3 Reasons why the trumpet flower does not bloom

The Content Of The Article:

Many hobby gardeners, who see a blooming trumpet flower (Campsis radicans) for the first time, think immediately: "I want them too!" For there is hardly a perennial climber that spreads so much tropical flair and yet is hardy in our latitudes. If you have the noble beauty then brought into the garden, the anticipation of the beautiful orange flowers gradually gives way to a certain disillusionment - the climbing plant grows magnificently, but does not bloom! Here we name the three most common reasons for the lack of flowers.

1. No pruning

If a trumpet flower is supposed to flower abundantly, it has to be cut every spring. All previous shoots are radically trimmed down to two to four eyes. Since the flowers only sit at the ends of the new branches, the climber should form as many strong Neutriebe - and this cutting technique doubles the number every year, if you do not dilute the plants from time to time. If you forego the pruning, the shoots from last year are relatively weak at the ends and the new flower florets are much more sparse.

2. Seedlings propagated plants

Trumpet flowers, which are offered inexpensively in hardware stores or on the Internet, have often been propagated by sowing, because this propagation method is the least expensive. As with seedling propagated wisteria leaves in these specimens, the flowering is often long in coming. As a rule, it is not as abundant as in the case of vegetative trumpet flowers, which are propagated by offshoots, cuttings or cultivars.

Trumpet flower 'Madame Rosy'

If you want to make sure that your Tompetenblume comes from vegetative propagation, you should buy a variety such as 'Madame Rosy'

If in doubt, rather buy a variety, because then you can be sure that this comes from vegetative propagation. Common garden forms are 'Flamenco', 'Mme Galen' and the yellow-flowered variety 'Flava'. Note, however, that you usually have to wait four to six years for these plants to flower first.

3. Wrong location

On cold, drafty and possibly late frosty sites, one will have little pleasure in the heat-loving trumpet flower. The heat-loving climbing shrub should get a full sun and sheltered location in the garden, ideally in front of a south-facing house wall, which stores the heat of the sun and in the evening ensures a favorable micro-climate. When the late frosts kill the new shoots, the growing season is often too short for the slightly cold-sensitive plant - the regrown shoots usually do not flower again.
