So, this is my first attempt at propagating Holly, which is a relatively expensive tree for us to buy. Collected cuttings of new growth in mid-September. Cut the cuttings quarter inch below a leaf. Trimmed off all but two or three leaves. Wet the base and dipped it in organic rooting compound. Placed the cutting in a root trainer cell, having first poked a hole with a pencil in the general purpose compost. They will be kept outside on my mum's allotment. 2 hours work, but if they grow it saves us £30. Coming soon... Hawthorn!
