I want to take some cuttings from some wild red plum trees I found growing fairly close by and have me my own yummy plums growing close to hand. (Wanna try my hand at some homemade plum wine!) My query is how do I get the tree cuttings to root? And when should I take them? Before or after they fruit for the season? I have some rooting hormone powder for plant cuttings....will that work with tree cuttings?
