How to Grow a Tomato Plant Indoors

Overview

Growing indoor tomatoes is all about choosing the right varieties. According to the University of Illinois, small-fruited and salad tomatoes, as well as dwarf and container varieties, are best for growing indoors. Tiny Tim, Cherry Gold and Mountain Belle are some of the best indoor varieties. Growing your own tomatoes indoors can provide consistent tomatoes throughout the year without relying on air-freighted fruit from around the world.

Step 1

Germinate the tomato seeds in a small pot filled with potting soil suggest Colorado State University. Bury the seeds 1/4 of an inch deep, and water until the potting mix is moist. Seeds will germinate during a period of five to 10 days.

Step 2

Hold a stake vertically in your final tomato container, with the end touching the bottom of the container, and partially fill the container with soil. This holds the stake in place.

Step 3

Transplant the seedling from the starter tray into a 6-inch pot once the seedlings are 3 inches in height says Colorado State University. Use a commercial potting mix and bury the seedlings at the same depth they were planted in, close to the stake.

Step 4

Water the plant when the soil is slightly dry to the touch, but not completely dried out.

Step 5

Fertilize the plant once a week using a water soluble fertilizer with a 20-20-20 or 15-30-15 mix says Ohio State University. Moisten the potting soil before adding fertilizer, as dry fertilizing will cause run off of the fertilizer material.

Step 6

Harvest mature fruits as they appear, to increase production and promote good fruit growth.
