Janice, that looks like a really fun garden to visit. No way does that lady look 90. See what gardening does for us.
I did a mini experiment this year with my lilies. I put daffodils along the lily rows. I read to put them about a foot apart, and something in the daffs repels the voles. i don't have a huge vole problem, but I have some vole damage yearly. This year I had some in other areas, and so far none where the daffs are planted.
