How to divide crowded Gerbera Daisy
 

We have a pot bound Gerbera daisy. It seemed to have 3 separate
crowns over the summer. Now, there are at least 6 distinct crowns,
and the root area is a solid tangle of roots. I could just slice thru
the crowns and roots to divide the plant, or hopefully learn somthing
here as a better way to divide the plant up. We liv in the Chicago
area and will use growing lights over the winter to keep the plants
healthy.

Help!!!
