Steve from Swartz Creek wanted to get rid of Marmorated Stink Bugs in the home. Use a vacuum cleaner or a light trap.
Steve also wanted information on stopping suckers (shoots) on the bottom of trees. You can physically remover them (best done when they’re very small) or use a material containing Ethyl 1-naphthaleneacetate. There are two products labeled in Michigan Tre-Hold made by AMVAC Chemical Corporation and Sucker Stopper RTU produced by Monterey Lawn and Garden. Follow the instructions so the material will be effective without harming the tree.

Bethany from Mount Clemens wanted to find a new home for her heirloom peonies while Ralph in Grass Lake wondered how to prevent the flowers from bending over after a rain. We talked about putting a cage around them, I tie them up using twine around the entire clump or putting a piece of 4 x 4 netting over the shoots just as they emerge and then raising the netting as the plant elongates. I forgot to mention that stems may be weak if the clump is too crowded so dividing the plant will increase stem strength. Here’s more information on peonies. A very large peony collection is located in UM’s Nicols Arboretum.
