Icky things in the rhizomes
Hello all. I was doing some early-spring cleaning up/weeding in the beds yesterday and I found one old "mama" rhizome hollowed-out and full of icky grub-like things. I put some diatomatious (sp?) earth on it, then found another with the same problem. We're about 4-6 weeks out from bloom time here, and about three weeks to the offical last frost date. Should I dig up all the iris "babies" in this area and replant elsewhere, or leave them in place and transplant after bloom time? Also, what would be best to plant where the old ones were? Zinnias?
Thanks in advance.
