Cuttings are great! Basically you can create infinite plants from just one plant, with a little time and some know how.
When you take a cutting there are a few things to know. You are creating a genetic clone of the plant the cutting is from, this is how apple trees have fruit that tastes the same.
There are many types of cutting that can be done, succulents can be grown from only one leaf. Soft wood cuttings, like tomato plant, grow when plopped in fresh water and then into soil once they have established their roots. Most of the cuttings I do are hardwood cuttings, they’re a bit more tricky.
