Pittosporum Eugeniodes hedge is thinning a lot

Question

My Pittosporum Eugeniodes hedge used to be very thick and lush but has recently started to loose leaves and appear thin. It used to block out the neighbours but now we can see straight through. The leaves are not yellowing or don’t look sick but the shrub just looks like its thinning a lot. What is the likely cause? I live in Melbourne

It will be hard to know without photos of the hedge, and closeups as well. Sometimes, they just need a hard pruning to bring it back. You may need to fertilize, but this is rare.

Usually, regenerative pruning will be your best option. This article will help: https://www.gardeningknowhow.com/ornamental/shrubs/pittosporum/growing-japanese-pittosporum.htm
