Electric Plum Heuchera, also known as Coral Bells, is a striking perennial known for its vibrant purple foliage and compact growth habit. This guide will provide you with essential information on how to properly plant, grow, and maintain Electric Plum Heuchera in your garden.

Planting and Location

Choosing the Right Spot

Electric Plum Heuchera thrives in partial shade to full sun. However, in hotter climates, it benefits from afternoon shade to prevent leaf scorching. A location with dappled sunlight or morning sun with afternoon shade is ideal.

Soil Requirements

• Prefers well-draining soil rich in organic matter.
• Slightly acidic to neutral soil (pH 5.5–7.0) is best.
• Avoid heavy clay or overly compacted soil, as it can retain too much moisture and cause root rot.

Planting Instructions

1. Dig a hole twice as wide and as deep as the root ball.
2. Amend the soil with compost or organic matter to improve drainage and fertility.
3. Place the plant in the hole so that the crown is level with the soil surface.
4. Fill the hole with soil, gently pressing down to remove air pockets.
5. Water thoroughly to help establish the roots.

Watering and Moisture

Electric Plum Heuchera prefers evenly moist soil but does not tolerate soggy conditions.

Light Requirements

• In cooler climates, Heuchera thrives in full sun.
• In warmer regions, partial shade is preferable, especially in the afternoon.
• Too much direct sun can cause leaf scorch, while too much shade may lead to leggy growth and dull coloration.

Fertilization

• Organic compost or well-rotted manure can also be used to enrich the soil.
• Avoid excessive nitrogen, as it can lead to weak, leggy growth.

Pruning and Maintenance

• Remove spent flower stems to encourage continuous blooming.
• Trim dead or damaged leaves to maintain a tidy appearance.
• In early spring, cut back any winter-damaged foliage to encourage fresh growth.
• Divide overcrowded clumps every 3–4 years to maintain vigor and prevent decline.

Pests and Diseases

Electric Plum Heuchera is relatively resistant to pests and diseases but can occasionally be affected by:

• Aphids: Treat with insecticidal soap or neem oil.
• Slugs and Snails: Use organic slug bait or diatomaceous earth around the plants.
• Powdery Mildew: Ensure good air circulation and avoid overhead watering.
• Crown Rot: Prevent by ensuring proper drainage and avoiding excessive watering.

Winter Care

• In colder regions, apply a layer of mulch around the base to protect roots from freezing.
• Avoid cutting back the foliage in fall, as it can provide winter protection.
• In early spring, remove any dead leaves to allow new growth to emerge.
