I have found a white chalky substance in my veg patch, and when I took it to a local garden centre they identified it as cat's poo. Its obviously old and I wondered how it will affect the plants. There is currently a victoria plum tee and some rhubarb in the plot as I have taken out everything else, neither of these is flourishing, but the rhubarb may need dividing, and I had a good crop from the plum tree last year although there don't seem many this - I think this is common for plum trees.
Does anyone know if there is a way to neutralise this stuff,so it not affect any future planting. It is unrealistic to remove it.
