IT'S NEVER ONLY A ROSE 2018

I agree with Verdun. With respects, to cut off a limb or similar and expect it to take root is like planting an established tree and then expect it to grow roots, rather like, puting the cart before the horse. Personally I have always prefered cutting like Verdun mentions and also more mature cuttings and pacing them in a slip trench. For the benefit of perhaps newer friends to gardening. A slip thrench is simply forcing the spade into the ground just easing back and forth, inserting the cuttings and treading the soil back. Hope this helps.
