How to Prune Bog laurel?

(Kalmia polifolia)

Bog laurel, also known as Western bog laurel, Box laurel, Swamp laurel

A vibrant inhabitant of wetland areas, bog laurel is distinguished by its glossy evergreen leaves and clusters of pink flowers. Pruning should maintain a natural shape, removing only damaged or diseased wood and spent blooms. Pruning can be done at any time, but optimal results occur when trimming is performed in late winter or early spring before new growth starts. Pruning encourages robust health by enhancing air circulation and can also stimulate new flowering shoots, ensuring bog laurel's ornamental appeal.

What Are the Benefits of Pruning Bog Laurel?

Pruning bog laurel encourages vibrant blooms, invigorates growth, and maintains its compact form. Regular trimming is pivotal for robust health and aesthetic appeal.

What Is the Best Time for Pruning Bog Laurel?

Spring

Summer

Autumn

Winter

Pruning bog laurel during late winter to early spring is ideal as this aligns with the dormant period before new growth begins. This timing reduces stress on the plant, allowing it to recover quickly and direct energy to new growth in the spring. Pruning after bloom can also encourage bushier growth and maintain an attractive shape without sacrificing next year's flowers, as bog laurel typically sets buds on old wood. Avoiding pruning in the fall is important, as new growth may not harden off in time for winter, leading to frost damage.
