I am about to move into a house with a garden that has been taken over by a large Rose of Sharon - it has sent shoots out all over the yard. How can I eliminate the shoots, while keeping the main plant?

In my experience it would be highly unusual to see a Rose of Sharon (Hibiscus syriacus) sending up shoots over a large area. Instead, I suspect you are seeing seedlings. This plant is known to self seed with abundance unless you are growing one of the more modern varieties, some of which are sterile or nearly so. To combat the seedlings each year, you mgiht want to deadhead or trim off the faded flowers in the fall before the seeds have time to mature. They are also relatively easy to pull while small. Larger offspring may need to be treated with an herbicide such as glyphosate formulated to control brush or woody plants to achive control. Be sure to read and follow the instructions carefully.
