as varieties of the same species.
The most destructive member of the round backed tribe is the garden slug. Smaller and smoother than the large black, with a yellow or orange sole. No seedling or strawberry is safe from this blighter! And it likes a munch on the potato crop as well.
The last two species in the group Bourguinat’s, and the dusky slug feed on funghi and decaying material so we can leave them to do a good job for us.
With all this in mind, and as many Friends I know prefer to garden organically, I have started a list of things that I grow at Bryn Castell that don’t seem to be eaten by slugs and snails, and I would love to hear from anyone who can add to this. As you see there is no shortage of such plants available to us.

Finally, I pass on to you a slug control method dating back to fifteenth century France, when the Cardinal Bishop of Autun intervened for his slug ridden congregation, ordering public processions in every parish and enjoined upon the slugs to quit the territory in three days or be accursed. I didn’t hear how successful this proved but it might be worth a try.
