Last year I had re-landscaped my yard by putting down black weed barrier cloth and 6 inches of mulch hardwood and pine mixed. I have about 20 rose bushes throughout my yard of mulch. The roses were beautiful untill all the nut grass had come through the cloth and mulch. I understand that by pulling them out will leave more tuber offspring to grow back. I tried to spot kill patches of it but I killed off 8 rose bushes in the proccess. It is still dormant right now and don't want that headache again this year. PLEASE tell me what I can do to eliminate this pesty weed without destroying what I have left.

I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!

Nutgrass is indeed a terrible weed. One option for your situation is to use a wiper type applicator to apply glyphosate (Roundup is one brand) to the nutgrass plants as they emerge. This will need to be an ongoing battle but in time would be pretty successful if you stay diligent all through the growing season and not give it a chance to recover even for a brief time.

You might want to contact your County Extension Office for other suggestions and product options.

Thanks for the question. Please stop in again soon!
