Helleborus under pin oak
Hi. We've had a mild winter thus far in Indianapolis. I have approx. 6 hellebores(Lenten Rose varieties; planted year before last) under the pin oak in the front yard. I also have some ferns, hostas, and bluebells there. Everything is fairly spread out; nothing is crowded. Despite making sure the hellebores are watered in the summer, they haven't made any attempt to spread or flower. They're just hanging in there. Any thoughts on what I could do to help them? I've looked through the postings to the forum and it seems that they tolerate some acid, so I don't think it's the tree -- but please let me know if I am wrong about that. Thanks!
