Q: I’ve read about planting moss lawns, but can’t find anyone in Atlanta that knows about it. I have a very large tree in my front yard that doesn’t allow for grass growing.

A: Having a moss lawn is tempting when your grass dies due to shade but its care is almost as exacting as a lawn. Remember that moss loves excess moisture, clay soil and shade: the same three things grass abhors. That’s why grass won’t grow under your tree. Your two biggest chores will be providing constant moisture in summer and being persistent about weed control. If you can provide the right conditions, your mossy area can be very attractive.
