If a clematis is full of juice in summer, it offers plenty of plant material for vital offshoots. For varietal propagation, hobby gardeners favor this method, as it offers the best chances of success. The following instructions explain practically how to do it right.
This preparation creates ideal starting conditions for offshoots
Choose a shoot from the middle of a clematis for the scion. Make the uppercut just above a knot and the lower cut below a leaf base. A perfect cutting is 12-15 centimeters (4-6 inches) long. Except for one leaf, each offshoot is then defoliated.
Dip the lower interface in a rooting powder such as Algan or Wurzelfix and put the offshoots aside to prepare the seed pots like this:
- Carefully disinfect small pots with a diameter of at least 15 centimeters (6 inches)
- Place a small shard of pottery over the water drain
- Fill each pot three quarters with nutrient-poor potting soil
Finally, moisten the substrate well with water without completely wetting it. 4 wooden sticks or straws are inserted into the corners of the culture vessel to keep the cover that follows later at a distance from the offshoot.
Plant and care for offshoots properly
Plant the prepared offshoots of the clematis so deep that the leaf and substrate do not touch. Since the cuttings of a clematis root much more diligently in a humid and warm microclimate, put a transparent plastic film over the wooden sticks. This care promotes further growth:
- Place the growing pots in a semi-shady to a shady location
- Ideally, temperatures of 15 to 21 degrees Celsius (59-69 F) prevail here
- Keep the substrate constantly moist without causing waterlogging
- Turn the cover inside out daily to drain moisture
Within 6 to 8 weeks, an independent root system develops on each offshoot of the clematis. If the first tender strands grow out of the opening in the ground while fresh shoots are thriving at the same time, the process is proceeding as desired. As soon as a pot is fully rooted, plant the young clematis in its final location.
Instead of buying rooting agents, knowledgeable hobby gardeners simply make it themselves. Annual willow rods contain an abundance of natural growth hormones as well as salicylic acid to fight off infection.
Cut the rods into pieces, pour boiling water over them and leave to stand for 24 hours. Then strain the broth – done.
