The hottest days of summer are almost here, and the tomatoes are setting fruits; it is important now to water, fertilize, and stake the plants so that they will bear over a long period of time.
Water is essential, but how it is made available to the plants is the main point. If plants are watered stingily their fruits will get “bottom rot”. This is caused by the plant not being able to “uptake” enough water properly. Tomatoes are tropical plants and require lots of water.
