have just planted my garlic. I lost most of mine this year because of rust. Does anyone know if enviromesh will stop rust?
simple answer is no, rust is a fungus and the spores are microscopic,
just keep your plants rotating around so you don't grow the same sort of stuff in the same place year after year, any material that had rust should also have been burned or binned, not put on the compost heap as you're spreading the spores around.
