[header] How to divide ferns [title] Water the fern generously two days before digging it up.

Add a couple of drops of ammonia or rubbing alcohol. (B) [step] Push the shovel straight down into the soil about 6 inches away from the fern stems, all the way around the fern. Then, push the shovel in again and lift the fern up out of the soil on the tip of the shovel. (C) [step] A plastic or a rubber shovel will work the best. Dig up as many ferns as you want. (D) [step] You can use a coarse hardwood spoon to do this. Only dig up the roots, not the leaves or stalks.
