Heuchera Planting Instructions

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.

Lighting Conditions

  • Heucheras prefer shadier locations, though some will tolerate full sun. Search our website for specifications on each variety.
  • Morning sun is usually preferable to 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.

Heuchera Care

  • Overwatering and over-fertilizing can kill a heuchera.
  • Heucheras may wilt from too much or not enough water, though 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, this is not a guarantee that deer will not eat heucheras.

Fertilizing

  • Heucheras have low fertilizer requirements
  • Wait at least 7 to 10 days after planting before applying fertilizer.
  • 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.

Dividing Heuchera

  • 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, allowing the plant to recover and develop a strong root system before winter.
  • The plant should be dug up with a sterile tool or trowel and gently pulled apart. Any rosettes should be divided and replanted with the crown at ground level.

Winter Care

  • Most heucheras can thrive in zones 4-9.
  • Heucheras should be covered with 6 to 12” of mulch after the ground freezes. (Keep covered until the threat of frost has passed).
  • In milder climates, heucheras will maintain their color through the winter. In 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.
