For years and years I have tried to grow tomatoes. And it is so hot and dry here that they are never very happy and don't produce many tomatoes. This year, I came up with what I am hoping will be a solution to the extreme heat and lack of humidity. What I did was put my Tomato Plants in a wading pool with shade cloth over the top of them. They are able to get early morning sun and are sheltered from the afternoon sun. The shadecloth keeps in some of the humidity and with the pots sitting in water, the soil stays evenly moist. I still have to water them twice a day on the hottest of day. But, now they don't dry out between waterings which causes them to be too stressed. They have lots of flowers and I hope to this year actually get some decent tomatoes.
