I have a small Echeveria that I bought a few months ago and I've been growing it outside. I live in the UK where rain, slugs, and snails are very common. It gets a lot of full sun during the summer outside and its leaves are constantly being eaten by slugs one by one and the rain is slightly overwatering it which is dangerous for a succulent.
I do have a window which faces directly at the sun where all my other plants get a lot of sun and they are also safe from the rain and slugs so should I keep my echeveria at that window or leave it outside?
I've tried putting rocks on soil and using pesticides but none of them keep the slugs away from it.
