Q&As/Pruning and Tree Care/Peach trees
I would love to know how to prevent gum on ripening golden queen peaches. Can you help?
Unfortunately gum on peaches and nectarines is part of the natural growth in some varieties and in some growing years it is more evident than others.
Fortunately, it is not a sign of some dreaded disease, rather it simply impedes on the otherwise unblemished appearance of the peach.
Ensuring your trees are well fertilised, irrigated when required and mulched over the summer months, can in some instances reduce the amount of gum produced.
Each year after pruning it’s also a good idea to spray with a copper compound such as Copper Oxychloride. This adds a protective layer and works as a preventative for a variety of fungal diseases.
