Gardens are unnatural situations where many of us encourage plants that wouldn’t normally grow there, dig up those that want to grow there, make special efforts to encourage daffodils to flourish, mow the lawn to stop anything special growing too high and trim the hedgerows into unnatural straight lines. Slugs and snails positively thrive in these environments, particularly if we are growing salad plants and other tasty treats.
Slugs and snails are very important. They provide food for all sorts of mammals, bird, slow worms, earth worms, insects and they are part of the natural balance. Upset that balance by removing them and we can do a lot of harm.. Thrushes in particular thrive on them.
Sorry gardeners. Rewilding anyone? 😀
