This is one of the better reasons for trimming back all your perennials in the fall. Less hidey-holes for the resident rodents. There are probably half a dozen of these holes in the Birthday Garden alone, and there are plenty in my other garden beds, too.
Where’s a feral cat when you need one? Or an owl?
When I feel like torturing myself I think of all the delicacies the voles are feasting on. Expensive corydalis. The lilies I grew from seed that my grandmother had given me.
There are two holes near the base of the rose bush I planted this spring. Do voles like rose roots? Probably, as with deer, they’ll eat almost anything if there’s enough competition. And there does seem to be an awful lot of circumstantial evidence that there are more voles than usual. And why not? All that rain we had made for lush growth and plentiful seeds to support a bigger-than-average vole population–and hide it. And when (or should I say if?) it snows, the snow will hide them, too. So it’s now or never: come owl, come cat–and feast!
