Care

Mountain Laurel 'Keepsake' Care

Plant in partial to full shade to avoid leaf scorch and encourage healthy blooms. Morning sun with afternoon shade is ideal for best flowering and leaf color.

Soil should be moist, acidic, well-draining, and enriched with organic matter. Avoid heavy or alkaline soils, which can impact growth and leaf color.

Water regularly during the first season to establish strong roots. After establishment, this shrub is moderately drought tolerant but still benefits from occasional deep watering in dry periods.

Apply a balanced, slow-release fertilizer designed for acid-loving plants in early spring. Our slow release fertilizer is a great option.

Mulch around the base of the plant to help retain soil moisture, regulate temperature, and reduce weed competition.

Deadhead spent flower clusters after blooming to maintain appearance and prevent seed formation. Prune lightly if needed to shape or remove any damaged growth.

Space plants 4 to 5 feet apart to allow for natural spreading and proper air circulation.
