I am terrible about watering the garden. My instinct is to wait till the plants look thirsty, maybe wilt a little. It's a habit from farming in the desert, which I am trying to fight against since water is so plentiful and cheap here. The plants really seem to respond to heavy watering with lush growth, but I also want to balance that with flavor. Tomatoes taste so sweet and unbelievably intense when they are grown on the dry side. Maybe I will increase watering to 3 or 4 times a week, and then taper off when the first flush of tomatoes start to change color.
Everything is growing fairly well so far, which makes me happy.
