Water them regularily. Avoid planting in a spot where tomatos, peppers or eggplants have grown in the past year or two. To prevent green potatos mound your soil up around your potato plant once a few leaves sprout. You can lift the whole plant. Potatos are from the same family as tomatos.
Tomatos are easy to grow but grow best in full sun in well drained beds.
Do not plant tomatos in the same area each year or they may be affected by nemotodes. Tomatos are officially a fruit but are commonly considered a vegetable. Plant marigolds, borage, basil and parsley near your tomatos for improved flavor, pest control and increased blooms. To prolong the life of your tomatos in the fall, take a 3 inch piece of copper wire and poke it right through the main stem of your tomato plants to protect from blight. WHY this last tip works.
