You can take box cuttings in August to September, about 3 to 4 inch stems dipped in some rooting powder or gel if you have any, into gritty compost. by early the next year you should be able to pot them up singly. It takes about two years to get plants the size to plant out .( cut the stems just under a leaf and remove the bottom few leaves or take heel cuttings, I usually do a few of both and just keep them in a unheated greenhouse and most take)
