Ferns reproduce from spores, rather than seeds, and can be propagated in soil-if you don't mind a bit of a process. Luckily, ferns are much more easily propagated through cuttings! The best time to divide ferns is in the spring. Dig up and gently pull your fern from the soil. Then, pull or cut the plant into two or three clumps, using a garden fork or clean knife. Make sure that each clump has several roots, as well as a healthy growing tip. Then, reset the plants in soil, and keep them well-watered.
