Heuchera, also known as coral bells, is a popular perennial plant cherished for its vibrant foliage and delicate flowers. Properly storing Heuchera bulbs during the off-season ensures healthy growth and vibrant blooms year after year. In this article, we will explore effective tips and tricks for storing Heuchera bulbs successfully.
Understanding Heuchera Bulbs
Heuchera plants grow from bulbs or crowns that store nutrients needed for regrowth. These bulbs can be sensitive to cold temperatures and moisture, making proper storage crucial during winter or dormant periods. Recognizing the right time to store and the ideal conditions will help prevent rot and damage.
When to Store Heuchera Bulbs
The best time to store Heuchera bulbs is after the plant has finished flowering and the foliage has died back. Typically, this occurs in late fall or early winter, depending on your climate zone. Wait until the soil has cooled and the plant has entered dormancy before removing the bulbs.
Signs of Readiness for Storage
- Foliage has yellowed or withered
- Plant has stopped growing
- Soil has cooled significantly
Steps for Storing Heuchera Bulbs
Follow these steps to ensure your Heuchera bulbs are stored properly:
- Carefully dig around the base of the plant using a garden fork or spade.
- Gently lift the bulbs, avoiding damage to the roots.
- Shake off excess soil and inspect for signs of rot or disease.
- Trim back any remaining foliage to about 1 inch.
- Allow the bulbs to dry in a cool, well-ventilated area for a few days.
Preparing Bulbs for Storage
Once dried, prepare the bulbs for storage:
- Remove any damaged or diseased parts.
- Optional: Dust bulbs with a fungicide to prevent mold.
