Hi all, I just finished installing a drip irrigation system in my garden and bought this fancy digital timer. How many gallons of water should a tomato plant get per day or per week? My garden (which is at a friends house) is in sunny southern California near Los Angeles Airport. The area is often sunny with morning and evening fog at times. The soil is a sandy loam that drains fairly well and I am using black plastic mulch. I know Chuck and others espouse deep watering every so often...just how much would that be?
