Astute gardeners understand that slugs often seek shelter in their favorite hiding spots during the winter months. If the winter is mild, these pests can survive and return with a vengeance in the spring, wreaking havoc on your garden beds.
However, if the winter is frosty, slugs will typically burrow deep into the soil to escape the cold. To effectively control their population, it’s important to take action in the fall. One effective method is using superphosphate—a powder that causes burns on the bodies of slugs.
To apply, simply sprinkle the superphosphate over the mulch layer in your garden. You’ll only need about one matchbox worth of the powder per square meter of garden beds. This strategy will help reduce slug numbers and protect your plants come summer.
