One way of outsmarting tomato diseases may be to plant a wide variety of disease-resistant tomato plants, not just one variety. Even if you lose one or two tomato plant to the disease, the other varieties could resist it. Also, space the tomato plants well apart from each other. My tomato plants were scattered around the garden, well apart from each other, and this probably saved some of my plants.
The best place to grow tomatoes will have full sun for six hours a day. Hotter southern locations might need a little afternoon shade to give the tomatoes a bit of relief so they can survive and thrive. A well-drained site with rich, loamy soil is ideal. If you don’t have a location with full sun for six hours a day, you might have to trim back some tree branches. If your soil isn’t ideal, start adding organic material like compost to it.
If you have a limited amount of space, or if you have terrible soil, then you can grow your tomatoes in a container. A number of determinate tomato varieties are specially bred for this purpose, bearing a nice bunch of tomatoes in a small pot.
