The reason why crocus can't bear seeds

Crocus blooms, but does not bear seeds. The reproduction of saffron depends on bulbs and saffron bulbs, not seeds. Crocus sativus can't produce seeds by itself, so it needs artificial pollination to propagate seeds. Crocus sativus can't produce seeds without pollination.

When planting crocus sativus, we should choose full seeds without any diseases, apply decomposed cake fertilizer and plant ash in the soil to increase the fertility of crocus sativus, then plant the seeds in the soil, and then use nitrogen, phosphorus and potassium compound fertilizer to promote the growth of crocus sativus after germination.

Crocus sativus can be planted in March-April in spring or September-65438+1October in autumn. Autumn is the best season, depending on the weather. When planting crocus, plant the seeds in the soil, and then water them 1-2 times a week, so that crocus can germinate faster. After about 20 days, the saffron will germinate. At this time, you should put it in a sunny place for maintenance.

Brief introduction of crocus

Crocus is also called crocus. Crocus sativus is a subtropical plant, which likes to be warm and cool, afraid of heat and cold. It is best to use fertile sand as soil to avoid water accumulation.

The optimum temperature of crocus sativus is 2-65438 09℃, and it can safely overwinter at the temperature of-65438 08℃ in northern China. Proper shading at the high temperature of 25℃ in the south can prolong the growth time of crocus sativus and benefit the weight gain of crocus sativus bulbs. In western countries, flowers are picked in the wild and bulbs are used for reproduction. In China, flowers are mostly collected indoors and bulbs are propagated in the field. The growth habit and technology of saffron are similar to those of farmer kind of garlic.
