Successful August gardening is a balancing act between heat and plant needs. That’s a real challenge during drought. You can still keep your tomatoes happy while saving water.
Keep an eye on your vines during hot weather. Tomatoes can wilt easily when the temperature hits triple digits but will usually bounce back overnight. The goal is to keep soil moisture levels consistent and avoid issues such as blossom end rot. Give your plants a deep watering two times a week, more if they grow in containers. A mature bearing tomato plant needs about 5 gallons a week.
Elsewhere in the garden this week:
Give vegetable plants a boost with phosphate-rich fertilizer to help fruiting. Always water before feeding.
