How to Plan for Success This Summer

Summer is a good time to focus on the key practices that support healthy tree development and long-term orchard success. In California’s Central Valley, extended periods of heat are the norm, with temperatures frequently reaching the high 90s and exceeding 100°F for four to six months out of the year, typically from late spring through early fall.

With these prolonged hot conditions, small adjustments in irrigation, protection, and planning can make a significant difference in overall tree performance. As temperatures rise and conditions shift, here are a few areas to keep top of mind as you prepare for the months ahead:

As we move into the warmer months, proper orchard and nursery management becomes critical.

Irrigation should be top of mind:

• Regularly check emitters to ensure accurate output and uniform coverage
• Inspect systems for clogging or pressure inconsistencies
• Adjust watering schedules to match increasing temperatures and evapotranspiration rates

Heat protection planning is equally important:

• Apply foliar protection materials ahead of anticipated heat events
• Ensure trees are not entering extreme heat already under stress

For newly planted trees, tree wraps remain essential. These wraps help protect trunks from direct sun exposure, reducing the risk of sunburn and heat damage during peak afternoon temperatures. Protecting the trunk early allows for stronger establishment and long-term health.
