How do I sow tomato seeds? How to grow tomatoes?
It is best to pre-sow tomato seeds indoors in a propagator in February-April. Sow the tomato seeds in moist soil about 2 cm apart. Cover the seeds with a thin layer of seed soil (maximum 1/2 cm) and spray the soil with a plant sprayer. Use a lid on the propagator so that the soil does not dry out and the temperature does not drop too much, especially at night. Place the propagator in a warm, light spot, because tomato seeds only germinate at a constant temperature of 20-25 ° C.
After 1-2 weeks, the first tomato seeds will germinate. When the seedlings have about 2 real tomato leaves (not the germ leaves) you can transplant the seedlings into separate pots. Be careful, the small plants are still very fragile. Do not use too large pots, as soon as the roots come out of the bottom of the pot, you can repot the seedlings again.
Start hardening off the tomato plants in May by placing them outside in a sunny sheltered place for 2 weeks during the day. As soon as the chance of night frost has passed, you can transplant the plants directly into the ground or grow them further in large pots. Provide adequate support with the help of bamboo sticks. Regularly remove the suckers in the armpits, so-called thieves. In addition, remove the top from the tomato plant at the desired height, usually after the 4th or 5th truss.
