How to Plant Crocus Bulbs

Crocus bulbs are great additions to your spring garden, contributing a display of small purple, white, and yellow flowers. Crocus are also wonderful pollinators and invite plenty of insects and critters to your beds and borders!

However, if this is your first time planting crocus throughout autumn, then you may feel a bit stuck on where to begin. We’ve written this guide with you in mind, to help you go from bulb to border in just a few easy steps.

When to Plant Your Bulbs

When it comes to spring-flowering bulbs, you should always aim to plant them in early autumn. This gives the bulb time to grow through the winter and appear in spring!
Once you receive your bulbs, get them in the ground as soon as possible. Avoid frosty conditions and plant your crocus bulbs in soil that is warm and well-drained.

Where to Plant Your Bulbs

Where to plant your bulbs depends on the display you would like to achieve. For example, if you’re aiming for a uniform look, plant your bulbs among your beds and borders. If you’d like a more natural look, plant your bulbs informally through grassy areas of the garden.

Crocus bulbs can be planted just about anywhere, as long as they are in full or partial sunlight and have plenty of soil, moisture, and grit for drainage.

How to Plant Your Crocus Bulbs

To plant your bulbs, you should follow these easy steps. First, dig a hole in your desired area that is two to three times the depth of your bulb. Make sure they’re spaced twice the bulbs width apart.
Plant with the pointed tip facing upwards, cover with soil, and water once done.

When to Plant Crocus

The jewel-like tones of Crocus flowers are just one of the many reasons why these plants are loved by gardeners. Autumn crocus add a rainbow of colour to the garden as summer flowers start to fade, and Spring Crocus are one of the earliest plants to flower in late Winter. Since Autumn Crocus and Spring Crocus bloom during different seasons in the year, these corms need to be planted at their correct times. 

Discover exactly when and how to plant Crocus corms and fill your garden with stunning Crocus flowers for most of the year.

What are Crocus corms?

Corms are very similar to bulbs, but corms are specialised sections of the stem. The appearance of corms differs from bulbs as corms tend to have a flattened shape.

When to Plant Autumn Crocus:

The best time to plant autumn-flowering Crocus is late July to September. Plant the corms around 4 inches deep in gritty, well-drained soil. These plants are perfect for pots and borders and will flower from September into November.

Tip – Plant Crocus corms in drifts in grassy areas or around other plants for a naturalistic look.

When to Plant Spring Crocus:
