The climbing hydrangea holds on to the ground with adhesive roots. The flower plates with the showy, white flowers appear from June to July. The plant prefers nutritious, humus-rich and moist soil. Older plants can grow up to ten meters high, while younger ones grow much more slowly and are even quite lazy.
Climbing hydrangeas do not need pruning
Education cut not necessary
A systematic training of the climbing hydrangea is not necessary. After planting, fix the long shoots to the wall so that they can anchor themselves. Young shoots on the ground often form immediately on the wall and usually overtake any existing ones in growth.
Growth of climbing hydrangea
The climbing hydrangea builds a strong, gnarled structure that does not age even after years. The flowers appear from easily recognizable, thick top buds of annual side shoots.
Adherent roots can detach
The adhesive roots of the climbing hydrangea are only viable for a few weeks and then lignify. Once loosened, older shoots can therefore only connect to the climbing aid through new growth. It is best to direct shoots that have come loose from the wall to lower-lying shoots that are clinging to the wall. Remember that the remains of dead adhesive roots remain on the ground. Remove last year's inflorescences up to the first side shoot.
Rejuvenate climbing hydrangeas
Only the side shoots protruding from the wall bear the flowers. After a few years they will get longer and longer, then redirect them to short shoots close to the wall. Climbing hydrangeas are always planted in the spring before they sprout - i. H. between mid-March and early April - rejuvenated. In doing so, you only remove the overly long side shoots on short pegs on the framework and leave its size as it is. Alternatively, you can also shorten the scaffolding drives by half to two thirds. This measure strongly stimulates growth, but the wall with the remains of the adhesive roots looks ugly at first.
tips and tricks
The adhesive shoots of the climbing hydrangeas can hardly anchor themselves on very smooth surfaces or on wall paints with anti-algae additive and fall off again and again.
