Can chillie, cayene pepper, curry powder, cumin etc damage the soil
I have a massive problem due to cats, I have tried lemon, garlic, mint, lavender, bottles with water in, spraying them with water and 2 sonic type things to no avail. They seem to think my garden is their private toilet. I have now taken an active dislike to cats when they never bothered me before. I was replacing all my spices so thought I would sprinkle all my old ones in the borders and it seems to have worked! So I have bought more to carry on doing this. Thing is I have to use quite a lot, plants seem ok at moment but can it do harm if I continue using it?
