6 Best Cultures To Grow In Small Greenhouses

Wondering what you can grow in a greenhouse?

Once you have your greenhouse set up, you might be stuck at trying to figure out how to start growing plants in it The first step is figuring out whether you will be growing vegetables in a greenhouse or fruits.

When you are a beginner looking for what to grow in your greenhouse, growing vegetables is an excellent choice. It's immensely gratifying to be able to grow and eat your vegetables.

Here are some of the best vegetable to grow in greenhouses, some of which are suitable for beginner gardeners and some who can even be grown in winter:

Broccoli

Those who are beginners to using a greenhouse should consider growing broccoli. This vitamin-rich vegetable can grow in the simplest of greenhouses. They don't require extra heating and can be quickly grown in unheated backyard greenhouses, and thus great for beginner gardeners.

Broccoli.

Like most other cold season vegetables (like beets, cabbage, cauliflower, carrots, radishes and leafy greens), broccoli needs a cool but not freezing temperature to grow. In regards to temperature, broccoli will thrive in a 50-70 degree Fahrenheit environment during the day and 45-55 degree Fahrenheit setting at night.

They don't require a lot of light so you can take advantage of the darker corners of your greenhouse. Just be sure to keep the greenhouse cool and well ventilated.

Tomato

Tomatoes are one of the most popular vegetables/fruits to be cultivated in greenhouses, both commercially and by home gardeners.

Tomatoes are a warmer weather vegetable (like cucumbers and peppers), so they require the greenhouse to provide them with consistently warm surroundings.

Tomato.

Tomatoes grow best during daytime temperatures that range between 70-80 degrees Fahrenheit and nighttime temperatures that range between 60-65 degrees Fahrenheit.

Tomatoes are susceptible to rot, so make sure that the greenhouse is well ventilated and the humidity is regulated. This applies to the soil as well; it must be well drained.

Tomatoes are trickier to grow, as they are demanding regarding temperature, light, moisture and even soil pH. For a big and healthy crop, it is necessary to fertilize and prune the tomatoes plant regularly. Also, remember to allow for enough growing space, as a tomato plant can grow up to 6 inches a week during its peak growing season.

Summer Squash

Summer squash and similar vegetables, like zucchini, have very high yields in greenhouses. A single plant can keep a person fed for a long time frame. They are also very easy to grow.

So, if you are a beginner gardener, a squash plant will keep your spirits up, even if all other plants fail you.

Once the temperature inside the greenhouse reaches 65 degrees Fahrenheit, you can start germinating squash seeds. Just make sure they don’t overheat in the summer or develop rot, by keeping the greenhouse well ventilated.

Also, don’t let the squash to its own devices or it will grow wild. In smaller areas, like greenhouses, it’s best to steer the growing shoots upwards.

Winter Spinach

Spinach can be a little tricky to get started, but with a little care it can grow during winter and can be harvested or cut from several times, increasing its yield.

Spinach grows best in a fertile, nitrogen-rich soil. Since spinach can be little finicky to get sprouted, make sure you plant more seeds than you intend to grow, to make sure. Winter spinach is especially susceptible to mildew, so allow for enough space between plants for air to circulate.

Spinach.

Winter spinach can easily overheat in a greenhouse, making proper ventilation critical. To encourage the late winter harvest that's usually during February and March; it is essential to keep the soil fertile by adding fertilizer in as soon as new growth appears.

Lettuce

Lettuce is another common greenhouse crop and is one of the easiest vegetables to grow year-round. Choose a loose-leaved variety so you can cut the lettuce and then leave it to grow again. No messing about with seeds.

Make sure the greenhouse can maintain a constant temperature between 55 and 75 degrees and has plenty of light. For perennial crops, seed some new plants every couple of weeks, so you always have plants at the growth level you need for cutting.

Lettuce.

Once the lettuce leaves reach the desired height, cut them off leaving about 1 inch above the crown of the plant. You should be able to get about three cutting from each plant.

Strawberries

Strawberries are a good option growing in your greenhouse, especially if you grow them organically since they are especially susceptible to retaining harmful chemicals used in commercially grown strawberries.

Strawberries prefer slightly acidic soils (6.5 pH), which you can raise organically by adding pine needles. Make sure the soil is rich in nutrients and well-drained.

Pick a certified starting plant. It will help you reduce the risk of your strawberry plant contracting the common verticillium wilt. Also, don’t plant it close to tomatoes or eggplants, since they are susceptible to the same disease.

Strawberries.

Strawberries are shallow -rooted. That means that the soil needs to be well watered (not a lot, just be kept moist). Because it is a shallow rooted plant, it has a harder time competing with weed, so make sure you weed regularly.

Exotics

Remember, given the right conditions you can grow all sorts of exotic plants in your greenhouse. Think for example of sweet or chili peppers, sweet potatoes, melons, or lemons.

If you are looking for more exotic things to grow in your greenhouse, here a couple that could even make you some money: ginseng, gourmet mushrooms, bamboo, exotic herbs, medicinal marijuana. With the right conditions, you can even grow tropical plants like orchids and carnivorous plants.

Also, why not dedicate a part of your greenhouse to growing ornamental flowers like geraniums, poinsettias, petunias or Chrysanthemums.

The sky, or rather the soil is the limit when it comes to what you can grow in your greenhouse.
