Alumroot
Alumroot (Heuchera spp.), also called coral bells, is a popular garden foliage plant with attractive heart or kidney-shaped leaves in shades ranging from deep purple-red to medium green. It produces colorful clusters of bell-like flowers in shades of pink, white, red, and peach, usually in midsummer. This low-growing plant makes a great addition to any garden due to its vibrant foliage and unique texture. It works well in garden beds, along pathways, and in containers.
Alumroot should be watered deeply, but allow the potting mix to dry out a bit in between waterings. When the soil dries out, water until water runs out of the drainage holes. Water again only when the soil begins to feel dry to the touch.
Alumroot is a shade-loving plant and prefers bright, indirect light. Direct sunlight will scorch its leaves. Too little light will cause its leaves to become pale and colorless. A bright east or west window is ideal.
Alumroot prefers temperatures in the range of 65 to 70°F (18–21°C). It cannot tolerate frost or freezing temperatures. In addition, extended periods of very high temperature can cause its foliage to scorch.
Alumroot prefers a slightly elevated humidity level. To increase humidity levels, it is recommended to move pots to bathrooms or kitchens, group plants together, use a mister, or place a humidity tray under the plants containing pebbles and water.
Alumroot prefers a neutral to slightly acidic soil with good drainage. A lightweight, well-draining potting mix is ideal. The soil should also be slightly damp and should not dry out completely between waterings.
Alumroot should be fertilized lightly throughout the growing season using a weak liquid fertilizer. A balanced water-soluble fertilizer can be applied every two weeks from spring through fall, or a slow-release fertilizer can be used at the beginning of the season. It is important to avoid overfertilizing, as this can burn the root system and cause foliage discoloration.
The most common pest problems related to Alumroot are aphids, mealybugs, spider mites, and thrips. To get rid of these pests, it is recommended to use insecticidal soap or neem oil. If using insecticidal soap, it is important to cover the entire plant, including the undersides of the leaves, to ensure that all the bugs are killed. It is also important to spray the plants twice a week for two or three weeks in order to completely eliminate the insects.
Alumroot can be repotted every one to two years in order to ensure that it stays healthy and has access to fresh soil. It is recommended to repot in spring right before the growing season begins. When repotting, make sure to pick a pot that is one size larger than the current pot and use a well-draining, neutral to slightly acidic potting mix.
Alumroot does not require a lot of pruning. However, dead or damaged leaves should be removed as soon as they are noticed. Pruning can also help encourage bushier growth. To prune, simply snip off any branches that are dead or leggy.
Mulching the soil around the Alumroot is beneficial for conserving moisture and keeping weeds at bay. It is recommended to use organic mulch such as wood chips, shredded bark, or compost. This can be spread around the base of the plant.
Alumroot can be easily propagated through root cuttings. To do so, take a cutting from the plant's root system and plant it in a container with well-draining potting mix. Place the container in bright, indirect light and water it regularly. The cutting should develop roots in a couple of weeks.
Alumroot does not require any support. It is a low-growing foliage plant and its foliage grows close to the ground, so a support is not necessary.
Alumroot should be given a rest period during the winter months. During this time, potted plants should be moved to an area with lower light levels and watered much less frequently to prevent root rot. Make sure to keep the soil on the dry side during the winter months.
Alumroot is not toxic to pets. It is a safe plant for cats and dogs.
