Answer: You're right, spurge is an annual that dies at hard frost, but it spread a LOT of weeds before it gets buried in snow. Spurge grows especially well in midsummer, when your grass is stressed by heat and dry weather, and can't compete. I suggest that you use a corn gluten based herbicide called WithOut Weeds, sold by Gardens Alive (ph# 812/537-8650, or write to 5100 Scheneley Place, Lawrenceville, IN 47025). Corn gluten produces some kind of enzyme that kills sprouting seeds. It also contains 10% nitrogen, so it feeds your lawn, too. I hope this does the trick for you!
