When to plant alliums – best time to add ‘beautiful pompom flowers’ to your garden

To plant allium bulbs in your garden, start by digging a hole for each bulb in a neat, evenly spaced row.

According to Gardeners’ World, the hole should be at least four times the depth of the size of the bulb itself – usually at least 15cm deep.

As a general rule, it is better to plant the bulbs too deep rather than too shallow in order to support the tall stems as they grow.

Depending on the weather at the time of planting, you won’t need to water the freshly planted bulls if the soil is already moist with rainwater.

If the climate is unusually mild for autumn, it is best to lightly water the allium bulbs after planting.
