Q.My Large Hibiscus Is Still Blooming The First Week Of Oct. Here In Mokena, IL. When Should I Prune It To Move It To A New Locatio
My hibiscus has grown to large so quickly that it covers up one of my basement window covers. I have to move it this fall

Still blooming here in Texas too. I also have to move another hardy hibiscus as well but, I am waiting for the plant to go fully dormant (drops the leaves; browns out/dries out the stems). If you prune now, that may trigger new growth that will get killed by early frosts. So I prefer to move them when they are dormant later in the fall or in winter. But since you are in IL, make sure you do it before the soil freezes. Or move them after the soil has thawed in spring before they produce new growth.
