Just remember that there is only one time of the year when you can plant alliums and that is autumn. Allium bulbs are planted to a depth equal to their height. For 1 square meter, you need about 50 large and medium bulbs and about 100 pieces of small ones. After planting, the soil is well mulched with humus or peat and watered well.
Even the most crowded gardens can house multiple alliums because they don’t take up much space. Check these beautiful species if you want to add something new to your garden: Allium Millenium, Allium Unifolium Eros, Allium Red Mohican, Allium Nigru, and Allium Neapolitanum. Don’t forget to cover Allium stems with other plants.
