In planting my last few roses last week
I lined the holes with Permatil AND poured about
a two-inch layer on top of the rich black soil which
forms the middle layer. My plan is to add organics
that will sift through the scratchy Permatil and feed
the roses next spring, and to add a fresh layer of
rich soil on top of the whole thing in the early spring.

This way the voles cannot outsmart me and go in to
get the roots from the TOP. Either that, or I will be
breeding a new, really tough-footed, Permatil
resistent vole. News at 11!
