How do you prepare allium for winter?
Steps To Care For Alliums in Winter Step 1 – Leaves should be left to die back naturally. The earlier-blooming alliums may already be dormant before late fall. Late-blooming alliums should be cut back after the first frost. Step 2 – Move pots to a protected area during winter. After Alliums finish blooming, let the leaves die back naturally, so the bulbs can store energy for the following season. Once the foliage has completely withered, and you have dried flower heads, you can cut it down to ground level. Leave the bulbs in the soil over the winter, as they’ll stay dormant until spring.Some allium species spread vigorously through seeds or multiplication, but many varieties do not spread at all. The allium bulbs that do multiply should be divided every three to four years, simply dig around the plant with a trowel and lift the bulbs out.Allium bulbs come in a wide range of sizes, some are as small as peas and others are bigger than baseballs. The size of the bulb determines the planting depth, they should be planted around 1-2 times as deep as the bulb is high. Plant the bulbs with the pointed side facing upwards.Leave alliums alone when they finish flowering “The leaves die back to nourish the bulb and the seedheads dry out gradually to look very architectural, particularly when frosted.
