After 55+ years of gardening, I've worked up the nerve to try my hand at Lady slippers, I have a small collection of Showy and Yellow Lady Slippers. They are in a North facing raised beds, that has been filled with grass and leaves over several years. They get dappled sun and moisture from an irrigation system. Any and all suggestions would be appreciated how to maintain and get them to thrive. I was lucky to get my yellow to bloom a few weeks after transplanting. Thanks again.
