Traditionally, the crop rotation of plants is selected for vegetables and herbs. But in an ornamental garden, it would be good to think about the rules for changing plants in time. You should be especially careful with annual flowers, because many of the beloved flowering annuals are quite capricious. The rules for the selection of previous and subsequent crops for annual flowers are very simple and are based mainly on the relationship of plants. Observing them in practice is much easier than in the case of vegetables in the beds.

Factors determining the annual crop rotation

For ornamental plants, the rules of crop rotation - intelligent alternation, neighborhood and separation of plants - are not built according to the same laws as for vegetable crops. In a vegetable garden, rotation is often critical and its principles, laws and guidelines are some of the strictest. With flower beds, everything is somewhat different.

For all ornamental annuals, the crop rotation is designed to eliminate two major problems:

  1. the risk of cross-pollination, loss of varietal purity;
  2. the spread of pests and diseases.

In this case, the first factor is important only when collecting their own seeds, self-sowing or breeding experiments. Plant health is the main reason for strict adherence to crop rotation. Sowing the same summer plants in the same place, and repeated planting of summer plants in one soil without interruption for many years, can lead to such an accumulation of pathogenic elements that young plants will not survive. The loss of crops and plantings, the degeneration of a favorite variety or species - the risk is too great to be ignored.

For any annuals, the crop rotation is easy to "calculate": unlike vegetables, the alternation of plants is determined by fairly obvious parameters:

  • belonging to the same family;
  • resistance or instability to diseases and pests.

Any "similarities" and similarities are a reason to separate the plants and not plant them one after another in the same place. Conversely, discrepancies in any characteristic allow plants to be used as precursors for more capricious species or after them.

If you want to avoid problems with the spread of pests and diseases, always seek the maximum disclosure of varietal characteristics, for any summer, with the exception of "orderlies" and legumes, it is worth adhering to the general rule - return them to the same place again no earlier than 5 years later. In this case, one can either repeat the same "five-year" scheme, or change cultures arbitrarily.

In order not to get confused in the order of disembarkation, it is worth keeping records for individual flower beds, beds and other planting sites. Annual plans and short notes on the results will help you avoid mistakes in the rotation of annual flowers. It is especially difficult to remember all the details and sequence for large flower beds with a large number of species. For long-term planning and quick sketching, such summer crop rotation diaries are the best helpers.

Basic strategies for crop rotation of annual flowers

There are three main strategies for organizing crop rotation for annual flowers:

  1. Alternation of annuals - replacement of capricious species by nursery plants or species enriching the soil with nitrogen.
  2. Alternation of annuals with perennial, biennial or bulbous plants.
  3. Change of summer season for vegetables, herbs, herbs or green manure.

If traditional crop rotation strategies are not suitable or the soil is severely depleted, needs to be improved or improved texture, the soil after the summer can be left "fallow" for a whole year with herbicides, biological products, organic and mineral fertilizers, soil-forming fertilizers and repeated cultivation.

Ideal "changers" for capricious annual flowers

Most famous for their sensitivity to planting and planting seedlings in the same place are garden asters. Every experienced gardener knows that these beautiful annual flowers need to be constantly moved around the garden. Without crop rotation, asters become extremely vulnerable to fusarium, and the entire collection of varieties can be lost already at the budding stage.

Asters do not return to their original place for 5-6 (or more) years, they are often replaced by carnations (in the "scheme" then you can sow sweet peas, levkoy, calendula, snapdragons), marigolds (nasturtium, zinnia, escholzia).

But not only asters need replacements. Godezia, balsams, verbena, lobelia - these are just a few species for which the crop rotation is strictly observed.

Ideal candidates for alternation with any plant are easy to identify. Among the huge assortment of summer gardens, there are unique plants that can be used to alternate with more capricious species and improve the soil and organize the correct crop rotation on summer flower beds.

Soil "orderlies" suppress pathogens and spores, make the soil healthier, improve microflora and activate the biological environment. They are usually planted before and after other plants, literally interspersed with their favorite annuals.

Summer attendants include:

  • escholzia;
  • nasturtium;
  • marigold;
  • dahlias;
  • calendula;
  • annual phlox;
  • zinnia;
  • petunia.

A special group is made up of ornamental plants from the legume family, which can be equated in their effect with green manure, which enriches the soil with nitrogen. Fire beans, sweet peas, annual lupins are rightly considered universal species for alternation, and they can be included in a crop rotation with any plants. They are especially effective on poor soil.

Perennial, biennial and other alternatives to the alternation of annuals

The replacement of herbaceous perennials with annuals and vice versa can be called crop rotation only conditionally. The most capricious and rapidly degenerating perennials, for example, carpet phlox, fescue or heuchera, require division with a frequency of 2-3 years. In place of the separated plants, you can safely plant any annuals for one year, then replacing them with more permanent plants.

Biennials can also be included in the crop rotation with annuals. They perfectly alternate with both nursery plants and moody flowers like asters. Turkish carnations, pansies, foxgloves, daisies, lunar, forget-me-nots - without exception, all biennial species will do. True, it is impractical to use them alone because of the empty areas.

Seedlings of pansies & Co. are used with bulbs requiring annual digging after flowering, for example, varietal tulips. By planting tulips in autumn, and biennial seedlings in May, you can effectively use the entire available area. Both biennials and bulbous ones can be used as separate, uncombined species for alternation with capricious annuals.

Any annual flowers perfectly alternate with annual vegetables. The principle of the opposite works here: vegetables perfectly alternate with summer attendants, and any summer attendants - with vegetable plantings. You can also plant your favorite salads, radishes, greens for the table on areas that are empty after annual flowers. Legumes and leafy vegetables have the greatest impact on the soil.

Once you've decided to let the soil rest, you don't have to resort to the empty flower garden strategy. In place of the summer people, green manures can be sown several times per season - from mustard and lupine to oats and rye, which will make it possible to achieve a cardinal improvement in the quality of the soil in a year.

Areas after infected plants require special attention

If any letniki were affected by pests or diseases, it is worth planning planting for the next year only with nurse crops. They contribute to the improvement of the soil by releasing phytoncides. You can, in general, leave the site empty to improve the soil.

In place of crops affected by fusarium, it is better not to plant any annual species prone to this disease, primarily asters. Reliably protected by an amazingly dense cover, Fusarium spores persist in the soil, despite any frosts, for 4-5 years.

In a favorable "environment" they infect new plants through the roots. Infection is not so easy to notice at first: the longitudinal stripes at the base of the stems only after some time are "supplemented" by yellowing and twisting of the lower leaves.
