OAK LEAF HYDRANGEAS - it’s getting close to the ideal time to trim & tidy your oak leaf hydrangeas. Depending on where you live in Australia & what position your hydrangeas are in this can vary plant to plant. I find as a general rule pruning these is best done late summer into autumn (may be later in cooler regions, like I said it depends on on your individual plants) Unlike other types of hydrangeas, oak leaf, prefer a more gentle trim removing only 1/3 - 1/4 or even just a simple deadheading
