On Sunday I picked 22 slugs off my small hostas. ( Just to reassure readers, I don’t do this regularly – I do have other things to do!). With the advent of damper weather they are really starting to show themselves. For those who love growing hostas, slugs and snails are probably the biggest pests and even the giants like Sum and Substance and Big Daddy are not always immune to their predations. Growing in a coarse medium, or using environmentally friendly slug pellets, doesn’t necessarily solve the problem because slugs are smarter than you think. If necessary they will abseil down a neighbouring plant to get at the leaves of your hosta, so anything at ground level will not always stop them.
Preparatory products have been, rightly, removed from the market as they have proved toxic. A garlic wash has long been recommended as an alternative and I have used this myself in the past.
When I recently bought some new hostas (those of you who know my garden might wonder why I need any more, but I justified the purchase on the basis that one was a replacement for Dancing Mouse and the other was a gift) the recipe for a garlic wash was included with the plants, which I thought I would share with you. Please see below.
