After a cold, wet spring, we are now having a dry, hot summer! When temperatures are above 90°F, plant growth is slowed. Leaves may fold or get scorched. Blossoms and fruit may drop. Yellow leaves can signify too little AND too much water. Watch your plants and check the soil to know when and how much to water.
- Plants wilt under heat stress and will recover when temps are between 59°-86°F.
- Always check the soil before watering. Stick your finger under mulch 1″-2″ into the soil. If dry, water.
- Water the base of the plant slowly and thoroughly with cool water, preferably in the morning. Watering the leaves can encourage pests and disease.
- Annuals in containers and hanging baskets require watering more often than plants in the ground.
- Plants under trees may require more watering as they compete with the tree roots for moisture.
- Add 1″-2″ mulch around plants in the ground to help regulate soil temperature and hold in moisture on hot days.
- Leaves with brown edges or dry spots are a survival strategy that plants use to stay alive. The edges can become brown or dry but still be viable. You do not need to cut them off. (These dry edges can also resemble some diseases symptoms, so decide if it’s a water issue or another problem before you water or treat them.)
- Create cooling evaporation for plants by hosing down nearby patios and walkways.
- Move stressed plants in containers and hanging baskets temporarily to shade for recovery.
