Forget 6 inch cuttings, for bigger shrubs use bigger cuttings. Giant cuttings of 18-36 inches may be worthwhile on the following:- Cistus, Euonymous, Hebe, Leycesteria, Weigelia, Pyracantha or Kerria japonica. I have a friend who excels with Roses taken this way.

Proceedure for Cuttings
- Water the host plant well the evening before taking cuttings.
- Take cutting early in the day, keep out of the sun and spray with water to minimise wilting.
- Select a shoot with plenty of new growth. Cut it off cleanly at the base where it comes from a branch or cut below a swelling leaf node instead.
- Remove any flowers, lower leaves and soft tips by pinching out
- If the cutting has a woody bark remove a sliver an inch long to aid rooting.
- Have available one litre pots full of a free draining mix of grit and multipurpose compost.
- Dip the end of the cutting in fresh hormone rooting compound, such as Murphy’s, plant and water in
- Place in a humid environment eg. a plastic bag over the pot supported by canes, so leaves don’t touch the sides, and tied with a rubber band.
- Keep in a shady spot removing dead leaves regularly.
- In about 5-6 weeks, when rooted, acclimatise to outside conditions and overwinter in a sheltered spot
- Plant out in March
Climber Cutting Tips
- For many climbers it is worth burying the tip as well as the heel in the compost making an arch.
- Clematis montana throws up more side shoots when treated this way.
- Lonicera honeysuckles react well to this arching technique and may root at both ends
- The best cuttings are taken from growth which is just hardeneing.
- Take extra cuttings in case of failures
- Many climbing roses will grow as climbers from the new root stock. Those that were grafted onto climbing stock may not have the same characteristics.
