Answer: Ferns prefer a rich, humusy soil, and so would probably not thrive in your sandy soil. A few ground covers to try are: ajuga reptans (sun or partial shade), bearberry (sun), Cerastium tomentosum (also called snow-in-summer) (full-sun), bird's foot trefoil. You might also try daylilies, creeping juniper, or yarrow. You can also try to improve your soil by adding lime and lots of organic matter--compost, leaves, grass clippings, etc. You can either apply these as mulch or till in.
