Keep the fern in the same pots they come in, every other day submerge them in a 5 gallon bucket filled with 1/2 cup of epson salts & 3 gallons of regular water until the soil stops bubbling, then hang up to drip dry... ferns will be dark green, glossy, and 3x3 by September from ferns that start out with 7 fronds in May.
