Fertilizing ferns?

I put in a bed of Boston ferns a year ago that is finally filling in. I mixed bark chips into the soil (sand) and can really tell that I didn't mix too well, as some parts of the bed are nice and lush, and others are kinda skimpy. What fertilizer should I use on ferns to try to thicken the whole bed so I can stop weeding between the plants?
