I just bought 4 bags of Whitney Farm's "Uncle Malcolm's Weed Whoppin' Mulch"
which includes corn gluten as one of its ingredients.  My plan is to use
this mulch on a rose & perennial bed that we began planting last fall.
Currently, the bed contains roses and Blue and Rose Queen Salvia.  I am
about to plant clematis, hardy geraniums and some daffodils that didn't get
planted last fall as well as some pansies, for instant color, in the bed
before I mulch.

My question is: does corn gluten present a problem for perennials and bulbs
that died back to the ground in the winter?  In other words, will it
inhibit/kill the new growth next spring or restrict the spread of new growth
for the more mat like hardy geraniums?
