Mountain laurel can be propagated by taking cuttings from healthy branches and growing them in pots, or by planting seeds

Propagating by cuttings

Take cuttings: In late summer or fall, cut a 6-inch piece of new growth from a mature mountain laurel shrub. 

    Prepare the cutting: Remove the bottom two inches of leaves, and slice off two 1–1.5 inch slivers of bark on opposite sides of the bottom of the cutting. 

    Apply rooting hormone: Dip the bottom of the cutting in rooting hormone powder. 

    Plant the cutting: Put the cutting in a pot with potting mix, making sure the nicked part is buried. 

    Water and care: Keep the soil moist and the cutting in a warm, bright location with indirect light. 

    Wait for roots: It can take up to six months for roots to form. 

    Plant outdoors: When the roots are established, you can transplant the cutting to your garden. 

    Propagating by seeds

    Scarify the seeds: Use a file to gently rub the outer coat of the seed until the inner coat is visible. 

      Plant the seeds: Put the seeds about 1/4 inch deep in a sterile, well-draining seed starting mix. 

      Water and care: Keep the soil moist and the temperature between 65°F and 70°F. 

      Wait for germination: Once the seeds have swollen, they are ready to plant. 

      Mountain laurel is a slow-growing shrub that can take years to produce flowers.
