Coral Bell (Heuchera) Care Instructions
Carefully remove plants from packaging.
Keep relatively moist until ready to plant, and try to plant within 3 days.
Heuchera Planting Instructions
- Dig hole and loosen the surrounding soil.
- Amend soil if needed (blend nutrient-rich, well-draining soil with existing soil if the soil condition is poor i.e. sand or clay).
- Place plant into hole, keeping the crown above the soil line.
- Gently firm soil around the base of the plant.
- Watering the plant will help it settle into its new home.
- Heucheras prefer shadier locations, although some will tolerate full sun. Search our website for specifications on each variety.
- Morning sun is usually comparatively better than hot afternoon sun.
- Generally, heucheras that are lighter green or white tones prefer shadier locations than orange, gold or purple varieties.
Heucheras in Containers
- Heucheras can be grown in containers with proper drainage.
- Check to make sure that the container has adequate drainage holes.
- Layer the bottom with pottery shards to prevent the drain holes from clogging.
- Fill the pot with a soil mix that does not contain too much peat.
- Containers may need to be watered more during hot/windy periods.
- In cold climates, the potted heuchera will need to be overwintered or covered to protect the shallow roots.
- Overwatering and over-fertilizing can kill a heuchera.
- Heucheras may wilt from too much or not enough water, although it is important not to allow plant to dry out between waterings.
- Sometimes it is difficult to determine the cause of a failing heuchera- the best solution may be to relocate it.
- After flowering, the flower stalks can be removed. This allows more energy to go back into the plant instead of making seed, and encourages rebloom.
- Heucheras located in sunny or windy areas may need to be watered daily in hot weather to look their best.
Heuchera Diseases and Pests
- Heucheras are fairly resistant to diseases.
- Avoiding poor air circulation and poor drainage are two of the best ways to keep your heuchera healthy.
- Heucheras are fairly resilient, so transplanting an ailing plant to a new location may be a better solution than trying to determine the nature of the disease.
- Heucheras are considered to be deer resistant plants. However, that’s not a guarantee that deer won’t eat heucheras.
- Heucheras have low fertilizer requirements
- Before applying fertilizer, wait at least 7 to 10 days after planting.
- A light application of fertilizer is best – err on the side of caution.
- Cease fertilizing by August 1 to allow plants time to shut down for the winter.
o Foliar Feeding:
(Fertilizer mixed with water, absorbed through the leaves and roots)
- Use Peters 20-20-20 or Plantex 20-20-20 fertilizer.
- Mix ½ of the recommended dosage (½ tablespoon per gallon).
- Use 1 tablespoon per gallon after the plant reaches maturity.
- Apply using sprayers, injection sprayers or watering cans.
o Balanced granular fertilizer:
- Use a time release fertilizer like Osmocote twice during the growing season. One application can last a few months.
- When using a granular fertilizer, it is very important not to get it on the foliage as it can burn the leaves.
- Heucheras may need to be divided about every 3-5 years when the center becomes woody and the growth slows down. In some varieties the crown will raise up, requiring it to be reset.
- The best time to divide heucheras is in the spring. That allows your heuchera to recover and develop a strong root system when winter appears.
- Use a sterile tool or trowel to dig up the heuchera and gently pull it apart. Any rosettes should be divided and replanted with the crown at ground level.
- Most heucheras can thrive in zones 4-9.
- Heucheras should be covered with 6 to 12” of mulch after the ground freezes. Keep them covered until the threat of frost has passed.
- In milder climates, heucheras will maintain their color throughout the winter. During the spring, new shoots emerge with their spring coloring.
- The old and damaged foliage and stalks should be removed at this time to prevent disease.
