Fertilising a Wisteria sinensis
For the vigorous and enchanting blooms of Wisteria sinensis, it's essential to provide adequate nutrients through fertilization. Commence fertilizing early in the spring, as growth emerges, and again in mid-summer to support the plant's energy needs during its flowering phase. A balanced, granular fertilizer rich in phosphorus can promote robust blooms; apply according to the manufacturer's guidelines, ensuring even distribution around the base of the plant.
In regions with fertile soil, it may only be necessary to fertilize once annually. However, in poorer soils, more frequent feeding may be required. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers. Regular watering after applying fertilizer will help dissolve nutrients, allowing them to be absorbed by the plant's root system more effectively.
