Heuchera

Heuchera should be watered thoroughly, but rarely. Allow the soil to dry out between waterings, but not to the point that it becomes desiccated. Water deeply, allowing the water to completely saturate the roots. Do not allow the plant to sit in water, as this will quickly lead to root rot. During the winter, reduce watering as the plant enters its dormant season.

Heuchera plants prefer bright, indirect light, either from a south- or west-facing window. If the light levels are too low, the plant will begin to suffer, and its leaves will lose their vibrancy. If you want richer colors and brighter foliage, move your plant to an area that receives more light. However, be sure to keep it from burning by taking occasional breaks or giving it a few hours of shade during the day.

Heuchera plants prefer relatively cool temperatures, typically between 60-70°F (15-21°C). In warmer climates, provide extra humidity to prevent the leaves from becoming dry and brittle. If the air temperature drops too low, the leaves may begin to suffer from frost damage, so be sure to keep them out of direct drafts. During the winter, the plant can survive temperatures as low as 50°F (10°C).

Heuchera plants prefer moderate to high humidity levels, such as those found in bathrooms or kitchens. If the humidity is too low, mist the leaves regularly or use a humidifier. Avoid leaving the plant in direct humidity such as a shower, as it can lead to pests and disease. Also, be sure not to overwater, as this will create an ideal environment for fungus and bacteria.

Heuchera plants prefer a light, well-draining soil. A mixture of equal parts potting soil and expanded clay pellets or perlite works well. If growing in a hydroponic system, a light soilless mix such as coco-coir will work.

Fertilize Heuchera plants once every two weeks during the spring and summer months. For best results, use a balanced liquid fertilizer or a fertilizer specifically designed for use with houseplants. Do not fertilize during the winter, when the plant is in its rest period.

The most common pests that affect Heuchera plants are aphids, spider mites, and mealybugs. These pests suck away at the plant’s sap before leaving behind a sticky residue. A combination of insecticidal soaps and neem oil will help to get rid of the pests. In addition to chemical treatments, another method of deterrence is to introduce beneficial insects into the environment, such as ladybugs or lacewing larvae. These insects will naturally feed on aphids, spider mites, and mealybugs.

Heuchera plants should be repotted every few years when they have out grown their current pots. Choose a pot that is 2-3 inches larger than the existing one and fill it with a well-draining potting mix. Be sure to water thoroughly after repotting to avoid transplant shock.

Heuchera plants do not require much pruning. However, if the foliage becomes too large or overgrown, prune it back with a pair of sharp pruners. Removing dead or diseased foliage is also beneficial, as this will prevent the spread of any fungus or disease.

The soil around Heuchera plants should be mulched to help retain moisture and regulate temperature. A good mulch to use is compost or pine straw, both of which will provide necessary nutrients while discouraging weed growth.

Heuchera plants are propagated from root, stem, or leaf cuttings. Cut a section from the base of the plant and pot it up in moist potting mix. Keep the soil moist and provide bright but indirect light. The cutting should take root within 4-6 weeks.

Heuchera plants will not require any form of support, as they are self-supportive. If you wish to stake the plant, be sure to do so at least one week after repotting.

Heuchera plants enter a period of dormancy in the winter, indicated by their reduced growth rate and paler foliage. During this time, it is important to reduce watering and only provide water when the soil is completely dry. After the weather starts to warm up in the spring, begin irrigating again and the plant will slowly start to return to its former state.

Heuchera is not considered toxic to pets, and is safe for cats and dogs. However, as with all house plants, be sure to keep them out of reach of animals to prevent ingestion.
