- I wouldn't recommend using alfalfa hay or regular hay for mulching if you want to avoid seed germination - as I'm sure you know hay is cut with the seeds on whereas straw is the by-product of removing the grain (seeds) from the cereal. So they will have many more seeds even if the hay is a couple of years old. If we do get any free or cheap old hay/alfalfa we use that as mulch/weed killer in our orchard, paddock (around trees) and tree nursery where germinating seeds aren't a problem as they eventually just add to the grass cover.
i can get bails of alfalfa hay that i would like to use to mulch my lettuce beds in a greenhouse this spring. any thoughts or other ideas?
