To collect an enviable crop of tomatoes in a room garden, you need to go a long way. Let's get acquainted in more detail with the agricultural technology of growing tomato seedlings for the windowsill
Caring for seedlings of indoor tomatoes
To grow seedlings of indoor tomatoes, you can use flower pots with a diameter of about 10 cm or put together small boxes from scrap materials. In such containers it is possible to place 20-30 plants for the time being. After all, more is not needed for indoor gardening. From here, the seedlings will later move to wider beds.
After sowing, the seed containers are left in a warm place. Here the air temperature should be at least + 22 ° С, and it is better if everything is + 25 ° С. But when the shoots appear, then the conditions of detention must be radically changed. At this stage of development, plants require growing temperatures within the range of + 12 … + 15 ° С. In addition, the pots should be placed in a well-lit area. This regime is maintained during the first week. Then the temperature must be raised again to at least + 22 ° C.
Operation of picking tomato seedlings
For picking seedlings, individual pots with a diameter of 8 to 12 cm are selected. They are not stuffed with soil mixture to the very edges. You need to leave 2-3 cm in case of exposing the roots or compaction of the substrate, in order to be able to add more earth.
They start picking seedlings when a pair of true leaves are formed in the plants. Remove the tomato from the ground and shorten its root by a third. You can simply pinch it off with your fingers. Transplanted tomatoes are watered with warm water. Then the pots are placed in a shaded place for the first time. Here the temperature should be approximately + 20 ° C. In such conditions, seedlings take root better. After the rooting process has successfully taken place, the pots can be sent back to the sun. In this case, during the day it is recommended to keep tomatoes at + 20 ° С, and at night, reduce the degree to + 10 … + 12 ° С.
Care for seedlings of indoor tomatoes
One and a half to two weeks after the pick, plants should be fed. A mullein diluted with water in a ratio of 1: 8 or a less concentrated solution of bird droppings (1:12) is perfect for this. Fertilizer consumption - 1 glass of such a mixture for 4 plants.
If in urban conditions there is nowhere to get organic fertilizers, specialized stores will help out. Here you can stock up on mineral supplements. To prepare a nutrient solution for seedlings, for 1 liter of water you will need:
• superphosphate - 3 g;
• potassium sulfate - 2 g;
• urea - 1 g.
Top dressing is repeated after another 10 days. But this time the amount of fertilizer for one plant is doubled. The third feeding is done 5 days before the planned time for transplanting seedlings to permanent indoor beds. Now you need a glass of nutrient mixture for one tomato.
As for watering, it is very important not to overmoisten the soil. Depending on the structure of the soil - its ability to absorb and evaporate moisture - watering is done regularly every 3-7 days. The water should be warm, about + 25 ° C. If after that the roots become bare, do not forget to tame them with an additional layer of earth.
Transplanting indoor tomato seedlings to a permanent place
Plants are transplanted to permanent beds when the seedlings have reached a height of approximately 10-12 cm. This requires pots or jars of about 4 liters. Boxes, plastic bags, or bags can be used. The main rule is to make a drainage layer in this container. It is also recommended to install a garter peg. Ladders, which are used to support indoor plants, are also suitable for these purposes.
As soon as the tomatoes take root in a new place, they will need to be fed. As a rule, this happens on the 5-7th day. This time, ingredients are taken in the following amount for 1 liter of water:
• superphosphate - 5 g;
• urea and potassium sulfate - 1 g each.
In addition, further care will consist in infrequent regular watering - once a week, as well as the formation of a tomato bush.
