Hi Im new to this site. I started growing veg last year in 4 raised beds and a greenhouse. I am getting the greenhouse ready( a bit late maybe) and have bought a sulphur candle as last year had a bit of powderey mildew in the greenhouse. Do I need to clear out tools and last years growbags before I use it? I was going to use the growbags around garden but would the sulphur harm anything? Thank you for any advice. Regards Annie.
