The climbing trumpet flower (Campsis) is a relatively easy-care climbing plant that, in a suitable location, can provide greenery for privacy walls and house walls within a few years. It's annoying when the plant suddenly hardly produces any flowers anymore for no apparent reason.
Why isn't my trumpet flower blooming?
If the trumpet flower does not bloom, this may be due to the young plant age, incorrect fertilizer, unfavorable site conditions or a lack of pruning. Optimal care and regular cutting promote flower formation in older plants.
Be patient when caring for the trumpet flower
If your trumpet flower in the garden hasn't bloomed at all yet, this may simply be due to the age of the plant. With the various Campsis cultivars, it is completely normal that they only produce flowers for the first time when they are around 4 years old. In order for flowers to form as quickly as possible, growth should be promoted by optimal site conditions:
- sunny and warm
- sheltered from the wind
- Trail available
- sufficient moisture (water regularly in summer if necessary)
- nutrient-rich soil
Once the plant finally gets going, it will produce more and more flowers every year with appropriate care.
Care errors can be responsible for a lack of flowers
If older specimens of the climbing trumpet suddenly stop blooming for seemingly no reason, this can also be due to care errors. A common mistake with the trumpet flower is when it is supplied with nitrogen-rich fertilizer. The nitrogen contained in the fertilizer usually leads to very vigorous growth of the climbing tendrils in the climbing trumpet. In return, the plant then almost completely stops producing flowers. Therefore, make sure to only use fertilizer without added nitrogen (€12.00 on Amazon) to supply the climbing trumpet with nutrients.
Stimulating the flowering of the trumpet flower
The trumpet flower is not very demanding as a climbing plant, but lovers of lush flowering must expect a certain amount of care for this plant. The fact is that the climbing trumpet only produces flowers on the young shoots from the same year. Therefore, to ensure strong flowering, the climbing trumpet must be pruned annually. This is the only way to stimulate the formation of many new shoots and thus a magnificent flower.
Tip
The climbing trumpet can reach impressive heights over the years and literally overgrow garden sheds and trellises. When making pruning, be careful not to put yourself in unnecessary danger. If possible, ask a second person to secure the ladder when pruning the plants.
