How to take semi-ripe cuttings
As the season progresses, the new shoots on shrubs start to become brown (woody) instead of green. At this point, they can be taken as semi-ripe cuttings. The extra strength means that the cuttings are less likely to wilt before they produce roots.

1
The ideal cutting from a plant, such as this rosemary, should be 8- 10cm long with 1-2cm of brown stem at the base. The shoot can be cut with clean, sharp secateurs or pulled from the stem with a ‘heel’ of bark attached.
2
Remove the leaves from the lower third of the cutting by pulling gently. If you have taken the cutting with a heel, trim it back to remove the thin tail.
3
Dip the end of the cutting in clean rooting hormone powder and tap off the excess. Never put used powder back into its container: just tip enough to use in one go into a saucer and then discard it.
4
Push the cuttings into a pot of multipurpose compost, water to settle and allow to drain. They will root outdoors or in a cool greenhouse. A cover will help protect them from excess rain as well as increasing humidity around the leaves to speed rooting. Check regularly for watering, as the compost needs to be moist.
