The problem I have with Alfalfa...there seems to be no limit to how much you can use. That may sound strange, but I have yet to see any recommended rate of application. Every time I read an article they say put it in the hole, put in around the plant, top dress with it and broadcast it in your beds.
I read how Tink uses it also and that was the same conclusion I came to. So I have found that if I have a bag sitting around I tend to just use it till its gone.
I now look at it more as worm food and soil conditioner than fertilizer, I love the stuff, but it can delete your daylily buying budget pretty quickly if you're not careful.
