Soil Type

Water: Coughbush flourishes in coastal, sandy soils with some salt exposure. Once established, it requires watering only biweekly and demonstrates remarkable drought tolerance. As an evergreen, coughbush retains foliage year-round, enhancing landscape greenery, while adeptly managing internal water reserves.

Fertilize: For coughbush, apply balanced nutrition fertilizer quarterly using a slow-release formula to support growth and resilience. Ensure proper dosage to prevent over-fertilization, which can harm coughbush and the environment. Water after application for nutrient absorption, promoting health and thriving conditions for coughbush.

Pruning: Prune coughbush in early spring to promote healthy growth and shape. Remove dead branches first, then shape lightly, avoiding heavy pruning during its late spring to summer flowering. Regular pruning enhances air circulation, minimizes disease risk, and supports a sturdier plant.

Propagation: Coughbush propagates successfully through cuttings, promoting swift root growth. Healthy cuttings need a moist, well-draining medium, with rooting hormone enhancing success. Post-rooting, transfer to individual pots and ensure consistent, gentle watering for strong root establishment until they are ready for outdoor conditions.
