Climbing hydrangeas are best suited to disguise a shady north face, but also thrive in the full sun. After planting and in the following three to four years, a lot of moisture is needed, especially in summer. However, once the plant is established, it tolerates dryness quite well.

Select and prepare cuttings

Hydrangea anomala ssp. Petiolaris, as the climbing hydrangea in botanical Latin is called, can best be propagated via head cuttings. These are the shoot tips of an already woody, if possible this year's side shoot. This should have neither flowered nor have flower buds, both robs the Steckling simply too much strength. Choose a 10 to 15 centimeter long runner and cut it just below one eye. All lower leaves should be removed so that the cuttings do not evaporate too much moisture. However, the two to three uppermost leaves can stand still.

When are climbing hydrangeas best propagated?

The best time to grow climbing hydrangeas are the summer months of July and August. This hydrangea blooms between June and July, so the flowering is complete until the cuttings cut. In addition, the young shoots had enough time to mature.

Plant and care for the cuttings

The rooted cut surface of the cuttings should be kept as inclined as possible, since the shoot so the water absorption is facilitated. The immersion in a rooting powder also stimulates the formation of young roots. Then you can plant the cuttings of the climbing hydrangea in a sand-peat mixture, with a mixing ratio of 1: 1 has proven most useful. Place the pot with the young cuttings in a bright place away from direct sunlight and keep it evenly moist.

Young plants are still very sensitive to frost

The cuttings should not overwinter outdoors as they are still very fragile and freeze there. It is best to spend the winter in a frost-free but cool and bright place. The young plants do not reach their final location until spring, when no more late frosts are to be expected. This is to be expected from mid-May at the earliest. Fill the planting hole with a mixture of excavated soil, mature mixed compost and peat soil to give the young climbing hydrangea the best possible starting point.

Tips & Tricks

If cuttings are taken from leafy shoots, the moisture loss must be limited by the natural transpiration of the leaves: cuttings should be grown in a cold frame or under protective hoods (eg an inserted mason jar), where a high level of humidity can form.
