Grass in the last batch of Hay I just laid!! Can't tell what kind it is, but I will probably be covered with landscape fabric through the winter or with more mulch....thick layers of leaves, paper, etc to become part of the mulch/soil in the spring. Am I on the right track or do I need to suffocate it...seems like it would be added nutrients. Any other suggestions? Do not know what kind of grass seeds they are.
