3. Summer Mulching to Retain Moisture and Control Weeds

Mulching around trees is a year-round task, but it’s especially important in summer when high temperatures and evaporation can dry out soil quickly. A well-applied mulch layer helps retain moisture, keeps soil temperatures stable, and minimizes weed growth.

• Applying Mulch Correctly: Spread mulch in a 2-4 inch layer around the base of the tree, extending out to the drip line if possible. Keep the mulch a few inches away from the trunk to prevent moisture buildup and rot, commonly known as “mulch volcanoes.”
• Mulch Materials: Organic mulches like shredded bark, wood chips, or compost are excellent choices as they decompose slowly, enriching the soil over time.
• Benefits of Mulching in Summer: Mulch insulates soil, reduces water loss through evaporation, and limits weed growth, which means less competition for water and nutrients. Mulching also improves the soil’s ability to retain water, reducing the frequency of watering.

Mulching in summer can make a noticeable difference in tree health, particularly for young trees that are still establishing their root systems.

4. Light Pruning for Safety and Health

While extensive pruning is best saved for winter or early spring, light pruning during summer can be beneficial. The goal is to remove any dead or damaged branches that may pose a safety risk or attract pests.

• Removing Dead or Damaged Branches: Remove dead, diseased, or damaged branches as soon as you notice them. This helps prevent pests from being attracted to weakened areas of the tree.
• Avoid Heavy Pruning: Heavy pruning in summer can stress the tree and lead to excessive sap loss, which can weaken the tree. Focus only on light, selective pruning to shape the tree or remove hazardous branches.
• Pruning Tools: Use sharp, sanitized pruning tools to avoid spreading disease. Avoid pruning during high humidity or rainy periods, as this can increase the risk of fungal infection.

By limiting summer pruning to essential cuts, you help the tree conserve energy while maintaining a healthy structure.
