Temperature
The ideal temperature for Heuchera flabellifolia Rydb. var. subsecta Rosendahl, Butters & Lakela, falls between 60°F to 75°F (15°C to 24°C). The plant can withstand some frost, but freezing temperatures can quickly harm or kill it. Protective measures, such as a layer of mulch, can be taken to prevent damage from cold weather.
Soil
Heuchera flabellifolia Rydb. var. subsecta Rosendahl, Butters & Lakela, prefers well-drained soils with a slightly acidic to neutral pH between 5.5 and 7.0. This plant species can also tolerate slightly alkaline soils with a pH up to 7.5. It is not well-suited for heavy clay soils, but can grow well in loamy or sandy soils with good drainage. The addition of organic matter, such as compost, to the soil can aid in water retention and nutrient availability.
Cultivation
Heuchera flabellifolia Rydb. var. subsecta Rosendahl, Butters & Lakela is a hardy evergreen perennial plant that can thrive in a variety of soil types, including clay, loam, and sandy soils. It prefers slightly acidic to neutral soil pH, with a range of 5.5 to 7.0. The plant enjoys full sun to partial shade exposure and needs well-draining soil to avoid waterlogging.
Plant the Heuchera flabellifolia Rydb. var. subsecta Rosendahl, Butters & Lakela in spring after the last frost or in fall. The plant reproduces through seeds and root division, making it easy to propagate. Dig a hole half the width of the root ball, place it in the hole, and refill the hole with topsoil. Space the plant about 18 to 24 inches apart to provide enough room for growth and airflow.
Watering Needs
Heuchera flabellifolia Rydb. var. subsecta Rosendahl, Butters & Lakela requires adequate moisture to thrive. Ensure that the soil is consistently moist but not waterlogged. During the growing season, water deeply once a week, especially during dry spells. Watering in the morning helps prevent fungal diseases caused by moist foliage, especially in humid regions.
Reduce watering during the dormant season and avoid overhead watering to prevent the plant's crown from rotting.
Fertilization
The Heuchera flabellifolia Rydb. var. subsecta Rosendahl, Butters & Lakela is not a heavy feeder. A light application of chemical or organic fertilizer in early spring and mid-summer is enough. Organic fertilizers like compost, well-rotted manure, or fish emulsion enhance soil fertility and improve plant growth. Follow the manufacturer's guidelines when using chemical fertilizers and avoid over-fertilizing, which leads to leaf burn and stunts growth.
Pruning
Heuchera flabellifolia Rydb. var. subsecta Rosendahl, Butters & Lakela doesn't require much pruning, but it benefits from deadheading to promote more blooms and extend the flowering season. Remove the faded flowers by pinching or cutting them off at the base. Prune back damaged, diseased, or dead foliage to prevent decay and encourage new foliage production. Sterilize pruning tools to avoid spreading diseases.
It is advisable to divide the plant every four to five years to keep it vigorous and prevent overcrowding. Divide the plant in spring or fall, and replant the divisions immediately in well-draining soil.
Propagation of Heuchera Flabellifolia Rydb. Var. Subsecta Rosendahl, Butters & Lakela

Disease and Pest Management for Heuchera flabellifolia
Heuchera flabellifolia, commonly known as fanleaf alumroot, is a hardy perennial herbaceous plant that belongs to Saxifragaceae family. Despite being a tough plant, it can be susceptible to certain pests and diseases, which can negatively impact its growth and development. Here are some common diseases and pests that might affect Heuchera flabellifolia and ways to manage them:
Diseases
1. Powdery Mildew: Powdery mildew is a fungal disease that can cause a white powdery coating on the leaves, stems, and flowers of the plant. It can weaken the plant, reduce its vigor, and affect its overall growth. To manage powdery mildew, avoid overhead watering, give the plant enough space for proper air circulation, remove any infected plant parts, and apply fungicides.
2. Rust: Rust is a fungal disease that can cause orange, brown, or rust-colored spots on the leaves and stems of the plant. It can weaken the plant and reduce its aesthetic appeal. To manage rust, remove any infected plant parts, avoid overhead watering, and apply fungicides.
3. Verticillium Wilt: Verticillium wilt is a fungal disease that can cause yellowing, wilting, and death of the leaves of the plant. It can also cause stunted growth and reduced vigor. There is no cure for verticillium wilt, but you can manage it by removing infected plant parts, planting resistant varieties, and improving soil drainage.
Pests
1. Aphids: Aphids are a common pest that can suck the sap from the leaves, stems, and flowers of the plant. They can weaken the plant, reduce its vigor, and cause deformities in the leaves and flowers. To manage aphids, spray the plant with a strong stream of water, apply insecticidal soap or neem oil, or release beneficial insects like ladybugs and lacewings.
2. Slugs and Snails: Slugs and snails are mollusks that can feed on the leaves, stems, and flowers of the plant. They can leave slime trails and cause irregular holes in the leaves. To manage slugs and snails, hand-pick them off the plant, apply diatomaceous earth around the base of the plant, or use slug and snail baits.
3. Spider Mites: Spider mites are tiny pests that can cause yellowing and browning of the leaves, as well as webs on the plant. They can weaken the plant and reduce its vigor. To manage spider mites, spray the plant with a strong stream of water, apply insecticidal soap or neem oil, or release beneficial insects like predatory mites.
By following these disease and pest management tips, you can ensure that your Heuchera flabellifolia remains healthy and beautiful throughout its growing season.
