While they are remarkably resilient in a dormant state and will tolerate waiting, they should be planted a few weeks before the ground freezes. After planting, their roots will form, and you can expect blooms to arrive in late spring or early summer.Ornamental alliums are just about the perfect drought-resistant and low maintenance plant.

What should you not plant near alliums?
Plants Not To Grow With Alliums Avoid planting any type of Allium, ornamental or edible, near beans and peas in the edible kitchen garden. While Alliums are good at attracting beneficial pollinators, they also give off chemicals in the soil that will stunt the growth of any beans or peas growing near them. Slow-release, granular fertilizer is the best type of feed for both edible and ornamental alliums. It will supply nutrients all season long. The edible alliums will benefit from a balanced fertilizer like a 10-10-10 NPK formulation to support strong growth.Specialist alliums, such as Allium insubricum, are best grown in containers or the rock garden so you can give them the care they need more easily.

Can I plant alliums in October?
Plant Allium bulbs in early to mid-autumn in a sheltered site to prevent the top-heavy flower spikes from blowing over. Dig over the soil and remove any weeds before planting. Water well after planting, saturating the soil around the bulbs. Once established, Alliums are drought tolerant. Since ornamental alliums bloom just once a season, there is no way to encourage reblooming by regular deadheading or pruning of the plant. The remaining foliage is often attractive for a few more weeks and can add interest when combined with other perennials that have contrasting or complimentary leaf shapes.Regular deadheading (1-2 times a week) encourages the plants to put their energy into creating continuous growth and more blooms. Deadheading is a simple task, that only requires you to pinch or cut off the flower stem below the spent bloom, and just above the newest set of healthy leaves.
