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?
