We planted our garlic in the fall and mulched it with certified weed free straw. Unfortunately our "straw" contained quite a few seeds and now we are growing a wheat crop around our garlic plants. We are having a fairly mild winter, temps haven't dropped below 20 degrees so the wheat grass is growing quickly. Should we weed and pull back the mulch now while the wheat grass is fairly short? Or wait until the spring and weed when temperatures are warm enough to pull the mulch off? Any input would be appreciated.
