Hi! I am in need of some advice for my neglected Lilly pilly hedge. It is currently very holely and thin on the bottom, with many gaps as in pictures provided. I have already taken off atleast 30cm on top, and on sides. However, I’m wondering if anyone would advise to take more off the top which would allow further new growth below? Another 1/3 off? It already has new growth coming through in lower half. Additionally, it has white wax scale and new growth being eaten by a green grub I have seen, most likely from the Lilly pilly beetle from what I’ve read. Is pest oil and eco-neem with a bit of eco-oil the best bet to rid of these nasties? Cheers!
