The new growth on my Portuguese Laurel have turned black. I planted the Portuguese Laurel as a hedge two years ago and this has happened each spring. I don't think it is being eaten by anything, I certainly can't see any bugs. Can anyone offer any advice?
I suspect that soft new growth has been frosted - although laurel is frost hardy, new growth is susceptible to low temperatures and drying winds.
It will grow new shoots, to replace the ones lost.
I'd give the hedge a dose of Fish, Blood & Bone (follow directions on the pack) this is a slow-acting fertiliser which will replenish the energy the plants will use to grow the additional shoots, without encouraging soft growth which will be vulnerable.
