What is Mountain Laurel?

Mountain laurel is a flowering broadleaf evergreen shrub native to the eastern United States. It is known for its striking clusters of rose, pink, or white flowers with purple markings that bloom in late May to early June. The plant’s elliptical, glossy leaves and multi-stemmed growth habit make it an attractive choice for shady areas in your garden. While it may be slow-growing, mountain laurel adds about one foot per year, creating a dense and round shape.

Mountain Laurel Care Guide

Taking care of mountain laurel involves paying attention to its light, soil, water, temperature, and humidity requirements. Here are the main care guidelines you should follow to ensure your mountain laurel thrives:

Light

Mountain laurel thrives in part shade but can tolerate full sun. Avoid deep shade as it may reduce flowering and cause leaf spots.
If the leaves turn yellowish in full sun, consider providing some shade for the plant.

Soil

Mountain laurel prefers cool, moist, well-drained, acidic soil with a pH of 5.0 to 5.5.
Avoid planting in heavy clay soils. Consider raised berms or planters with well-draining soil mixes.

Water

Newly planted mountain laurel should be watered every three to four days for the first few weeks.
Once established, water once a week during the first growing season and every two to three weeks in spring and weekly in summer.
Ensure the soil is moist but not soggy. Water deeply until the soil is moist to the touch.

Temperature and Humidity

Mountain laurel does well in warm weather with shaded soil. Avoid high temperatures and dense humidity.
Some cultivars are more tolerant of these conditions.

Fertilizer

Feed mountain laurel with an acid fertilizer in spring to encourage blooming.
Follow the instructions on the fertilizer label for the proper amount.

Pruning

Mountain laurel requires minimal pruning. Remove dead or broken branches any time.
Shape pruning can be done in spring after blooming. Deadhead spent flower clusters.
If the shrub becomes too tall or unruly, cut it back almost to ground level to rejuvenate.

Propagating

Propagate mountain laurel by rooting stem cuttings, which can take up to six months.
Follow proper propagation techniques for successful results.
