If I were to dig down a foot or so and bury a pie tin below my tomatoe plants, Would it trap water? And do any good?
How are you watering? Were I to try this I think I would bury a clay pot but I like the idea for an experiment. I would definitely suggest several with and several without the pie tin or whatever. If you only do one how do you know it whether it was affective or not?
Good point on the clay pot. Maybe I will look for a plastic ? at Big Lots or .99. I drip irrigate. I have good soil. The thought crossed my mind. I dont know if the water would go a foot down, or dissipate out.
