Growing Coral Bells in Your Garden

Coral bells (Heuchera) are a perfect choice for shade gardens, either planted in beds or even in containers. The delicate blossoms make lovely cut flowers or filler for bouquets and also attract hummingbirds. Add in the fact that it's a low-maintenance plant, and coral bells are definitely plants worth growing.

Where to Plant Coral Bells: Light and Soil Requirements

Coral bells should be planted 12 to 18 inches apart depending on the cultivar. They can be planted in spring or fall, and most cultivars are hardy in Zones 3 through 8.

Heuchera grows best in full sun to partial shade. Some cultivars require more shade than others, so you'll want to double-check the exact needs of the one you're planting.

It will thrive in rich, moist, well-drained soil. However, it will also tolerate clay soils, especially if you amend the planting soil with some compost to loosen it up a bit. It grows best in neutral to acidic soil, which covers most soil types.

Plant coral bells 12 to 18 inches apart in spring or fall. Most types have a mounded form 12 inches tall with the airy flower stalks reaching another 12 to 24 inches.

Watering and Fertilizing

Coral bells like consistently moist soil. Plants that have been growing in the garden for a few seasons and are established can withstand short droughts, but they really do best with about an inch of water per week.

If you're growing coral bells in full sun, they'll likely need more water than if they're grown in shade.

Coral bells really don't need much in the way of supplemental fertilizer. Side dress the plants with fresh compost in spring and fall, and that's all they should need.

Pruning Coral Bells

Coral bells is a very low-maintenance plant. The only pruning you'll need to do is to remove the spent flower stalks after blooming, since doing this will often result in a second round of blooms.

Other than that, just pinch off any browning or discolored leaves to keep the plant looking tidy.

Coral Bells Pests and Diseases

True to its low-maintenance nature, coral bells really doesn't have many pest or disease issues.

  • Powdery mildew can be a problem if they're planted in spots that don't get good air circulation.
  • Rarely, the plants can be affected with rust, which causes sunken or raised dark spots on the upper sides of the leaves. Eventually, the center of the spot falls out, leaving a hole. The best way to treat rust is to remove any affected leaves as soon as you notice them (dispose of them, don't add them to your compost pile). If your plant seems to be overwhelmed with it, you can treat the plant with a fungicide. Rust is often caused by poor air circulation and can be exacerbated by the use of high-nitrogen fertilizer, which causes a flush of lush, green, tender growth and can inhibit air circulation as well.
  • As far as pests, very rarely, coral bells suffer from vine weevil damage. They eat the roots and leaves of the plant. You can place some cardboard on the ground nearby and lift it in the morning; often, the weevils will be on the underside of the cardboard. Dispose of it, and repeat daily until you start getting fewer weevils. You can also apply certain nematodes, such as Heterorhabditis megidis and Steinernema kraussei.

Propagating Coral Bells

Coral bells are pretty easy to propagate, and there are two methods you can use.

  • Dividing the plants every three years or so and replanting the divisions elsewhere will give you new plants with very little effort. Plus, this keeps your coral bells growing happily; older heuchera tend to look less lush, and the crown of the plant starts pushing up out of the ground after a few years. Dividing will reinvigorate them. It's best to divide coral bells in the fall, give them a side dressing of compost, and then mulch them well.
  • You can also grow coral bells pretty easily from seed. Sow the seeds indoors under lights in late winter, or sow them directly in the garden after danger of frost has passed.
