Doris I put a good handful or two in the hole and mix in with the soil. Then I backfill the hole halfway and then add more alfalfa, I just pick up a handful and spread around. Once I fill in the hole I top dress with even more alfalfa, again a handful or so spread around. Also, there is alfalfa tilled into the bed before planting.
Let's say this is done in Sept or Oct, then I will top dress again in Jan or Feb and then again in Apr or May. Since the foliage is pretty grown up and it would take too long trying to get it around each daylily (the way I have them) I just pour it in a line in between the daylily rows; the roots are spread out so it doesn't have to be right around the daylily anyway. So basically I do it every 4 months.
I think I got the BAP from the same person as you and he didn't say not to put it in the fridge and others that I know use it keep it in the fridge so I just put mine in the fridge, when I order some more I will ask him about this.
