Ornamental peach tree disease (fungus?)

We’re on westcoast of Australia. Mediterranean/sub-tropical climate…daytime temps currently 80-90deg.F, w/low humidity. We’re coastal/can get breezy. Recently purchased an 5-6ft. Double-flowering ornamental peach tree. After only a few weeks, the leaves are turning reddish-brown and falling off rapidly! I’ve bought Yates liquid copper fungicide, but not sure if I should use it on leaves at this time of year (mid-summer). Please let me know if you can offer any suggestions to treat this tree before it’s too late. Many thanks. Carol

If you are able, it would be a good idea to till some good composted organic matter, and dolomitic lime. This will act as a buffer for the soil, as well as add calcium and magnesium back to the soil. If it doesn’t affect the other trees, which are a prunus species as well, then that will work to your advantage. You could go with a completely unrelated fruit species, and more than likely be fine.
