Old bearded iris bulbs
I found some old bearded iris bulbs in my moms attic. They have probably been up there 15 plus years. I have planted them with the roots down around a mound of soil and the tops barely covered with soil. The dried stalks are peeking up through the soil. When can I start to see growth and green in the stalks....if ever. Any tips for me to get these old irisis to grow and bloom?
