Growing Guides: How to grow Allium bulbs

Growing Allium Bulbs

Allium bulbs are definite winter growers. Alliums need a sunny position in well-drained soil where the bulbs can be allowed to dry out in the summer months. In areas with damp summers, you can lift the bulbs in summer and grow them either in a bulb frame or in pots so that they can dry out.

Alliums are mostly very hardy and easy to grow. 

Growing and Planting Alliums:

Planting allium bulbs

1. In the Fall, choose a spot that is somewhat sunny and has nicely well-draining soil.

2. Planting allium bulbs is fairly simple. Bulbs look much like a small onion, with wiry roots growing out of one site and a spike on the other. Plant with the roots pointing down and the spike pointing up.

3. Follow the rule of thumb when planting bulbs and give the bulbs at least 2 times their height of soil above them. Dig a 3-4 inch deep hole, drop the bulb into it and cover with soil.

4. Regarding the spacing between bulbs, if planting in beds, leave approx 3 inches between each cluster of bulb. If you are planting in containers, you can space them a little closer together.

5. After planting, water well so that the soil above the bulbs settles.

6. Allium bulbs will begin to flower in the late Spring. After the flowers die down, the plant can enjoy a warmer rest period. You don't have to water too much during this rest period. Leaves will also die back and at this point, you can choose to tidy up the plant and remove the old leaves or just let nature take its own course.
