Slugs and snails are a hosta lovers worst nightmare. There is nothing worst than going out to the garden in the morning to find ugly holes in your prized hostas and the shiny track marks of the slimy culprits.
There are many ways of controlling a slug problem in your garden without resorting to slug pellets. Firstly consider the position of your plants, are they in a pot or a bed? Hostas in pots are much easier to defend against slugs and snails then ones grown in the ground. By growing in a pot you are able to restrict slugs and snails access to the plant without killing them. Copper bands are extremely effective in many cases, the copper band need to be wrapped around the pot to create a barrier the slugs will not cross. We have also found the using copper pots to plants your hostas in is a sure fire way of keeping out the slugs, be sure to line your pot with plastic before planting.
Organic Slug Repellent
It can be difficult to handle a slug problem when so many methods work for some people and not others.

We believe the best approach to take is to try a range of things and find what's right for you and your garden.

Are there slug proof hosta?
In short...no. All hostas can be targeted by slugs no matter the variety. What we can say is that there are varieties that are known to be slug resistant and not eaten as much but this obviously varies depending on how badly you get slugs in your garden. Generally the slugs will go for the fleshier leaves and will avoid thick tough leaves. If we put a 'Bob Olson' next to a 'Blue Mouse Ears' for example without any slug protection the 'Bob Olson' will more than likely be one one the slugs would go for as the leaves are fleshier and easier to eat than the thick leaves of 'Blue Mouse Ears'.
