A Closer Look at Spring-Flowering Bulbs

Crocus, a genus of perennial, spring-flowering bulbs in the iris family, Iridaceae, are known for their vibrant colors and early appearance in the garden. These low-growing plants with large flowers are popular choices for seasonal ground covers, naturalized plantings, beds, borders, and container plantings.

Understanding the growth cycle of crocus bulbs is crucial to know when to lift them. Crocuses flower in spring, and by late spring to early summer, when their foliage has died back, the corms are dormant and can be safely lifted.

When and How to Lift Your Crocus Bulbs

To ensure the health of your crocus bulbs, it is essential to lift them at the right time. Here are some steps to guide you through the process:

Wait until all the foliage has turned brown and easily pulls free before lifting the bulbs.
Use a clean trowel or spade to carefully dig around the clump, allowing enough space to prevent damage to the corms.
Pull the corms apart and discard any damaged, moldy, or undersized bulbs.
Gently remove soil from the corms, leaving the papery tunics intact.

How to Properly Store Your Crocus Bulbs

After lifting your crocus bulbs, it’s crucial to store them correctly to ensure they remain healthy and viable for the next season. Follow these steps for proper storage:

Place the bulbs in a warm, well-ventilated location to dry for seven to 10 days.
Trim away any remaining foliage and roots and brush off any excess soil.
Optionally dust the corms with a fungicide before storing them in a paper bag.
Store the bag in a cool location with temperatures between 50 and 65°F for up to five months.
Check the corms periodically for signs of decay or mold before planting them.

Understanding Vernalization Needs

For crocus bulbs to flower, they require a chill period of 12 to 14 weeks at temperatures of 45°F or lower. If you are planning to force the bulbs indoors, you may need to cool them in the refrigerator to meet their cold requirements.

When to Plant Your Crocus Bulbs

After properly storing your crocus bulbs, you can plant them outdoors once the soil temperatures have dropped to 60°F or below in the fall. The ideal time for planting is typically from September to November, depending on your region.

When planting, ensure that the corms are in the ground at least six weeks before the first hard frost to allow for strong root growth before winter sets in.

Enjoying Bright, Early Blooms

The vibrant blooms of crocuses are a delightful sight that herald the arrival of spring. By following the steps outlined in this guide, you can ensure that your crocus bulbs are lifted, stored, and planted correctly for a spectacular display of flowers in the coming season.
