The fertilizer, this type of plant food, provides nutrients that are necessary for the growth and health of weeping forsythia. The root system of this plant is important in anchoring the plant in the soil and absorbing water and minerals from the soil.
Pruning is an important part of keeping your weeping forsythia healthy and looking its best. Prune in early spring, before new growth begins. Cut back all of the previous year's growth to about 6 inches (15 cm) from the ground. This will encourage new growth and prevent the plant from getting too leggy.
Propagation is typically done through rooting stem cuttings taken from new growth in late spring or early summer. Cuttings should be 4-6 inches long and taken from the tips of the shoots. Remove the bottom leaves and dip the cuttings in rooting hormone before planting in a well-drained potting mix. Keep the soil moist and provide bottom heat until roots form and new growth appears. At that point, you can transplant the rooted cuttings to their permanent home.
Usually, the plant growth rate is between 6 and 12 inches per year. They can however, grow up to 24 inches in a year if they are given the right conditions. The weeping forsythia requires full sun to partial shade and moist, well-drained soil.
