Q.Iris
I live in Iowa. The weather has been quite Spring like. Instead of yellowing and fading my Iris are putting out a lot of new leaves. They are getting quite tall. Should I be cutting them back to stop this?

Cutting them back won't stop the leafy growth. When other plants lose their leaves, cut them back to 3-6 inches so they look tidier over winter. Make sure to pick up any iris leaves that have dried and fallen on their own. I don't believe this surge of growth will harm the plant at all. That rhizome stores a lot of energy! I think your iris is simply saying "Whew, a break from the heat".
