• ✓ Harden off transplants by gradually increasing their exposure to sunlight over a period of a week or more.
• ✓ Prune lightly and avoid opening the canopy immediately before or during heatwaves.
• ✓ Maintain consistent soil moisture, apply mulch to reduce heat stress, and utilize drip or soaker hoses during hot spells.
• ✓ Utilize shade cloth during peak heat periods, particularly for tomatoes, peppers, cucurbits, and young trees.
• ✓ Select varieties with dense foliage and use stakes or cages to ensure leaves protect the fruit.
• ✓ Wrap young tree trunks or apply diluted white interior latex paint to the sun-facing side before winter, removing wraps in the spring.
• ✓ Position containers where they receive morning sun and afternoon shade, and avoid placing them near reflective surfaces that intensify heat.
• ✓ Avoid excessive nitrogen fertilization, which promotes sparse, tender growth that is more susceptible to sun injury.
