Ideal Temperature

Water: Coastal plain willow thrives in moist habitats similar to wetlands and riverbanks, requiring consistently damp but not saturated soil. Water once every 2-3 weeks. Ideal for riparian plantings, it enhances soil stabilization and ecosystem health due to its high humidity tolerance.

Fertilize: For optimal growth, coastal plain willow requires balanced or high-nitrogen fertilizers during early spring and mid-fall, adjusting per guidelines and size. Over-fertilization risks harm, so thorough watering post-application is vital. Slow-release formulas support sustained growth, aligning nutrient needs with the plant's seasonal vigor.

Pruning: Adaptable to wet areas, coastal plain willow requires early spring pruning to remove dead or weak branches, promoting vigorous growth. Thinning crowded branches improves air circulation, reducing disease risks. Regular maintenance fosters a healthier structure and manages size effectively in garden spaces.

Propagation: Coastal plain willow propagates best through cuttings from healthy, mature stems measuring 10-15 cm (4-6 inches). Remove lower leaves, dip the cut end in rooting hormone, and plant in moist potting mix. Maintain consistent moisture and place in semi-shade to support root establishment.
