My Oriental lilies (and peonies) are in the soil, which is fairly organic.........I was wanting to know about what NPK ratio is best for them. I've always used Miracle Gro (hose end sprayer) for them and they do ok; but if that doesn't meet optimum nutrients, then I want to give them the right thing. I'm thinking the peonies especially might do better with something else. The internet info is kind of inconsistent, so I thought someone here could help. Thanks much for the mulch/compost approach. If I can give them a shot of M.G. once in a while and not defeat my purpose, then great.
