The most likely reason your wisteria won't bloom is due to too much nitrogen. When a wisteria plant has too much nitrogen, it will have plenty of foliage growth, but very little and maybe no blooms. The last, and least likely, reason a wisteria won't bloom is over pruning. Over pruning will remove the flower buds.

Can wisteria be pruned hard?

Pruning Mature Wisteria Plants Cut back new growth and main branches to just two or three buds to keep the plant neat, tidy and ready for the forthcoming growing period. Hard pruning may be required if there are dead stems to deal with, or particularly woody areas of the vine causing gaps in the foliage and flowering.

How fast does wisteria grow in a year?

Wisterias are slow to mature and may not begin flowering until three to five years after planting. Wisterias are rapid growers and can shoot up 10 feet or more in a single growing season. That's great if you want to quickly cover a fence or pergola, but you don't want the vines to overrun your garden.

Can wisteria be cut back hard?

Hard pruning should be done in winter while the plant is dormant. Using loppers or a pruning saw, cut back old branches to just above a strong young shoot, or remove them completely if necessary. Hard pruning will encourage your wisteria to produce lots of new shoots in spring.
