Tomatoes can be very temperamental, and if not cared for correctly, you can end up with few fruit or mostly green tomatoes.  Water is key to a healthy plant.  Expect to water about 1” per week during peak tomato growth. Using a mulch will help reduce water loss.  Overwatering can cause increased leaf growth at the expense of tomato fruit.  Too much water also encourages disease problems.
