Land preparation
The GS-12 f1 hybrid is grown in almost any soil; the variety does not welcome only heavy, wet soil, but the fruits ripen even in it if the bushes are planted on a ridge. The soil for tomatoes is dug up in the fall. You need to choose an area where potatoes or eggplants did not grow, since these crops are affected by the same diseases.
With the seedless method of cultivation, which is possible only in the southern regions, the soil is leveled so that there is the same depth when sowing. To conserve moisture in the spring, soil tillage is minimized.
Before planting tomatoes, the soil is fertilized with minerals - nitrogen, phosphorus and potassium. During the growing season, fertilizing is also necessary.
Seeds germinate when the temperature rises to 15 degrees.In the south of Russia and Ukraine, seedlings are moved into open ground starting in the third ten days of April, in the middle zone - from May 10 to May 25. 7 hybrid bushes are planted on 1 square meter. When growing in seedlings:
- The harvest is harvested early.
- Tomatoes do not die from frost.
- Fewer fertilizers and fungicides are used.
- The density of the leaves is regulated.
The disadvantage of this method is that the root system develops worse than when sowing directly into open ground. Bushes take longer to adapt to new conditions.
Features of care
The maximum harvest is harvested if the night temperature is about 18 degrees. The tomato needs to be freed from stepsons and excess ovaries. Crop care includes:
- fertilizing the soil;
- ties up bushes;
- mulching;
- hydration.
You need to water the tomatoes at the root, making sure that water does not get on the leaves and inflorescences. Drip irrigation is best. Mineral and organic fertilizers must be added to the soil regularly.
If you follow the rules of agricultural technology and timely hydration, the tomatoes will be rewarded with dense and tasty tomatoes.
