What is the best way to take and propagate rose cuttings??
10" semi hardwood cuttings in a trench with sharp sand at the bottom, in September. I am sure there is a very recent thread all about this -sorry I can't look for it now. Hopefully someone will find it for you, otherwise I will track it down later.
From last year's Gardeners World
....and it works! I watched Monty doing it. I thought he was doing it a bit early as September was warm and the cuttings were left uncovered. I thought they might dry out but most of mine struck and are well on their way right now. I'll have to give some away!
Unfortunately it never worked for me doing it that way as it was easy to forget them and allow them to dry out. My identical cuttings were planted in tall pots in a mixture of 50/50 GP compost and perlite, then kept in the greenhouse. I took cuttings in July, November and March, and have had a very high success rate with all of them.
