how much blood meal is too much
I have some trouble with squirrels and/or chipmunks (I have both but don't know who's to blame) digging in my perennial beds. In some cases there are actual holes, so I tend to blame the chipmunks. If I put it down, they'll dig it up. Buggers.
Anyway, I found that sprinkling a bit of blood meal on top of the mulch (shredded cedar mulch) will keep them from rooting around in it.
But how much blood meal is too much? I am growing flowering perennials and cherry tomatoes in the areas in question.
