Mountain Laurel Plant Care

Mountain Laurel (Kalmia latifolia) belongs to the Ericaceae family within the Kalmia genus. Mountain Laurel is native to the eastern United States. Mountain Laurel is also known as Calico bush, Lambkill, Witch-laurel.

Mountain Laurel displays a compact, mounding shrub growth habit, reaching up to 4 inches tall with a spread of approximately 4 inches. Mountain Laurel produces clusters of small, cup-shaped flowers in shades of pink, white, or purple.

Leaf size: approximately 2 inches.

Kalmia latifolia requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Mountain Laurel thrives in partial shade to full sun light conditions. The optimal light range is 1000–3000 lux. Avoid placing Mountain Laurel in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Kalmia latifolia grows best at temperatures between 0°F and 80°F. Mountain Laurel prefers humidity levels of 40–60%.

Well-draining acidic soil mix with high organic content, such as peat moss and pine bark. Good drainage is essential for Mountain Laurel to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Mountain Laurel can be propagated through seeds, semi-hardwood cuttings.

Mountain Laurel is susceptible to aphids, lace bugs, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
