How to Grow Tomatoes & Zucchini From Seed


Some of the easiest vegetables to grow even for novice gardeners are tomatoes and zucchini. Whether you have experience with these productive plants or not, to grow tomatoes and zucchini from seed can be a rewarding pastime with tasty benefits. As you plan your garden, be sure to leave room for one to two zucchini plants and four to six tomato plants per household member to supply your home with fresh vegetables over the growing season.

Step 1

Select a full sun area for your garden bed and loosen the soil by digging 8 to 10 inches deep. Remove rocks, roots and twigs as you break up clumps of dirt and mix the lower soil with the upper soil.

Step 2

Add 4 inches of compost or garden soil over the bed and use the shovel to turn the soil to mix the compost in well. Wait until after the last frost in your area before planting your seeds.

Step 3

Plant tomato seeds 1/2 inch deep spaced 2 feet apart with rows set 3 to 4 feet apart. Plant zucchini seeds 2 to 3 inches deep, 3 to 4 feet apart. Use your hands to create a circular basin around each planted seed area about 8 to 10 inches in diameter and 1 inch deep.

Step 4

Water your seeds by filling the basin with water and allowing it to drain into the soil. Fill the basin once more and let the water soak in again to fully saturate the soil. Keep the soil around your seeds damp for three to four weeks as they germinate and start to grow.

Step 5

Set up tomato cages around each of your tomato seedlings to help support them and encourage the plant to grow vertically. As the tomato plants grow you may need to use plant ties to train them to the cages.

Step 6

Feed your seedlings with a low-nitrogen fertilizer that dissolves in water or sprinkle granules on the ground monthly and work them into the upper inch of soil. Stop applying fertilizer to your tomatoes after fruits begin to form; you can continue to feed the zucchini monthly for the life of the plant.

Step 7

Water your growing plants well once or twice a week by filling the basins around the plants multiple times until absorption slows. When you water, look out for weeds growing around your plants and pull them out as you see them.

Tips and Warnings

  • Avoid wetting the leaves of your plants when you water to keep diseases such as powdery mildew away. Treat your plants with pesticides that are safe for edible plants as needed when you see pests. Regular checks over your plant can help you spot the first few bugs before they multiply.
