Watering Tomato Plants
We have two planted in the ground (tomato plants). Both have a lot of blossoms and the one plant has two tomatoes. They have never been fertilized and they get a deep root watering twice, maybe three times a week. We live in Phoenix, Arizona and it's beyond hot. The plants get full sun until about two in the afternoon. The problem is the leaves turn yellowish and then brown and shrivel up. Should they be fertilized, and are we watering too much or not enough? We are first time tomato growers and any help would be appreciated.
