your spring care routine with a thorough inspection of all trees on your property. Winter weather can cause various types of damage that need immediate attention:

• Broken or hanging branches: Remove immediately to prevent property damage
• Bark damage: Look for splits, cracks, or areas where bark has peeled away
• Root exposure: Check for soil erosion around the base of trees
• Leaning trees: Note any trees that may have shifted during winter storms

2. Dormant Season Pruning

Late winter to early spring (before bud break) is the ideal time for most pruning activities. This timing minimizes stress on trees and reduces the risk of disease transmission:

Priority Pruning Tasks:

• Remove dead, diseased, and damaged wood (3 D's)
• Eliminate crossing and rubbing branches
• Thin dense canopies to improve air circulation
• Raise canopy for clearance from structures and walkways
• Shape young trees for proper structure

3. Soil Assessment and Preparation

Spring is an excellent time to evaluate and improve soil conditions around your trees:

• Test soil pH and nutrient levels - Most trees prefer slightly acidic to neutral soil (pH 6.0-7.0)
• Check for compaction - Use a soil probe or screwdriver to test soil density
• Evaluate drainage - Look for standing water or overly dry areas
• Address compaction issues - Consider aeration or vertical mulching for severely compacted areas

Mid-Spring Tasks (April - May)

4. Fertilization Program

As trees begin active growth, they benefit from proper nutrition. The Lower Mainland's frequent rainfall can leach nutrients from soil, making spring fertilization particularly important:

Fertilization Guidelines:

• Use slow-release fertilizers to provide consistent nutrition throughout the growing season
• Apply fertilizer to the drip line area where feeder roots are most active
• Consider organic options like compost, aged manure, or organic tree fertilizers
• Water thoroughly after application to activate nutrients and prevent root burn

5. Mulching

Proper mulching is one of the most beneficial practices for tree health. Spring application helps retain moisture during the growing season and suppresses weeds:

Mulching Best Practices:

• Apply 2-4 inches of organic mulch (wood chips, bark, or compost)
• Keep mulch 6 inches away from the trunk to prevent pest and disease issues
• Extend mulch to the drip line or as far as practical
• Refresh annually as organic mulch decomposes and enriches the soil

6. Irrigation System Setup

While the Lower Mainland receives significant rainfall, summer dry periods can stress trees. Establishing proper irrigation early in the season ensures consistent moisture:

• Install drip irrigation or soaker hoses for efficient water delivery
• Position emitters at the drip line where feeder roots are concentrated
• Test system operation and adjust for proper coverage
• Consider timer systems for consistent watering schedules

Late Spring Tasks (May - June)

7. Pest and Disease Monitoring

As temperatures warm and new growth emerges, many pests and diseases become active. Early detection is key to effective management:

Common Spring Issues to Watch For:

• Aphids: Small, soft-bodied insects that cluster on new growth
• Scale insects: Small, waxy bumps on branches and leaves
• Powdery mildew: White, powdery coating on leaves
• Leaf spot diseases: Circular spots or blotches on foliage

8. Young Tree Care

Trees planted within the last 2-3 years require special attention during their establishment period:

• Check and adjust stakes and ties - Remove or loosen if restricting growth
• Maintain consistent moisture - Young trees are more susceptible to drought stress
• Perform structural pruning - Guide development of strong branch architecture
• Monitor for girdling roots - Address circling roots before they become problematic

Conclusion

Following this comprehensive spring care checklist will set your trees up for a healthy, vigorous growing season. Remember that tree care is an investment in your property's beauty, safety, and value. While many tasks can be accomplished by dedicated property owners, don't hesitate to consult with certified arborists for complex issues or when you're unsure about the best approach.

The Lower Mainland's unique climate presents both opportunities and challenges for tree care. By staying proactive with spring maintenance and working with experienced professionals when needed, you can ensure your trees remain healthy, beautiful assets for years to come.
