Lyn, I feel ya there speaking of living in an older body. When I was younger I was lazy about some tasks that my body could perform easily, now I don't mind the tasks and body does't cooperate, LOL.
For a few years I've had a great supply of free mulch that local roadside tree trimmers had dropped off, but that supply has all been used or completely decomposed (the composted piles are now a veggie garden), and I've been wondering what my next move should be. I certainly can't afford commercial mulch for my big beds, so I'm really happy to see this article! I've been using alfalfa pellets this year and feel like they've made a positive impact, so it stands to reason alfalfa mulch would be a really healthy mulch. I haven't priced it from the feed store yet, but this being horse country I think it should be plentiful and readily available.
Frank, thanks for sharing this great idea!
