Care Mountain Laurel ‘Keepsake’ Care Plant in Partial Shade to Full Shade. Morning sun with afternoon protection is ideal for best flowering and foliage quality. Provide moist, acidic, well-drained soil enriched with organic matter. Avoid alkaline or poorly drained soils. Water regularly during the first growing season to establish roots. Once established, provide supplemental watering during extended dry periods. Apply a balanced slow release fertilizer formulated for acid-loving plants in early spring. Mulch lightly around the root zone to retain moisture and regulate soil temperature, keeping mulch away from the stem base. Deadhead spent blooms after flowering to maintain a tidy appearance. Prune lightly if shaping is needed. Container Growing: Use a container with drainage holes and an acidic, well-drained potting mix. Container-grown plants require more frequent watering than those planted in the ground. Plants hardy in the ground may require winter protection when grown in containers in colder zones.
