Everyone loves to eat tomatoes, not just children with a taste for tomato sauce and ketchup. However, grown-ups are more demanding of tomatoes: they should taste like tomatoes, not colored water.
Finding such tomatoes commercially is still difficult. As a result, more and more recreational gardeners are starting to grow their own tomatoes. A very worthwhile undertaking, if you pay attention to the right dates for tomato sowing and use the right soil:
The right soil for your tomatoes
If you grow tomatoes from seed, there is a lot of discussion as to whether to use special seed soil or simple garden soil for this cultivation.
The following arguments apply to the seedling soil:
- It contains no fertilizer that could burn the fine roots of the seedlings.
- It is fairly free of germs, which should reduce the risk of mold growth in the seed tank.
- In the low-nutrient potting soil, the seedlings have to work harder to get nutrients, which should form more and stronger roots.
These arguments for the cultivation soil also apply to other plant substances, eg. For perlite or cocoshum. Perlite and Kokoshum have other advantages: Perlite cultivation is very clean and the substrate can be reused every season. Both substrates actually do not allow fungi to form and the roots of the young plants are easily removed without causing root damage during pitting. However, there are tomato growers who report that the seeds in a too light and loose substrate had problems scraping off the seed coat.
Therefore, the use of normal garden soil or even compost is already recommended for cultivation:
- This is the earth where tomatoes grow later, there is no reason why the seeds should not cope with this earth. But there are many reasons why one should not use an artificially sterilized cultivation soil that could disturb the balance of soil organisms.
- If the seedling has consumed the nutrients present in the seed, it can fall back on the nutrients in the soil, while fertilizer must be fertilized in between using the seedling, whereby the correct dosage is very difficult to find.
- Even in normal garden soil tomatoes would form strong roots, you just have to know how to make them. If the tomatoes z. B. would be kept pretty cool and would not be spoiled with water, they would have to make an effort and develop magnificent roots.
- When the tomatoes are sown in cheap soil, the tomato grower can make it easy and immediately put the seeds in larger pots, in which the tomatoes remain until they are planted outdoors.
- The use of soil or compost makes it possible to raise the tomatoes exclusively with organic fertilizer, without synthetic fertilizer (not least a matter of taste).
- A tomato sowing in normal soil is thus readily possible and also preferable for recreational gardeners with the necessary expertise, since the entire garden benefits from plants that are cultivated without artificially modified soil and without synthetic fertilizers.
If you are going to sow your tomatoes in the heated greenhouse or on the windowsill for preculture, you should do so at the end of February at the earliest. In the unheated greenhouse, the seed can be planted in the middle of March; direct sowing in the garden bed should not take place before the end of March. For tomatoes sown before these dates often suffer from lack of light later, then form long and easily breaking stems with tiny and very bright leaves (the tomatoes "vergeilen"). You will use vigorous and compact young plants with timely flower buds when the location is bright enough and when you place the tiny tomatoes over and over again as soon as there are warm hours during the day. Until the tomatoes are in the garden, they are fertilized with restraint, with little nitrogen.
Put tomatoes in the field
If your reared seedlings are so far off, they will be planted outdoors in a humus rich, well drained soil that has been vigorously fertilized. For this purpose, the tomatoes should have already set flowers as described above, in any case, the planting should take place only after the Eisheiligen.
This soil should be quite calcareous and moist, but loose, the location should provide plenty of sun to the tomatoes, but not expose them to the burning heat. Tomatoes stick their roots deeper than one meter into the ground, so they should have been loosened at least two spades deep. You can support the growth of your tomatoes by planting some stinging nettles under the roots.The upper part of the tomato should be very carefully bent up and tied up.
If you pile the tomatoes about 10 cm high in early summer, they form more roots and can absorb more nutrients. In grafted tomatoes, this is done with soil, naturally growing tomatoes can be piled with a thick mulch layer.
The starvationers continue to need plenty of nutrients, so they are each fertilized more strongly after the beginning of flowering and after the fruit set. What the optimum fertilization of the tomatoes looks like is another topic that is the topic of many discussions.
