Dividing Foxtail Ferns: Those "Potatoes" Are Storage Roots

Foxtail fern (Protoasparagus densiflorus 'Meyersii') is an inedible asparagus. The swollen "potatoes" store water and starch. To divide, use an old serrated steak knife to slice between clumps of tubers that have foliage stems attached. Pot up immediately, fertilize lightly, and give bright light. The divisions will match the mother plant's size quickly.
