Arlyn,
thanks for that reply. I seem to be the cheap gardener who wants to use as little as possible and still get good results. My budget can only afford a few plants, and the more I spend needlessly on things like bone meal, the more I can spend on plants. I see people recommending all sorts of things to build up their soil, but I often wonder just how much if any of it is really needed. I would especially like to here from growers who add very little if anything to their Iris beds and still have good results, or on the opposite side people who have tried adding very little and had bad results. Especially in the latter cases I would find it helpful to know what they added that did help noticeably.
