How do you root a cutting from a tree?

Cuttings of some plants need to be taken by cutting at a specific place and at a certain angle.

Otherwise any clean, angled cut through a green branch should be sufficient.

The cut part should be dipped into a rooting powder - to promote the growth of roots - and the cutting should be inserted into moist potting compost. and watered slightly.

The pot may need to be covered with a polythene bag to protect the cutting from infection and from insects, and to retain moisture and encourage growth.

If you are interested in a specific type of tree, then check out the internet for detailed instructions.
