What Can You Not Grow In A Greenhouse?

What Can You Not Grow In A Greenhouse

There are many things you can grow in a greenhouse. For instance, you can grow a citrus tree. You can also grow a pepper plant. However, the temperature should not go below 55 degrees overnight. It is also important to plant pepper plants at least 15 inches apart. Other plants you can grow in a greenhouse include eggplant and Kalanchoe.

Citrus trees produce crops

Citrus trees need a moist but not soggy soil and should be watered regularly. Avoid watering them too much or too little. It is also important to keep them from drying out completely. Infrequent but deep watering is better than frequent shallow watering. The frequency and amount of watering also depend on the temperature and humidity in the area. Too much watering can lead to yellowed leaves. It is also important to prune the citrus trees during winter.

Citrus trees are heavy feeders and should be fed monthly with a balanced soluble fertilizer. During fruit-bearing months, citrus trees are particularly fussy and should be given half strength fertilizer to avoid nitrogen shock. It is also important to use high-quality potting mix for citrus trees. A good mix contains sphagnum peat moss, sand, and finished compost. Finished compost is an important ingredient as it supplies the plants with trace elements.

Although citrus trees are not suitable for greenhouse production, they can be grown in containers. Given enough time and care, they will grow and produce fruit. The amount of fruit produced is proportional to the size of the trees. The container in which they are grown will also affect the amount of fruit they produce. The average citrus tree will produce a fair amount of fruit in a small container. Citrus trees are easy to grow and produce fruit, but they require some care. Most citrus problems will be minor and can be solved by minor cultural practices. However, some problems will require pesticides.

Pepper plants

Pepper plants thrive in the sun, but they need time to adjust to the outside conditions. During the early stages of their growth, pepper seeds can be extremely sensitive to drought. In addition, too much moisture in the soil can cause germination problems, as it limits the amount of oxygen in the soil and promotes mold growth. If you are growing pepper plants in a greenhouse, you should follow best practices for greenhouse pepper gardening, such as using organic methods and providing ample light and water.

Peppers grown in greenhouses can produce two or four heads per plant. Two-headed plants will produce larger peppers and require less energy to produce. Four-headed pepper plants are more popular in Holland and North America, where the market is dominated by large bell peppers. However, in greenhouses with hot summer temperatures, two-headed plants may be more appropriate.

Peppers require a temperature over 80 degrees for them to grow at their full potential. If they are grown in a greenhouse without heating, their growth rate will be much slower. A lack of nutrients can also prevent pepper plants from producing their full potential. Using slow-release fertilizers with balanced N-P-K levels is a good idea. Soil testing is also important to identify pH problems and nutrient deficiencies.


Kalanchoe is not an ideal choice for greenhouses because of its low tolerance for cold temperatures. This succulent is perfectly content to grow outdoors in warm summers, but it must be protected from hot afternoon sun. Its leaves will burn if exposed to full sunlight. However, this plant can be grown indoors during cooler seasons as long as you follow a few simple guidelines.

The best place to grow kalanchoe indoors is a location with indirect light. It should not get direct sunlight because this will cause the leaves to turn purple and eventually scorch. It also needs a six-week cycle of shorter daytimes and longer nights. Deadheading and proper watering are also important for a healthy plant.

Kalanchoe species that flower in response to day length are called photoperiodic. They flower when the daytime length is equal to or less than 12 hours. During the winter months, they flower when the daytime is less than 12 hours. This makes them excellent for greenhouse cultivation.
