mountain laurel

Mountain laurel (Kalmia latifolia 'Sarah') should be watered frequently, but allow the soil to dry slightly between waterings. During the first growing season, water once or twice a week, making sure the soil is moist, but not saturated. When the temperatures are warmer, the plant may need to be watered 3-4 times a week. After the first year, water only when the soil has dried out. Be sure to monitor the moisture level in the soil. Too much or too little water can damage the plant. If the leaves start to yellow, increase watering, but if it is over-watered, the leaves may start to turn brown.

Mountain laurel prefers dappled or morning sun, with the bright morning light being beneficial for promoting flowering in Sarah varieties. It can tolerate some afternoon sun in warmer climates but should generally have shade in the hottest part of the day. Generally, Mountain laurel needs between 4-5 hours of direct sunlight a day. In regions with hot summers, morning sun is ideal. In cooler climates, it can tolerate up to 6-8 hours of direct sunlight.

Mountain laurel (Kalmia latifolia 'Sarah') should be pruned in late winter or early spring when the plant is dormant. Pruning in early summer or fall is not recommended as it may remove flower buds resulting in a sparse display the following spring. Pruning in midsummer can encourage fungal diseases. Pruning should be light and judicious with an emphasis on removing dead branches, suckers, crossing branches, and crossing stems from multiple trunks. Avoid pruning back into older wood as this can severely damage the plant and delay flowering. Avoid topping the plant as this promotes weak and leggy growth. Instead, selectively remove 1-third of the total branches each year over a 3 year period if the shrub is overgrown.
