Looking for info about Corn Gluten Meal and Trifuralin herbicides
I am fighting fox tail, sand bur, spurge, bermuda grass and crab grass in my garden beds. I am going to be away for 6 - 8 weeks next summer (monsoon season).
I have 2 kinds of pre-emergent herbicide that I would like to try on my garden beds. Neither one specifies that it is OK for use around bearded irises.
Anyone have experience with either of these kinds of (Pr__n) brand of herbicide?
