Mountain Laurel

Mountain laurel should be kept moist during the summer months, but does not require a huge amount of water. During periods of drought, the plant can survive, but will require supplemental watering. During the winter, when the plant is dormant, water should be reduced to once a month during periods of dormancy.

The Mountain Laurel does best in full sun to partial shade, however can tolerate full shade. It prefers moist, well-drained soil and does not do well in dry soils. Avoid exposing plants to strong winds and shady conditions or it may become leggy or require frequent pruning.

Mountain laurel can thrive in a variety of temperatures, from -30°F/-34.4°C in the Himalayan region to 80°F/26.7°C in Florida, the Carolinas and Georgia. In areas of extreme cold temperatures, a layer of mulch can help to protect the roots. This plant does not tolerate high temperatures well. The ideal temperature range is between 60°F/ 15.6°C-70°F/ 21.1°C.

Mountain Laurel prefers a humid environment, such as one found in areas located near water, coastal areas and shady valleys. It needs a minimum of 60% humidity for optimal growth and greatest flowering. For areas that are too dry, frequent misting with a spray of water from a garden hose or a humidifier can help raise the humidity levels and make the plant more comfortable.

Mountain laurel prefers soil that is slightly acidic, with a pH of around 4.5 to 7.0. The preferred soil type is loam or a combination of loam and sand. It’s best to ensure the soil is kept moist but not soggy. Also, make sure it has good drainage to prevent root rot.

Mountain laurel can be fertilized with an all-purpose 10-10-10 fertilizer or an organic fertilizer, once per year in the spring. Synthetic fertilizers should only be used if the organic fertilizer does not provide the desired results. Several light applications throughout the growing season may also help. The recommended application rate is one tablespoon of fertilizer per gallon of soil. Do not apply fertilizer too close to the trunk of the tree, as this can cause root burn.

Mountain Laurel is generally disease and pest free, however, some common pests that can occur are aphids, spider mites, thrips, and scale. If pest population levels become overwhelming, it is best to remove the affected foliage with a soft cloth or by manually shaking it off. Mild insecticidal soap or neem oil may be applied to the leaves to reduce the insect population. If severe, then a professional insecticide may be necessary.

Mountain Laurel plants should be repotted every three to four years. When repotting, select a pot with good drainage and make sure the soil is of suitable quality. Ensure the pot is just slightly larger than the root ball (around one to two inches). Also, use a well-draining, organic-based potting mix to provide the best environment for root growth.

Mountain laurel can be pruned for shape and size. It's best to prune during the late winter/early spring while the plant is still in a dormant state. It's ideal for the branches to be pruned at a 45-degree angle that is just above a lateral branch to allow room for regrowth. Prune away branches that crowd the center of the plant or those that do not display healthy foliage to keep it looking attractive.

Mulching helps protect the soil and plant’s roots from weeds, evaporation, and temperature flux. The best type of mulch for the Mountain Laurel is a 2-4 inch layer of organic mulch. Mulching should be done several weeks after the last frost.

Mountain Laurel can be propagated by seed, layering, or cuttings. Seeds should be collected in the fall and stored in a cool, dry place. Cuttings can be taken in the spring and air-layered following the same procedure for cutting propagation. Layering can be done in the spring or fall.

Due to the size of the Mountain Laurel, it may require extra support such as a stake or tree support. Staking can be done when the plants are young, before the tree can carry its own weight. Trees should be staked firmly and not too loosely.

Mountain Laurel is considered to be a long-blooming evergreen, producing beautiful flowers during late spring and early summer, and colorful foliage all year round. However, the plant will require a few months of rest in order to replenish the energy reserves. During its rest period, the Mountain Laurel will stop producing new flowers and leaves until the following growing season.

Mountain Laurel is toxic to pets, and humans, if ingested. Symptoms of poisoning can range from nausea and vomiting to seizures and kidney failure. Pets should therefore be kept away from the plant at all times.
