Anyone have any idea how I can stop grasshoppers eating a mandarin tree without spraying some strong chemical on it? It's only a little tree- a foot an a half high, but grey grasshoppers have all but reduced it's leaf volume by half and will be gone completely unless I find a way of stopping them.
To be honest I had no idea grasshoppers would eat citrus leaves in the first place Oh and they haven't touched the other three citrus- lime, orange and lemon.
