Growing Alliums should not be a big challenge even for beginners. They are drought-tolerant, resistant to pests, and low on maintenance. They also come in a wide range of variety in terms of heights, blooming period, and form and color of flowers. Alliums are grown from bulbs planted in the fall. Bulbs should be planted at a depth of four times the diameters of bulb. Alliums generally prefer a rich and well-drained soil under sunny conditions. If you are growing them in poor soil, feed them with a general fertilizer in early spring or top up the soil with a layer of compost [Also read: How to prepare your own compost].

Most varieties start blooming from late summer to early summer. Flowers, especially of late blooming verities, last longer. Both fresh and dry flowers make excellent addition to flower arrangements. As end of season approaches, leaves start straggling and should be cut back, if required. Once flowering is over, bulbs can be lifted and stored for the next harvest.
