I've already harvested my Solent Wight garlic because unfortunately they didn't escape rust. However, despite being harvested early(I planted mine in modules in a coldframe in January) the bulbs are huge, much bigger than previous years and are now hanging from the roof of my shed to dry. I usually transplant my winter leeks into the bed vacated by the garlic, but are they likely to get rust too? If so, is there anything organic I can do to prevent this?
