We're pretty flexible, so we could use it for mulch or compost. As the 'blight' does it heaviest growing in the summer, it makes most sense to use it as a mulch. But we also use other items, like pre-existing compost and/or coffee bean bags, as mulch as well. The more material, the better! What's nice about the grass clippings in particular is that they are high in nitrogen, and generate a good bit of mycellium (fungus), which in turn gives vegetative plants greater access to nutrients!
