Among the existing varieties and hybrids of tomatoes is difficult to give preference to one option. Each is distinguished by a certain taste and commodity qualities. But agricultural technology in general consists of general rules, which should be implemented in a timely manner. How to grow tomato seedlings, what is the optimum temperature it can withstand and what to do if it is frozen further in the article.
Timing for planting tomato seeds on seedlings
Do not rush to seed. It is important to adhere to the terms recommended by the selected variety. Some gardeners excel at planting seeds in January. In principle, seedlings can spend about 60 days on the windowsill, , but by the time of transplantation, their stems and foliage will be stunted due to lack of light and violation of the conditions of the containers with seedlings.
February, starting from the second half, may be the starting period for tomato seeding. However, there is a prerequisite - the whole process should take place in a heated greenhouse with good lighting. Window sills of city apartments are not adapted for this. If fluorescent lamps can help with the additional light, then it is unlikely to adjust the temperature and space conditions.
Experienced gardeners have set for themselves the optimal time for seeding - mid-March. The seedlings will receive a sufficient amount of light, which is important for the normal growing season of the plant. Early ripening varieties can be planted in early April. In cloudy weather it is necessary to illuminate the containers with seedlings, this lays a high yield.
How to plant seeds in an
box. Seedlings are grown at home in separate pots or cups, but most often a wooden box is selected as a container. Disinfect it before use. This can be done with a solution of blue vitriol( 100 g. In a bucket of water).Container parameters must comply with: a height of at least 8-10 cm, a length and width of 30x50 cm.
About a week before sowing the soil mixture is prepared:
- soddy earth( 1 piece);
- humus( 1 part);
- sawdust( part 1);
- wood ash( 2 tbsp. L.);
- superphosphate( 1.5 tbsp.);
- hydrated lime( 10 g.);
- peat( 1 piece).
The processed box is filled with substrate to the brim. It is preferable to use snow for moistening, laying a layer out of it for gradual thawing. If this is not possible, then you can get by repeatedly spraying. Do not pour prepared containers with plenty of water.
Before sowing, seeds must be trained, which includes soaking for the purpose of decontamination, treatment with growth stimulants, germination in a damp cloth.
The seed embedding depth is 0.5 cm, the spacing between the grains is 2x5 cm. You can sprinkle the top with the same mixture of soil with which the box is filled, but you do not need to overdo it. The upper part of the container is covered with glass or film. Before the emergence of shoots above the ground, the temperature should be within + 22 ° C. It is also important to provide good illumination for sowing.
Growing tomato seedlings at home
For the seedlings to grow healthy and strong, you need to create the right conditions.
Shoots appear about a week after sowing. The box must be installed in a well-lit place. If it is a windowsill, then it is the brightest. With a lack of sunlight, fluorescent lamps are installed. The best development of seedlings can be achieved with round-the-clock highlighting of the shoots that have appeared in the first 2-3 days, after which you can switch to a normal daylight mode - 16 hours.
Young shoots should receive a sufficient amount of moisture, overdrying of the soil is unacceptable. At the germination stage, the moisture regime is maintained thanks to a shelter made of glass or plastic film. You do not need to clean it immediately after the emergence of shoots; you can periodically open the container, allowing the shoots to adapt to the new environment. After 1-2 weeks of this regime, the covering material is completely removed.
With the growth of shoots and an increase in the temperature regime of irrigation, more is required, the soil begins to absorb water more intensively during irrigation. Moisturize seedlings better at the root, without touching the green part. Water should be warm( + 22 ° C), settled.
. Top dressing
.It is appropriate to enrich the soil with nutrients after the leaf has formed on the seedling. Nitrogen-containing fertilizers that stimulate green growth are commonly used. It is important in this matter not to overdo it so as not to burn out the crops. On a bucket of water enough to dissolve a tablespoon of urea.
The second supplement is administered after a week. Best of all at this stage is suitable nitrophoska( for 1 liter of water a tablespoon of money).This procedure is carried out every 10 days.
The grown-up tomato seedlings in boxes need a pick. Its essence lies in seating the shoots in separate pots( plastic cups can be used). The time to transplant usually occurs one month after the sprout appears above the ground surface. Prepared small containers should have a hole in the bottom to allow excess moisture to exit. The lower part of the pot is filled with drainage( small clay or large river sand).Then fall asleep light fertile soil or universal substrate.
Before picking, the box with the seedlings is watered abundantly so as not to harm the shoots during extraction. When transferring a seedling to a separate container, it is worth pinching the root. For 2-3 days after the picking, it is necessary to raise the temperature by a few degrees, so that the plants will soon take root in the new conditions.
