1Q: I sent pictures of a weed that I have been battling for the past few years in my garden. I use paper and mulch or straw to help manage the weeds in my garden, but this weed grows anywhere that is not covered.

Addressed by Kelly McGowan, horticulture teacher, MU Extension

A: This is a weed called Red-Root pigweed. Red-root pigweed is a significant weed problem in much of the local area, especially in agricultural production because of its resistance to glyphosate.
