My garden is nearly all grown from cuttings. I've never had any success with rooting powder/gel
& pots. Any time from spring thru to autumn I snap off a few twigs at a joint, I take some hardwood & some softwood of each type. Best done after a good downpour. Just push them in the soil & usually 1 or two out of three will root. Then can be transplanted to where you want it when established. Forsythia, Buddlia, Wiegela, Honeysuckle, Escallonia have all done brilliantly. I also pot up seedlings that have self seeded when weeding my gravel path and have Cotoneaster, Hawthorn, Beech, Roses, Ash, Horse Chestnut, Holly from this. Much more satisfying than doing it the 'proper' way! Good Luck!
