A practical guide for the cultivation of tomatoes
The fascinating variety of tomatoes opens up to the hobby gardener only when selecting the seeds, in contrast to pre-grown young plants. With this guide you can grow tomato seeds without stumbling blocks.
Sowing behind glass compensates for climate deficit
Located in warm South America, tomatoes in the local regions thrive at the earliest from mid-May. Such a late direct sowing would have no chance of success given the maturity. Therefore, experienced tomato growers will be breeding in protected areas from the beginning / middle of March. As a result, the young plants start the season with a pleasing growth advantage, which offsets the deficit of the climate. How to proceed:
Tomato seeds germinate reliably at a constant temperature of 20-24 degrees Celsius within 10-14 days. The seed preferably spends this phase in the half-shady location, because blazing sunshine would spoil the seedlings. During this time, the substrate and seeds must not dry out under any circumstances. The casting is particularly gentle from below, using the capillary force of the root system.
Seedlings want to be cooler and brighter
If the delicate cotyledons emerge from the seeds, the light requirement of the tropical plants increases. So that the young plants do not hurry immediately, a change of location provides a remedy. Now it may be cooler with 16-18 degrees Celsius, so that the amount of light on the south window is sufficient for further growth.
Correctly isolate with a steady hand
After germination, tomato plants put a lot of effort into it. Within a few days, another pair of leaves thrive. Now it is getting too narrow in the growing vessel, so that the time has come for the singulation. What appears to the beginner, under the name of Pikieren, as a book with seven seals, in truth requires only a steady hand and this guide:
Until planting outdoors or in the greenhouse, keep the tomato plants constantly moist in the warm, bright window seat.
Tips & Tricks
A direct sowing of tomatoes in March or April has only one chance in the heated greenhouse, because only a constant temperature of more than 20 degrees Celsius can animate the seeds to germination. Alternatively, it's worth trying to seed extra early varieties, such as the cherry tomato 'stupice' in mid-May. With a maturity of 52 days, the plan could succeed.
