How to propagate Allium grandiflorum

Propagation of Allium grandiflorum by division

The division propagation of Allium grandiflorum needs to be carried out in autumn. Generally speaking, the main steps include peeling off the sub-bulbs around the main bulb of Allium grandiflorum around mid-September, and then planting them in sandy soil with low groundwater level, good drainage conditions, and fertile and loose soil. Bulb division propagation, which is basically the same as division propagation, is generally carried out in summer and autumn. The specific steps are to divide a mother bulb into several daughter bulbs, and then plant the larger bulbs.

Seed propagation of Allium grandiflorum

The best time to propagate Allium grandiflorum seeds is in late summer and early autumn. Specifically, after the seeds mature in mid-July, they are collected, dried and stored at low temperatures, and then sown in September or October. In this way, they will germinate in the spring of the following year and form small bulbs in the summer and can be cultivated continuously. In addition, it is important to loosen the soil, water, fertilize, and prune in a timely manner during the growth period of Allium giganteum. Also, it is important to strengthen ventilation and drainage, and pay attention to appropriately increasing the environmental humidity and providing appropriate shading to avoid strong light. In addition, remember not to collect seeds and then cut off the flower stems after flowering, so as to promote the healthy growth of the bulbs. Because as far as the habit of Allium grandiflorum is concerned, it likes cool and sunny places, so there is no need to cover it to protect it from the cold in winter, just increase the light. The bulbs should be dug out in time before the summer rainy season arrives to avoid plant rot after the rain. Also pay attention to applying more mature organic fertilizer and draining water in time.
