The Weigela impresses the viewer not least with its lush abundance of flowers. If this doesn't happen, then it's more than a shame. Find the cause so that you can enjoy the usual splendor of colors again next year.
Why is my weigela not blooming and what can I do about it?
If the weigela doesn't bloom, it could be due to too little sun, incorrect pruning or aging. To get them to bloom again, a change of location, a rejuvenation cut or a pruning directly after flowering can help.
Why doesn't the weigela bloom?
Even if the weigela can generally be described as easy to care for, there are still a few reasons why it doesn't produce its usual blooms. These are usually due to the location or care, but diseases are rare in weigela.
In addition to a lack of light, incorrect pruning is a common cause of sparse or no flowers. If you cut the weigela back in the fall, there is a high risk of accidentally cutting off the flower buds for the coming year. These form before winter and not on the young spring shoots in the year of flowering.
But not only too much cutting damages the abundance of flowers on your weigela, but also too little. If it is not pruned at all for several years, it tends to age. The old shoots become increasingly woody and produce no flowers and only a few fresh shoots.
Possible reasons for failure to bloom:
- too little sun
- wrong pruning
- Aging
How do I get my weigela to bloom lushly again?
If too little sun is the reason for the lack of flowering, then you have little choice but to transplant the weigela. You should do this in good time, because if the plant is older than about four years, it won't do well with a change of location.
You can get an old weigela back on track with a radical rejuvenation cut. To do this, shorten all shoots to a length of around 20 centimeters. The spring after next it will be in full bloom again.
Tip
It's best to always cut back your weigela immediately after flowering. This means there is neither the risk of aging nor of cutting the wrong shoots.
