Wyevale growing media, garden nourish and control buyer Duncan McLean said: "Thanks to another unseasonably wet and mild winter with few hard frosts, our slugs simply haven’t hibernated as they usually do. They’re grazing constantly on prematurely budding plants, getting larger and larger in the process (up to 40 times their body weight), whilst also having the time to breed more, adding to existing colonies and spelling disaster for our gardens."
He added: "We are always looking for new, innovative and effective products. This year we have a new, first to market product exclusive to Wyevale Garden Centres, Sluggo Slug and Snail Killer Ultra, which is twice as potent as the current ferric phosphate pellet. It is biodegradable and will not harm children, pets or wildlife when used as directed, it contains ferric phosphate, an active ingredient occurring in nature which biodegrades into Iron and phosphate benefitting the soil. We also advise on other management methods including the re-siting of slugs in non residential areas at a distance from your garden."
Buglife chief executive Matt Shardlow said: "Due to climate shifts, warmer winters and wetter summers, we’re seeing slugs become active all year round, whereas key predators like amphibians will only lay their eggs once year slugs are not so restricted. Coupled with the fact that general slug varieties are also reaching full size earlier than ever, gardeners are simply not getting any respite and need innovative management solutions."
Wyevale recommends plants that slugs don't like:
- Bergenia (elephant’s ears)
- Aquilegia species
- Euphorbia species
- Geranium species
- Digitalis purpurea (foxglove)
- Alchmilla mollis (lady’s mantle)
- Astrantia major
- Dicentra spectabilis (bleeding heart)
