The location of the trumpet flower in the garden should be chosen carefully as it is a poisonous climbing plant. On the other hand, under suitable conditions, the otherwise not very demanding plant shows an almost uncontrollable ability to bloom.
When is the trumpet flower blooming time?
The flowering period of the trumpet flower extends from July to September, producing numerous characteristic trumpet flowers in sunny locations without waterlogging in the root area. Young plants usually bloom from the fourth year onwards.
The climbing trumpet loves the warmth
Young plants of the climbing trumpet flower (Campsis) should be protected with straw or brushwood in winter due to their sensitivity to frost, but later the plants can also tolerate winter temperatures down to around minus 15 degrees Celsius. A sunny location without waterlogging in the root area ensures numerous flowers in the characteristic trumpet shape between July and September: The following factors can be to blame if the trumpet flower does not bloom:
- Plant is too young (trumpet flowers only bloom from the 4th year)
- it was fertilized with nitrogen
- there is a lack of young shoots (if no pruning is done)
What you need to know about caring for the trumpet flower
Since the trumpet flower only blooms on the new shoots (from the same year), flower formation should be stimulated with pruning every year. This must take place in February; in the summer, apart from removing spent flowers, no pruning of the trumpet flower should be carried out.
Tip
With a climbing frame, the trumpet flower can reach impressive dimensions. Therefore, during the summer months, ensure there is sufficient water supply and possibly also shading of the plant's root area.
