Q.How can I tell if my iris rhizomes are still fertile
How can I tell if my iris rhizomes are still fertile after storing in my basement over the winter? A friend gave me some iris late last fall and I forgot to plant them. So I kept them in the basement and dry. Is there a way to tell or test if they will grow?
One way to tell if your rhizomes might still viable is to give them the squeeze test. If they are firm, there's a good chance they are, but no guarantee. Plant them in well-draining soil, water generously and cross your fingers. Hopefully you'll see sprouts within a few weeks. Good luck.
