One of the most important aspects of tomato growing is selecting a location for your plants that will allow them to flourish.
Tomatoes need plenty of sunshine and a good rule of thumb for ensuring they get enough, is to find a spot in your garden that sees a minimum of 6 hours of sunshine a day. Some will argue that tomatoes need as much as 10 hours of sunshine a day and if you have a spot that can deliver that amount of sunshine then it certainly wouldn’t do any harm; assuming of course you don’t allow the plants to dry out.
