Crop rotation of tomatoes or after which you can plant tomatoes for the next year?


Experienced gardeners know that a rich harvest often depends on a properly selected neighborhood of crops grown.

Not all plants are friendly. This adversely affects their life and can provoke wilting. It is very important, among other things, to take into account which predecessors grew in this place last year.

This article describes in detail the crop rotation of tomatoes and tells after which you can plant tomatoes for the next year.

Crop rotation rules for tomatoes

What it is?

Crop rotation is a deliberate alternation of planting different types of plants in a certain place.... The basic rule is that you need to alternate root crops and plants with a fruiting green part.

In fact, the circuit is much more complicated. It is necessary to take into account how developed the root system is, how the plant feeds, what elements it needs, to which family it belongs.

Why is this technique used?

  • To prevent infection with diseases and pests... It is not recommended to plant representatives of the same family on the same garden bed, since diseases of their predecessors are dangerous for such plants. You can kill healthy seedlings if dangerous bacteria, fungi or pests remained in the soil last year. As a preventive measure, insecticidal preparations can be used, but it is better to simply avoid potentially dangerous areas.
  • To preserve soil fertility and even enrich it... Some plants take nutrients from the upper soil and some from the lower soil. There are also some that enrich the land (for example, legumes). There are plants that release toxins. A well-thought-out crop rotation allows you to maintain the necessary balance in the soil.

Outdoor tomatoes should ideally be grown in a new location every year. If you grow tomatoes outdoors, finding the right place will be easier. When using greenhouses, the problem is more acute, but below we will tell you what to do in this case.

What does practice say?

The question, after which it is possible to plant tomatoes for the next year and after which crops it is better not to do this, is not easy.

Let's take a closer look:

  • Is it possible to plant tomatoes after cucumbers and vice versa?

    You should not think about planting tomatoes after cucumbers, because this is a neutral predecessor. Cucumbers belong to the melons family, so their diseases are different from those that affect tomatoes. A convenient option for planting in a greenhouse. You can rotate these crops annually. This category also includes the "close relatives" of cucumbers: pumpkins, zucchini, watermelons, squash, etc. It turns out that the answer to the question of whether it is possible to plant tomatoes after cucumbers is unequivocal - yes.

  • Is it possible to plant tomatoes after onions?

    Yes! The bow is quite a suitable predecessor. Pests and diseases are not terrible for tomatoes. It is also able to heal the soil due to its bactericidal properties, so tomatoes after onions should theoretically be in order.

  • Is it possible to plant tomatoes after peppers?

    The answer to the question of whether to plant tomatoes after pepper is no. Sweet and bitter peppers and tomatoes are relatives. This means that such plantings can adversely affect your harvest. To avoid pests or dangerous diseases, it is better to find another place for your tomatoes. Undesirable predecessors of the nightshade family include the less common ones: eggplant, physalis.

  • Is it possible to plant tomatoes after potatoes?

    Not! Absolutely forbidden. Potatoes are the most unfortunate predecessor, because they belong to the nightshade family, like tomatoes. This means that these plants have similar diseases and pests. Late blight is especially dangerous. Fighting this disease is difficult. Rare varieties of tomatoes are resistant to late blight, therefore, whether it will be good for tomatoes after potatoes - obviously not, and the question of whether to plant tomatoes after potatoes disappears by itself. We strongly advise against taking such risks.

  • Is it possible to plant tomatoes after strawberries?

    Not! Strawberries are extremely soil depleting, literally pumping out all the beneficial elements. Therefore, it is not recommended to plant tomatoes immediately after it. It is better to place green manures, herbs, flowers, onions or garlic in this place. In one season the soil will recover, but in the second year it is quite possible to use the soil for tomatoes.

  • Is it possible to plant tomatoes after a tomato?

    Not! It is undesirable to do so. On the open ground, you can always move the plantings so that their location is optimal. Therefore, it is up to you to decide whether to plant tomatoes after a tomato.

So, we figured out, after which it is impossible and after which it is possible to plant tomatoes, but often the annual planting of tomatoes in one soil is a necessary measure, since tomatoes are usually grown in greenhouses, and it is impossible to transfer the entire structure to a new place annually. What to do in this case?

Tomatoes are highly acidic to the soil and prefer a neutral pH.

  1. To restore acidity and fertility, it is possible to sow green manures at the time of harvesting in the fall. These include:
    • mustard;
    • oil radish;
    • lupine;
    • clover;
    • phacelia;
    • alfalfa;
    • buckwheat;
    • oats;
    • barley.

    Then dig up the ground along with the remains of these plants. They serve as green fertilizer.

  2. If this could not be done at the end of the season, siderates can be sown in the spring and mowed two weeks before the tomato seedlings are planted.
  3. The second option is to add lime (50g per square meter) in the fall and dig it up.
  4. Do not forget about the introduction of nitrogen fertilizers in spring and autumn, also phosphorus and potassium are needed for tomato.
  5. To disinfect the greenhouse - in the spring (there are no plantings yet), you can use a smoke sulfur bomb.

Be careful, the sulfur cup is highly toxic! Do not stay inside the greenhouse while the checker is on fire. Read the instructions carefully and follow the precautions!

It is good to place several marigold, calendula or nasturtium plants in a greenhouse with tomatoes. The smell of these plants drives away many pests. In autumn, they should be crushed and buried in the soil, like ordinary green manure. In this table, for your convenience, plants are presented, after which it is advisable to plant tomatoes and plants that should be categorically avoided if you want to get a good harvest of tomatoes.

Try to follow our recommendations and enjoy a great harvest every year! Remember, if you still do not have the opportunity to allocate a suitable place for tomatoes, siderat herbs will always come to the rescue.
