How to Grow a Healthy Tomato Plant


Homegrown tomatoes fresh from the vine are full of flavor and nutrition. Growing your own tomatoes can be a fun family project with the help of a few simple procedures. Tomatoes come in two main types: determinate and indeterminate. Determinate type tomatoes are bushy and produce all of their fruit at the same time. Indeterminate tomatoes are vine-like, and produce over a longer period of time. Choose the type and variety that grows well in your climate and is resistant to local pests and diseases.

Step 1

Choose a sunny location with good drainage. Amend the soil with organic materials such as compost or peat moss. Mix into the top 6 to 8 inches of soil.

Step 2

Get a soil test and follow the recommendations for pH and fertilizer. If no test is available, use 3/4 cup of lime for each plant. Mix into the soil before planting.

Step 3

Start seeds indoors four to six weeks before the last frost date or purchase transplants. Look for plants that are compact with healthy foliage.

Step 4

Plant tomatoes 18 to 24 inches apart in 3- to 4-foot wide rows. Place the transplants in the ground an inch deeper than they were originally planted, burying part of the stem. Firm the soil around the plant.

Step 5

Water after planting and apply a weak fertilizer solution. Mix three to four tablespoons of 8-8-8 fertilizer into a gallon of water. Use one cup of this starter solution per plant.

Step 6

Stake or cage tomato plants for support. Insert a 6-foot stake into the ground next to the plant and tie the tomato plant loosely to the stake with cotton twine. Place tomato cages around the plant and drive 3 stakes in around the cage for extra support.

Step 7

Add a layer of 3 to 4 inches of organic mulch to the bed to help conserve water and discourage weeds.

Step 8

Water plants in the morning whenever the top of the soil is dry. Remove weeds as soon as they appear by hand pulling or a light hoeing.

Step 9

Apply one to three tablespoons of 8-8-8 fertilizer as a side-dressing when the first tomatoes begin to set. Repeat this application every four to six weeks. Keep the fertilizer at least 4 inches away from the tomato trunks.

Step 10

Use a shade cloth in tropical climates. Tomatoes will wilt and die in extreme summer heat unless protected.
