My hosta, which is in a pot, has just started to poke through the soil. All the leaves are still curled up tightly and it has the potential to look beautiful. HOWEVER, I know as soon as they start to uncurl, the damn slugs will arrive in droves! What can I do now, whilst there's still plenty of room around it, to stop the little blighters coming for an 'all you can eat for free buffet'?
