|I have several plants and wondered how much watering is required during the hot months. Growth of fruit is sluggish.
|Tomato pollen isn't viable much over 90 degrees, so new fruit won't set, and growth of existing fruits seems to slow down. Tomatoe plants are moisture sensitive and need a regular supply of water to thrive and produce fruit. How often to water depends on your particular soil's characteristics and weather conditions. You want to keep it uniformly moist, but not soaking wet, to a depth of 12 inches. Poke a long, sharp metal pole or long screwdriver into the soil. It will move easily through moist soil, stopping abruptly where soil is dry. Layer compost mulch or straw on top of the soil to maintain moisture and reduce soil temperatures. Good luck!|
