Lestv Leslie, It is funny you should say that, I am currently trying something for the local AIS club. I have 20 Iris that I purchased and the i purchased the grow pots and am experimenting to see how much increase we can get for our fall rhizome sale. I think I should try this with a couple of dwarfs too. The colors seem to be much more vibrant, especially the reds.
Thank you so much for your response, Carla
