Growth Rate

With rapid growth in spring and summer, roughleaf dogwood swiftly increases in height and expands foliage coverage. During these active seasons, the accelerated growth rate expresses as a profusion of leaves and flowers, accompanied by a notable vertical reach. Nonetheless, the intensity of the growth speed slightly moderates during mid-summer, giving this plant a unique dual-phase development. This dynamic growth adaptation makes roughleaf dogwood a particularly interesting study in plant morphology and seasonally-adjusted development patterns.

Water: Roughleaf dogwood thrives in its native habitat, showing moderate drought tolerance and a preference for consistent moisture. Water roughleaf dogwood every 1-2 weeks, especially during peak growth seasons, to support lush foliage and flowering. Typically grown outdoors, its size and deciduous nature influence watering needs.

Fertilize: Roughleaf dogwood benefits from balanced or high nitrogen fertilizers during active growth in spring and summer. Fertilize biannually, adjusting application rates for growth phases. Use gloves, avoid foliage contact, and water after applying. Adjust fertilization seasonally, with lighter applications in fall and pausing in winter.

Pruning: Roughleaf dogwood features rough leaves and white flower clusters. Early spring pruning removes dead branches, encourages growth, and prevents disease. Use clean, sharp tools for precise cuts above leaf nodes. Regular pruning supports air circulation and robust flowering, ensuring quick healing and vibrant new growth.

Propagation: Roughleaf dogwood, a deciduous shrub from North America, is resilient and thrives in various conditions, particularly moist, well-drained soils. Effective propagation involves softwood cuttings from healthy stems, treated with rooting hormone. Maintain moisture and indirect light until roots establish for successful transplantation.
