Sow tomatoes right
How to sow tomatoes correctly? Many gardeners who do not yet have their own experience, or who want to improve the quality of their seedlings, ask this question every year. Let's figure it out. It is recommended to sow in February only varieties of tall tomatoes and hybrids, and it is better with a dive in pots, then the seedlings are not very stretched.
The best size of the boxes is 30 × 50 cm, height is 8-10 cm, previously they are disinfected with copper sulfate (100 g per 10 liters of water).
5-7 days before sowing, prepare the soil mixture. For the mixture we take 1 part humus, old wood sawdust, soddy ground, add 2 tablespoons of wood-type ash, 1.5 tablespoons of superphosphate, 10 g of hydrated lime and 1 part of peat (if any). The box is filled with soil to the brim. It would be nice to moisten it with snow, laying it on top of the mixture - in the room it will gradually melt.
You can buy ready-made soil mix for tomatoes in the store, but in this case, we advise you to purchase such soil from trusted manufacturers in large stores.
Seeds must be prepared in advance. Tested for germination, and, if necessary, treated with growth stimulants.
On the day of sowing, pour the mixture into a box, level it out and slightly compact, pour it with a solution of copper sulfate to prevent the development of fungal diseases. It would be good to add liquid mullein to the solution (for 8.5 l of water, 3 tablespoons of mullein and 1/2 teaspoon of copper sulfate).
The distance between the seeds when sowing 2 × 5 cm, the depth of planting up to 0.5 cm. Sprinkle on top of the crops with the same mixture, carefully water, close the box with glass or film, put in a warm, bright place (not lower than +22 ° C).
The first shoots appear in a week. Immediately place the box for the next week in a cooler place (up to +18 ° C) so that the seedlings do not stretch. Seedlings can be left in the same place, but at the same time it is necessary to reduce the temperature regime by 7 days with a screen, or with the help of a window leaf.
For 27-30 days after germination, the plants will develop to the second true leaf. Tomato seedlings are watered during this period only two to three times.
The first watering is when all seedlings appear (1 glass of clean water for the entire box). The second watering - after 3 weeks, and the last on the day of diving for 3 hours. Water temperature should be +22 ° С. Water should not fall on the leaves.

Every 6 days, spray the plants with skim milk (1/2 cup milk per 1 liter of water). Such spraying of seedlings, and further spraying of plants planted in the ground, protects the tomatoes from late blight. We begin to spray with the appearance of the first real leaflet.
If possible, do not put the box with seedlings on the windowsill, it is better to put it next to the window on the stand and provide additional illumination. This will protect the seedlings from accidental frostbite, if you do not close the window, as well as the earth in the boxes will not dry out from the heat of the batteries.
