I had a new septic drain field installed. It is above ground and covered with

What would be a suitable ground cover for this sandy area, something that my
yard guy could plant?

When people install gardens on flat roofs here in the northeast -- mostly
to insulate -- the plants they like to use are the sedums. They don't need
watering. While I think of Florida as getting ample rain, the sand will
drain any rain out promptly. Some of the sedums are low and creep like a
ground cover.

They also use grasses here. Grasses can also take a drought. Certainly
beach grass likes growing in sand.

More suggestions can be found by searching on gardening in sand. But I vote
for a sedum, or a variety of sedums.

Sedums also flower profusely. Many people where I live plant sedums
on steep rocky slopes and around granite outcroppings that can't be
mowed... sedums require no maintenence... once sedum is established
weeds are smothered.
