You too can grow fabulous ferns

Perfect for highlighting a shady spot in the yard, ferns are a welcome addition alongside a pond or in a rock garden. Here are a few care tips, as well as a list of different ferns you can add to your garden.

You too can grow fabulous ferns

Ferns may require supplemental water in dry weather, but once established, they often prosper for years with little care.

A preference for shade

  • Most hardy ferns prefer dappled rather than deep shade.

The amount of sun a fern tolerates depends on the moisture content of the soil — the wetter the soil, the more sun the plant can handle.

Multiply ferns

Ferns develop dust-like spores rather than seeds. Unlike seeds, spores have no food reserves and they need a wet environment in which to grow.

  • Instead of trying to grow new plants from spores, divide ferns to increase your supply of plants.
  • The best time to dig them is early spring, when the new fronds unfurl.
  • You can dig and successfully move wild ferns pretty easily, provided you have written permission from the property owner.

Feed ferns last year’s leaves

  • Before you create a new leaf pile in the fall, turn and mix what's left from last year and spread the crumpled, half-rotted leaves over your fern bed.

This mimics the natural habitat of most hardy ferns, which grow in the cushy leaf mulch that covers the forest floor.

Wait until spring to clean up old fronds

  • The dry fronds of deciduous ferns protect the base of the plant.

Once the cute, curled fiddleheads show in spring, clip off old fronds at the soil line.

Hardy ferns for the garden

Christmas fern: Evergreen, hardy and great for north-facing slopes.

Cinnamon fern: Tall, reddish-brown "cinnamon stick" fronds followed by tall green ones.

Japanese painted fern: Silvery fronds tinged with red and blue; a great foliage plant for the shade garden.

Japanese red shield fern: Coppery young fronds mature to green, with red spores.

Maidenhair fern: Dark stems and feathery fronds; needs constant moisture.

Ostrich fern: Tall plumes; likes marshy soil beside garden ponds.

Tender ferns for containers

Bear's-foot and hare's-foot ferns: Long,"furry" rhizomes at base of fronds; great for hanging baskets.

Bird's-nest fern: Rosette with lobed, flat fronds; easiest fern to grow as a houseplant.

Boston fern: Easy to grow in outdoor hanging baskets; sheds badly when brought indoors.

Japanese holly fern: Shiny, leathery foliage; easy to grow as an indoor-outdoor patio plant.
