Alternation of flower crops
Apr 16, 2018
When planting the same crops in one place, their degeneration is observed: diseases spread, the soil is unilaterally depleted, and other negative changes occur. But the set of flower crops is so great that it is possible to alternate them, choosing various options, and to avoid unpleasant consequences.
For proper planning, the following factors are taken into account: the belonging of plants to certain families, the length of their life cycle( one-, two- or perennials), affection for certain diseases and pests. It is advisable to alternate crops: perennials are replaced by one- or biennials, and then by bulbs, after which you can again plant perennials. Peony, phlox, iris, oriental poppy, aconite, as-tilba, daylily, delphinium and other perennial crops, which annually produce a powerful green mass and are abundantly flowering, over the years severely deplete soil and litter with perennial weeds, so after their excavation is necessary for 2years to dig deeply the soil and choose the roots of perennial weeds, such as dandelion, horse sorrel, especially rhizome, root-sprouts-sow-grass and wheatgrass.
In the first year after the excavation of perennials it is better to plant annuals, for which large doses of organic fertilizers are not applied, but mainly mineral ones. After harvesting the florets, the soil is again deeply digged, roots and rhizomes of weeds are selected, and then large doses of organic fertilizers are applied to the annually excavated bulbs. Quickly grows daylily. It must be divided every 3-4 years. After digging the soil and applying compost and mineral fertilizers, the daylily can be planted in the same place.
Roses are planted for 12-15 years, replacing dead, poorly flowering or old bushes with young ones. However, when dangerous diseases( eg, bacterial cancers) appear, they should be moved to another place by updating the planting material.
Annual and biennial crops can also be sown or planted with seedlings in the same place, alternating them by year. The most common annuals can be planted in the following order: in the first year - astra, on the second - cloves, on the third - sweet peas, then - lemon, calendula, snapdragon, marigold, nasturtium, zinnia, escholium and again astru. Any one- or two-year culture should not be planted in place before 5 years from now.
It is very important to plan and plan the culture turnover of flower crops in advance. This will facilitate the work in the flower garden and will avoid many difficulties and mistakes.
