Okay, my gorgeous rudbeckia plants begin to turn brown and eventually the whole plant dies, then another, then another. My spiderwort (tradescantia), an extremely hardy plant, begins to turn brown, then wilts right down.
Daffodils-have had some of them disappear.
I have tunnels in my sand (yes, my yard is mostly sand- all too easy for critters to dig in.)
Voles- what repels them? Will Allium? Garlic?
I love my brown-eyed susies, and spiderwort, too. Also, I have quite a few lilies and there are definitely fewer than I planted. While my cats catch one occasionally, they're definitely not doing the job. So, what have you found to work to deter or remove, voles?
