Part 4: Tips for Your Greenhouse
If you’re growing carrots, beets, turnips and other root crops, they thrive well in deep boxes which can be put under benches. Those that require tub-type containers are tomatoes, peas, cucumbers and pole beans, while lettuce, or other low leafy vegetables may be planted in the tub with the taller vegetables. You can plant corn directly on the floor of the greenhouse, in a special bed prepared for it. To save space, you can plant pumpkin between the rows of
corn. Use room temperature water to water your indoor plants.
Let tap water stand for a day to get rid of the chlorine substance. This way you avoid your plants getting brown tips. Distribute crushed egg shells in your garden to
stimulate growth. Sprinkling coffee grounds will add acid to the greenhouse ground. Before bringing vegetables and fruits from the greenhouse to your house, rinse them well outside; this way dirt and bugs stay outside and will not make your kitchen dirty.
To make more room in your greenhouse, use lower benches for starting seeds and transplants; upper benches for growing flowers and specimen plants. Some vegetables, like tomatoes, should be planted in a warm section of the greenhouse.
Regarding planting of seeds, be sure to water lightly for the first few times. Over watering may cause the seeds to come to the surface too soon, preventing them from rooting properly. Preparation and production must be done in separate areas. Don’t do general preparation on the growing floor. This makes for a tidier greenhouse. Here is a list of the largest vegetables that will need the most spacing in your greenhouse:
> bush type beans: minimum of five feet
>cabbage: a foot between rows,
>peppers: about a foot between rows,
>cantaloupes: two to three feet between rows,
> squash: two to three feet between rows,
>tomatoes and watermelons: minimum of two
feet between rows.
All other vegetables (beets, carrots, garlic, lettuce, onions, peas, radishes, spinach, and turnips): five to ten inches to grow fully in the bed in your greenhouse. For carrots, beets, and onions that grow deep down in the dirt, keep your soil at least two foot deep as the roots on some of these plants and the vegetable that grows from these plants can get to be very large under the soil.
Mixing vegetables in rows is a good idea. Plants that are different put side by side will not compete for the nutrients, soil and water. For example, take onions and lettuce. One grows down in the dirt while the other grows up from the soil – they grow well side by side. However if you were to put onions and carrots together, they will be competing for the soil space.
