Overview

Having a short growing season used to limit the ability to grow vegetables. This is no longer true since greenhouse kits have become cheap enough for anyone to build a greenhouse. Greenhouse gardens are most effective when combined with container gardening. With proper planning, anyone who wants to can grow a greenhouse vegetable garden.

Step 1

Purchase and build the greenhouse kit. Use the greenhouse of your choice and size. Place the greenhouse where it will gain the most sun on your property. The best location will be facing north or south so the greenhouse roof makes the most use of the sun.

Step 2

Purchase containers and trays to hold your vegetable garden. Use clay containers to get the most longevity out of them. Use containers with a 12-inch radius. These will hold both individual larger plants, such as tomatoes and broccoli, as well as multiple units of smaller vegetables, such as herbs and carrots.

Step 3

Plan the layout of your greenhouse vegetable garden. Place smaller crops around the outer edge of the containers with larger or taller plants in the middle. Place like items or multiple varieties of a vegetable in one container to keep identification simple. Draw an overhead view of each container and list what will be placed in each container. Draw the containers on paper in the order where you will locate them in the greenhouse; this will also help keep larger plants and plant groups together.

Step 4

Place the shelving in the greenhouse. Use an economical layout to allow easy access to all of the crops from as many angles as possible. Use a tiered effect to make the most of your space. Remember that taller plants such as tomatoes, some lettuce, beans and broccoli should be placed as low as possible because they can grow up to three feet tall. Place cucumbers and vine vegetables in hanging containers to provide enough room for them to grown over the edge of the containers.

Step 5

Fill the containers with potting soil and fertilizer. Use the directions on the fertilizer bag to measure the proper amount to use. Fill the containers to within an inch of the rim so that when you water, the water doesn't overflow.

Step 6

Plant the seeds for the vegetables in their respective containers according to the seed packet directions for that plant. Place a wooden stick in place for each vegetable and use the seed pack as an identifier. Water the soil with the watering can. Wait for about two weeks to see results.

Step 7

When sprouts reach two inches, begin thinning out plants according to directions on the seed packets. This will allow the remaining plants to properly grow. Remember that when growing vegetables from starter plants, you do not need to thin out the plants; plants such as tomatoes, broccoli and peas are in this category.

Step 8

Continue daily maintenance until your vegetables reach maturity. Certain plants such as beans, peas, broccoli and peppers produce multiple crops over the course of a season if maintained properly. Weed, water and prune any damage for each plant to get the best crop.
