Features of indeterminate varieties

Indeterminate varieties - tomato unlimited growth. Their stem will grow as long as there is room for it, and as long as the weather conditions allow it. Determinant, on the contrary, are called plants of limited growth, which turn into a short bush and begin to bloom and bear fruit.

Both options are suitable for growing in greenhouses, but they have a number of important features:

1. Determinant varieties are planted along the edges of the greenhouse or greenhouse so that the roof slope does not interfere with their growth. In contrast, indeterminate varieties are best placed in the middle of the greenhouse, as the plant will still receive sufficient sunlight. At the same time, they are more resistant to fluctuations in weather conditions, and they are just perfect for greenhouses.
2. Indeterminate varieties require more careful care, they are distinguished by higher yields. More than 50 kg of fruit can be obtained from one bush, especially if you take care of regular watering and sufficient lighting for the entire plant. It is better to grow it in a greenhouse in combination with medium-sized bushes, then nothing will block the light.

Tall varieties must be tied up, otherwise the stem may break. You can place the plant on a trellis, then it will give flowers and fruits along the entire height of the stem. The height for the first row of the garter is at least 2-3 true leaves. When growing, the side stepchildren are removed: one main trunk is formed, which will allow you to get a large number of fruits.

Indeterminate varieties are more profitable to grow in regions with warm climates, as they require a lot of sun.

And vice versa: determinant varieties thrive in areas with cool climates, and it will be easy for them to find a place even in a low greenhouse. You can also choose an intermediate solution: there are semi-determinant varieties, which have a lower stem than indeterminate ones, but it will be stronger. This allows you to simplify plant care and in the same way get a rich harvest.

Because of this, the growth of the bush is less, and it is easier for him to find a place in an ordinary greenhouse. The fruits have another important advantage: during transportation and storage, they do not crack, which provides them with a longer shelf life.

These are just some of the varieties, the choice for gardeners is much wider. When buying seeds, you need to pay attention to the inscriptions on the back of the seed bag: it gives not only an indication of the type of variety, but also indicates the main growing recommendations.

Some tips for growing tomatoes in a greenhouse

Indeterminate varieties have a number of cultivation characteristics. Knowing their characteristics will allow you to avoid mistakes and ensure regular high yields in the future.

Consider a few tricks that have been tried out many times by experienced gardeners:

• Several underdeveloped fruits can be cut from the brushes so that the rest become larger and stronger. Gardeners can tell many stories that they managed to grow tomatoes weighing up to 1 kg. It is hard to believe in this, but the fact has been proven that when you remove one or two fruits from a branch, you can get larger tomatoes.
• It is recommended to combine varieties of different types in one greenhouse: indeterminate and determinant, early and late ripening, salad and pickling. This will allow you not only to get a rich harvest from each bush, but also to please yourself with different tastes.

• Another simple trick: flowering and fruiting can be accelerated by increasing the concentration of carbon dioxide in the atmosphere. To do this, you can put a bucket of manure in the greenhouse: the acceleration of biochemical processes will be harmless to plants, and the result can exceed all expectations.

These guidelines work for both determinant and indeterminate varieties. If you combine tomatoes and grow the next generation from seed, you can get interesting hybrids that combine the features of both varieties.
