Welcome to the Bunnings Workshop community. We trust you'll receive loads of helpful information, advice and inspiration for all your projects around the house and garden from our amazing members. It's great you could join us.
I can tag members to provide assistance with your struggling tree, but firstly can you please provide more information so our members can provide more specific advice? It would be helpful to know where you are based as well as when the tree was planted, what your soil is like, what care you have given the tree recently apart from watering, and when you first noticed a problem.
