How to Grow Greenhouse Tomatoes


A greenhouse is a type of indoor garden made up of glass panels secured into a steel frame. Greenhouses optimize the sun's light to generate enough heat to grow heat-loving plants year round. The most popular plant for greenhouse growing is the tomato. With its lush foliage and delicious fruit, it is no wonder that backyard gardeners do everything in their power to enjoy this plant year round. Growing them inside a greenhouse is relatively simple.

Step 1

Place two to three medium stones at the bottom of the planting pots around the bottom irrigation hole.

Step 2

Fill the pots with a mixture of half potting soil and half peat moss.

Step 3

Place the tomato plants into their pots, one plant per pot.

Step 4

Secure the plants to the ceiling of the greenhouse once they are 10 inches high, to prevent them from tipping.

Step 5

Prune the plants so that they are growing vertically from one main stem. Remove other lateral branches once they approach 1 inch long.

Step 6

Fertilize the greenhouse tomatoes two weeks before the first tomato will ripen, two weeks after it ripens, and one month later using a 10-5-10 fertilizer.

Step 7

Rent or purchase bumblebees to pollinate your plants.

Step 8

Prevent insects from feeding on the new crop by purchasing some biological control insects. The specific insects vary from region to region. For information on your local varieties, contact your county extension office.
