Propagation – the breeding of specimens of a plant or animal by natural processes from the parent stock.

Intro

Before propagating, check that the plant you plan to propagate isn’t patented. A quick google search with the plant name should be able to determine if you’re allowed to. If it isn’t patented, then go right ahead. Propagation isn’t always successful but it’s really rewarding when it does. You can’t do this with all plants, but do some quick research.

How

Find your plant that you want to propagate, and cut off a freshly grown stem that is not blooming. If the stem is blooming, the cutting will put its energy into the flower and not put its energy into growing roots. Have your soil ready to go before you cut, and pot the cutting.

A cutting should be about 4 inches long, strip the cutting of most leaves except a clump at the top (the plant would put too much energy into the leaves and not root), and be cut in the morning.

Press the soil firmly down, and insert the cut side of the cutting into the soil. Use a spray to water the cutting well.

Cuttings need a warm and humid environment to grow, so putting a plastic bag over the top can often recreate these conditions well. The bag should not ever touch the stem or leaves. Place the pot somewhere like a greenhouse, bathroom, or kitchen. They should not be put in direct sunlight as it can often burn the shoot.

Rooting time varies, it can take anywhere from one week to a month. Wait until plants are big and healthy before transplanting, then transplant on a mild day and water (source).
