How do you encourage ferns to spread?

The quickest way to grow more ferns is through division, preferably in spring. Start by watering your plant the day before you begin. Then, dig it up or gently remove it from its container, and cut or pull the plant into 2 or 3 clumps. Leave at least one growing tip—the spot from which the fronds grow—in each clump.

Do ferns come back every year?

Ferns plants in the ground can be left as is the entire winter. The fronds will protect the plant's center crown, where new growth will emerge in the spring.

Do ferns spread in ground?

Like other perennial plants, you can divide ferns in spring or fall. Keep the new divisions well-watered until plants are established. Some ferns spread by underground runners, which can be helpful in places where you want a groundcover, but unwelcome in an orderly, formal planting.

How do you stop ferns from spreading?

Ferns can be dealt with by repeated mowing or cultivating, by burning, and by salting them to make your cattle devour them. File that away. Whichever method you use, it is best to do it before the ferns let fall their spores.

Is there a fern that doesn't spread?

For modest gardens looking for a fern that won't take over the whole garden, turn to Polystichum aculeatum, hard shield fern—which doesn't spread and so remains quite compact.
