Hello Rick,
I am sure they do! I was just saying they do not test them. I have a lot of varieties that do not do well in this heat so I just order the small ones or purchase them at a cheap price from coops, I actually have quite a few. I bought Paul's Glory at a local nursery and it just bit the dust, it got smaller and smaller because it requires a good cold spell and it was not getting it here. It sure was spectacular when I bought it though! I have always used milorganite, the hostas love it and the cats and squirrels hate the smell. I found that my daylilies love it too and it is cheap too. Alfalfa is fine if it is the non-GMO, but I live in a city and had to drive 25 miles to get it one time and to me the milorganite was just as good.
