Well, by far, the easiest way to guarantee a cutting is by taking new wood. This will mean that it will take a little longer to mature, but you can get much better success rates with new wood. This article will give you more information on taking cuttings from shrubs and trees: https://www.gardeningknowhow.com/ornamental/trees/tgen/how-to-root-cuttings-from-various-shrubs-bushes-and-trees.htm

Q. Stopping fruit/nut production

We have two mature macadamia nut trees in our (Southern California) garden. They produce
prolifically, but despite trying MANY techniques over many years, we are unable to successfully harvest and preserve the nuts. For us they are simply an attractive nuisance for rats. We want to stop the nut production. I think there are sprays for olive trees to prevent fruit from setting. Is there any similar way to halt the nut production on our trees without harming the tree?

Q. macadamia trees

I have 12 macadamia trees, however the monkeys ensure that I never get any nuts, I chase them, but they`re too sly.Anyway I have this idea to make shadecloth jackets for the trees.So I was going to wait for the nuts to get to about peanut size, and then pull my jackets over the trees, do you think it`ll be successful, or do you have any other ways of dealing with the monkeys?I live 35Km`s South of Durban, South Africa.
PS. Do you know what we call shadecloth, it is a plastic type of sacking.

I would not know how to protect against monkeys, as we do not have this issue in our country. Being as intelligent as they are I would say that just about anything you do will be outsmarted by their need for food.

I could suggest asking a local nursery about what they do when this issue arrives. Sorry I could not be of much help here.

Q. Macadamia tree

We live in Toowoomba Queensland. Our macadamia tree is around 20 years old but has not produced nuts for the last 5 years or so. We live on acreage and unfortunately have not looked after the tree in recent years, however we have more time on our hands now. Can you please tell me what I need to do to get the tree to produce again?

It could be that it is lacking fertilizer, or has contracted a disease. Can you include a photo? This article will give you information on their care in the meantime: https://www.gardeningknowhow.com/edible/nut-trees/macadamia/how-to-grow-macadamia-trees.htm

Macadamias can self-pollinate to some extent with one tree, but cross-pollination greatly increases nut production, so it's best to have two trees. Bees are the usual pollinators, and it they are unavailable you will need to pollinate by hand. Here is some information about which varieties seem to self-pollinate better than others:
