Feverfew tolerates transplanting well at various stages of growth, including during flowering. Special cultivation from maiden feverfew seeds may not be required because this species reproduces well by self-seeding. So that the plant does not scatter uncontrollably, after flowering, the stems with dried flowers are cut.
For sowing pyrethrum, self-collected or purchased seeds are used. When collecting your own seeds, it should be borne in mind that varietal characteristics are not preserved in them. Such planting material can grow plants with different shades and sizes of flowers that differ from the original variety..
Growing pyrethrum from seeds
Planting plants through seedlings makes it possible to determine the percentage of their germination, it will help the plant to root better when transplanted into open ground. Seeds of pyrethrum do not require special pre-sowing preparation and are sown dry. In order to prevent the planting from getting thickened, the seeds are mixed with sand..
Planting seeds for seedlings:
- planting containers are filled with fertile soil;
- scatter seeds over the surface and sprinkle 5 cm of soil;
- after planting, the surface is watered or sprayed from a sprayer;
- containers are covered with film or glass, put in a bright place;
- for seed germination, a temperature of + 15 ° С + 18 ° С is required;
- time of emergence of seed shoots 12-14 days;
- after the shoots appear, the shelter is removed;
- a pick is carried out when 2-3 leaves appear.
Seedlings are transplanted into open ground in May. For the cultivation of pyrethrum, sunny or partial shade areas are chosen. In constant shade, the plants will be oppressed, elongated and weakly bloom. The soil, especially for growing rare varieties, requires light, loose, with neutral acidity..
Before transplanting, the seedlings are preliminarily adapted to new conditions by taking them outside. The seedlings are transferred into the prepared holes, without shaking off the earthen ball, so that the plants take root faster.
After transplanting, it is important to shade the plants so that the sun’s rays do not burn the delicate leaves..
Plants can be transplanted immediately to a permanent place or to a temporary one for growing and subsequent transplantation..
Choosing a place for planting pyrethrum, you can get not only a decorative island, but also benefits for garden crops. Growing next to cabbage, feverfew helps to get rid of caterpillars. Planted next to fruit trees, the perennial saves them from aphids and moths.
In a typical summer, feverfew can have enough moisture from precipitation. In the dry season, the plant will need additional watering, otherwise the flowers will become smaller. Watering feverfew should be moderate, without waterlogging the soil..
The plant blooms without additional fertilizing, but if pyrethrum is grown on fertile soil, it shows the best varietal qualities, forms a lush bush.
Long stems of the plant can break off from the wind or heavy rain, so they should be tied up.
Feverfew is not filled with weeds, therefore it does not need constant weeding. The soil around the bushes of plants is loosened after rains or watering so that a crust does not form on the soil surface.
In the fall, all perennials are cut off and covered. But feverfew can overwinter without shelter if it is under a gentle cover in winter..
