solomon seal colony collapse
Has anyone had problems with sudden loss of solomon seal plants?
I had two large colonies of great solomon seal growing under trees in my yard in Rhode Island, they flourished for almost 20 years. Last year, the largest colony died out in mid-summer, virtually all at once. The plants did not return this spring. Now, a second colony about twenty feet away has also died. In fact, almost every solomon seal on my property is now gone.
I saw little evidence of insects - these plants were healthy for 15 to 20 years. Any ideas are appreciated. I grow mostly native plants and these were my favorite of all. Thanks for any help.
