A flowering wisteria is a feast for the eyes. However, if the plant isn’t flowering, there could be various reasons for this.
Wisteria isn’t flowering: reasons
This impressive climbing plant delights amateur gardeners with its beautiful blue-violet flowers – but only if it is cared for properly and regularly. If wisteria is not flowering, it may be due to a lack of attention – or the wisteria may still be too young.
- Wisteria blooms after two to three years at the earliest. If you do not prune the plant, it will take even longer for the first flowers to appear.
- However, not all wisteria is the same; there are different varieties. They differ not only in growth rate and size. There are varieties that only bloom for the first time after 10 years.
- If you have grown the wisteria from seed yourself, it is possible that the plant will not flower at all. Even though growing your own is more fun, it is better to buy a young plant. However, make sure that it is grafted.
How to get wisteria to bloom – here’s what helps
The necessary measures to get wisteria to bloom must be taken early on. If you want to plant wisteria, you should choose a suitable location from the outset.
- The plant likes plenty of sun. However, house walls or even rain pipes are not suitable supports. Loose masonry, wood paneling, roof tiles, and downspouts will not withstand the strong branches of the plant for long and will certainly be damaged.
- You should also allow for sufficient space. Wisteria is a climbing plant and can grow up to 10 meters long.
- Wisteria also has specific soil requirements: the soil should be rich in nutrients and low in lime.
- Wisteria must be pruned in order to bloom beautifully and profusely – even when it is still a young plant. Pruning is quite radical: cut back everything except for a few buds.
- The climbing plant only blooms on short shoots. Therefore, the long whip shoots must be cut back consistently. Ideally, leave two buds, no more.
