Well it's not hay but... It's actually my ornamental grasses. They are thick and I hope they are hurting my garlic. Like real thick, wheh do you normally remove a covering from garlic? If it's to early, we are definitely not out of winter here yet, I could go take off some of it. I'm worried the cover is choking it out. It is growing undrneath and it has the green to white look, like it's not getting enough light. I would hate to loose any.
