Many gardeners put tomato growing on the top of their must-do list in gardening. This happens mostly because of the incomparable flavors of this crop, which is easy to grow. Even if you don't have a garden plot, you can still grow them. You can enjoy some cherry tomatoes grown in a hanging basket or grow a few full-sized tomatoes in self-watering five-gallon buckets. Is it too early to think about your tomato plants? Not if you are a competitive gardener who needs the sweetest tomato on the block.
