Vegetables do not like to take root in the same place for a long time since the next year they find the soil too poor for their tastes! This is why it is necessary to replace them with other vegetables which, on the contrary, enrich the soil. At this point the rotation of the vegetables comes into play.
This cultivation technique teaches us to do this, that is, it recommends the order in which the vegetables, belonging to different families and species, must follow one another on the same plot of land over the course of the various seasons.
Rotating vegetables, advantages
The rotation improves the quality and yield of horticultural production, reduces the growth of weeds, combats insects and diseases and protects the fertility of the soil. Consequently, less herbicides, fertilizers and pesticides are needed. In short, a real cure-all for both our garden and our finances.
Rotation of vegetables, the list
Here is a list of the most used species with the relative number of years that we should wait before replanting them in the same place.
- Garlic - 4-5 years
- Asparagus - asparagus remains on the ground for many years, but once it has exhausted its productivity, it will take 7-8 years before repositioning it on the same ground
- Artichoke - an artichoke can be kept on the same plot for 7-8 years, but the ideal is to keep it for about 4 years. The good thing is that it can precede or follow any crop
- Carrot - not earlier than 3 years
- Cauliflower - 2 years
- Cabbage, black cabbage - 2 years
- Cucumber - from 2 to 4 years
- Onion - 3-4 years
- Lettuce - by 2-3 years
- Melon - not earlier than 4 years
- Potato - not earlier than 4 years
- Pea - 3-4 years
- Tomato - the ideal is to rotate it with a legume
- Leek - 3-4 years
- Celery - 3-4 years
- Spinach - not earlier than 3 years
- Pumpkin - 2-3 years
- Zucchini - 2-3 years
Obviously, if you have a small vegetable garden, you will not be able to perform this technique as we have just listed; in that case, however, we will know that the vegetables listed above will need to be rotated at least once a year, if you can then wait for another season even better. If a vegetable has suffered from some disease there will be one more reason to move it and have it followed by a crop belonging to another family. Sometimes a simple alternation between vegetable families may be enough to have some more success.
Rotating vegetables, useful information
- Longer rotations (4-8 years) give better results, but don't forget to always insert legumes inside them: they are the ones that have the most fertilizing properties
- If you opt for a four-year rotation, divide the garden into four particles, where the planned vegetables will alternate
- Start with a legume (example: peas or green beans) then move on to a plant with high nutritional needs, such as the potato, which can greatly benefit from the residual fertility, continue with a slightly less voracious vegetable, such as onion, and finish with an undemanding vegetable such as carrot.
