Tomato varieties differ not only in the taste and size of the fruit, but also in the method of planting the bush. Tomatoes are grown in open or closed ground, like many vegetables. Depending on where the bushes will be planted, the required variety is selected.

However, for various reasons, the bush may be planted in unsuitable conditions. Then, in order for it to bear fruit, you need to properly care for it.

In the article we will tell you what are the differences between street and greenhouse varieties, as well as whether it is possible to plant street tomatoes in greenhouses.

Differences between street and greenhouse varieties of tomatoes

Usually, more capricious varieties of vegetables are grown in the greenhouse. Including tomatoes. This is due to the fact that it is easier to create suitable conditions in the greenhouse. Greenhouse tomatoes are usually more capricious, react more strongly to temperature changes and are more susceptible to diseases.

Outdoor tomatoes are better suited to harsh conditions. They are not afraid of the coolness of the night and the bright daytime sun. They are also less likely to fall ill with late blight.

Another factor in choosing a cultivar for a greenhouse can be the type of bush. Tomato bushes are determinate and indeterminate. They differ in the nature of the growth of the bushes.

Indeterminate tomatoes are great for a greenhouse. For open ground, determinant varieties are usually chosen. They are less whimsical to care for and do not require support in the form of a garter or bush support.

Can outdoor vegetables be grown indoors?

Tomato varieties intended for outdoor use can also be grown in a greenhouse. In this case, they are also not whimsical. At the same time, they can give more harvest than in the open field. Sometimes growing these tomatoes in a greenhouse is more economical. This is especially true for the cold northern regions.

Possible difficulties

A greenhouse is a good way to maximize your harvest and extend the harvest time. but when growing tomatoes in a greenhouse, certain difficulties may arise:

  1. Lack of light.
  2. Increased temperature and lack of air circulation.
  3. Improper watering.

However, with proper care, these problems can be effectively dealt with.

Necessary conditions for such cultivation

To avoid problems with growing tomatoes indoors and get a good harvest, you need to follow the following rules:

  • For a tomato, abundant lighting is important. If determinant and indeterminate varieties are grown in the same greenhouse, then they need to be arranged so that taller plants do not block the sunlight with low bushes.
  • Tomatoes do not like heat and stuffiness. Therefore, after the required lighting level is set, you need to monitor the temperature. You can install a thermometer next to the tomatoes so that it is convenient to monitor the indicator. The optimum temperature for tomatoes is 24 0C, at temperatures above 39 0Tomatoes wither and cease to form ovaries.

    To achieve optimal performance, it is necessary to provide for the possibility of ventilation. It is good if there are vents in the greenhouse that can be opened and closed if necessary. The main thing is that they do not create a strong draft.

  • Tomatoes need proper watering. In the greenhouse, the moisture content of the soil must be monitored carefully. Young seedlings need to be watered every day and little by little, and already mature bushes can be watered once a week, but abundantly.
  • There is an opinion that some varieties of tomatoes in greenhouses will not be able to pollinate. However, this is not true. All tomatoes are self-pollinated plants. This means that the flower has both male and female organs, and they do not need additional pollination by insects.

    For better formation of ovaries, it is worth considering the possibility of additional pollination. This will help the vents provided for ventilation. You can also carry out pollination yourself by hand.

The greenhouse must have a ventilation window. It is better to place them in the middle or upper part of the building. Plant stems should be lower than the vents. Timely airing will make it possible to regulate not only temperature, but also humidity. This will help to avoid stem rot and the occurrence of fungal diseases.

Features of planting and caring for tomatoes in a greenhouse facility

It is necessary to plant tomatoes, even indoors, only after the frost has passed. It is advisable to plant seedlings on a warm, but not too sunny day. It is not necessary to bury the seedlings in the ground, only if they have not greatly outgrown.

In addition to the above rules, for effective care, tomatoes need feeding. You need to feed tomatoes after the formation of the first ovary on the bushes. You can finish feeding in the second half of July. Potash fertilizers are most suitable.

Reference! Tomatoes cannot be fertilized abundantly with organic matter. This will increase the green mass, but the harvest may suffer.

With good care, tomatoes intended for open ground feel great in shelter. Observing simple rules, you can achieve a good harvest.
