Two Types
If you don’t have a lot of space, go for determinate tomatoes, which grow to a fixed point and then stop. Indeterminate tomatoes keep growing and producing fruit through the summer and into the fall. Use stakes or trellises to separate tomato plants.
Sun and Soil
Tomatoes need a lot of sun and light soil for aeration and water penetration. If you have clay soil, which can easily get waterlogged, add compost to improve texture.
Raise Them
Tomatoes do much better on raised beds than on flat soil. Make sure to plant them deep.
Shared Space
Grow marigold or basil next to your tomatoes—they repel many insects.
Keep Away
Don’t plant your tomatoes next to walnut trees or potato plants: They are both susceptible to fungal diseases that can spread.
