Water: Border forsythia thrives in well-drained soil and shows drought tolerance after establishment. It requires watering every two weeks and enters dormancy in cold months, reducing water needs while preparing for spring blooms.

Fertilize: Border forsythia thrives with balanced nutrition from a slow-release 10-10-10 fertilizer in early spring for robust growth. Feed biannually, reducing frequency as border forsythia matures. Follow product label dosages to prevent over-fertilization, monitor seasonal needs, and support healthy dormancy in winter.

Pruning: Border forsythia produces bright yellow flowers early in the season. Prune in late spring post-flowering by removing older stems to promote new growth and maintain shape. Avoid excessive pruning to prevent reduced blooms. Regular maintenance improves health and air circulation, reducing disease risk.

Propagation: Border forsythia features upright branches with bell-shaped flowers, thriving in early spring. To propagate, use greenwood cuttings in late spring or early summer, ensuring leaves remain. Dip in rooting hormone and root in moist, well-draining medium with indirect light, promoting growth before garden transplantation.
