My Helleborus plants have not grown in 3 years...
I bought about 10 Helleborus plants through the mail in a sale 3 years ago and they have not put out any new growth or any flowers...they seem to be in a state of suspended animation. :-) They are under a dogwood tree in my back yard. We are in a forested area so there's lots of shade, but they definitely get some direct sun some of the day.
What can I do to get them to grow? I've tried Easy Feed, regular 8-8-8, manure, even some lime thinking the soil was too acid (there's moss growing nearby).
Here's a picture:
Thanks in advance,
