Thanks Larry, I haven't tested the soil yet but will put that on the "to do" list. Soil is very loamy with a lot of organic matter, and I'm sure on the acidic side do to Leyland Cypress and Black Pines being there for years. Other daylilies around the yard planted after a major re-landscaping by the contractor a few years ago do very well, looking to give a little boost to both old and new
