re: Planted summer plots today

Crimping breaks the foilage which stops the biological flow in the plant. Herbicide would then not be absorbed into the plant and down to the roots.

You definitely spray the herbicide them crimp. Honestly, a good crimper removes the need for herbicide.

I’m a landscape contractor, so the one thing I understand is that a good mulch layer helps to retain moisture. A crimper breaks the growth and lays it down to protect the soil. When the mulch decomposes and restores the nutrients to the soil, it gets richer and microbes improve!
