Q. Who is Mr. Smarty Plants?

Title: Understory plants for Tuolumne Co., CA
Answered by: Nan Hampton


My driveway is lined with purple plum trees. I would like to grow something underneath them. What can I grow that will not harm the root system/health of the trees?


Mr. Smarty Plants isn't sure whether you want a groundcover, wildflowers or shrubs; but here are a variety of plants that are native to Tuolumne County California, should work well in your area and should not harm your plum trees. The only harm that could come to your plums by planting beneath them is the actual act of digging the holes which will disturb the roots. Try not to cut major roots (those thicker than your thumb) in the process of underplanting your trees.
