Vegetable plant crop rotation is done by following the principle of growing specific vegetable groups each year on different plots. In other words, a vegetable plot growing vegetables from group A in this year has to be utilised to grow vegetables from other vegetable group the next year. It’s a fairly simple concept once you begin.
Crop rotation is done to ensure that the pests which grow on a particular crop are reduced in number.
Also, it ensures that particular plant diseases will also not develop as a result of poor vegetable plant crop rotation. This method also helps in organising vegetable crops according to their optimum cultivation requirements. This method is suitable for all vegetable gardens. If the garden is too small in size, this rotation might prove to be a problem but a more relaxed version can be done even in the smallest area.
It is better to plan this rotation at the time when seeds are ordered. It is an easy to do crop rotation but crop rotation only applies to annuals, not garden perennials. Asparagus, rhubarb or other perennial vegetables are not suitable for rotation. There are other vegetables which can be grown wherever it is suitable although it is still advisable to not grow them every year in the same place. Pumpkins, cucumbers, French beans, salads and runner beans all fall in this category.
There are many benefits of crop rotation. The first and foremost is the fact that soil in this case remains fertile. The requirements of nutrients in each case is different, thus the soil can enrich and even out itself over time with regard to nutrients. Another benefit of crop rotation is that some of the plants help in controlling weed growth. By rotation, the crops which produce thick foliage (potatoes for example) keep the weed growth under close check.
As a result, many common garden problems remains under check subsequent years. Rotation of vegetable crops is essential for long term gardening success.
Vegetable crop rotation can be done by dividing the ground area into sections, and deciding which part will grow which of the crops. The selection initially is made on how much of each crop is to be grown and what their optimum requirements are. Vegetable crops should be grouped into brassicas, legumes, onions, potato family and roots.
- Brassicas include cabbage, radish and turnips.
- Legumes include peas and beans
- Onions include garlic and onion .
- The potato family includes tomatoes and aubergine along with potato.
- Roots include carrots, celery and beetroot.
