How to grow decorative onions
When growing the bulbous genus Allium in temperate climates, it is best to dig up the bulbs after the seeds have ripened and the leaves have dried out and replant them in the fall. This is necessary because ephemeral bows are native to the mountains of Central Asia, an area with hot, dry summers and frequent thaws in winter. At home, the bulbs of these species after the end of the growing season, from late June to autumn rains, are in a warm and dry environment. There is practically no precipitation during this period. In our area, the summer can be damp and cool, and the bulbs left in the ground begin to suffer from various diseases, or they can start to rot. Therefore, it is best to dig them up, dry them and put them in a box in a dry ventilated room until autumn. If the summer is dry, you do not need to dig up the bulbs, but when thickened, the onions become smaller and bloom worse.

In autumn, after a steady drop in temperature, the bulbs are planted again. The optimum soil temperature for bulb rooting is 10 ° C. The planting depth of ornamental onions is determined taking into account the size of the bulbs: above its top there should be a layer of earth three times more than the height of the bulb. Accordingly, if the bulbs are large, they are planted much deeper than smaller ones.
