How to Grow and Care for Hardy Ferns

Ferns come in a diverse range of texture, color, sizes and and shapes.
Their ease of care and diversity of attributes make them an essential part of any well rounded garden.

Willy the Garden Gnome In their native environment, most hardy ferns thrive in the dappled shade of the woodlands and forests, growing in rotted leaves and other natural compost.
Deciduous ferns should be trimmed as the fronds yellow in late fall and early winter.
Older or damaged fronds of hardy evergreen ferns can be trimmed off in late winter or early spring,
just before the new fronds emerge. At the same time, apply a new layer of mulch for the new growing year.

Planting Hardy Ferns

The best time to plant hardy ferns is during the spring and fall when the rain is plentiful.
Cultivate the soil thoroughly, adding a good portion of compost into the planting hole before you plant your fern.
Ferns are shallow rooted plants and should be planted with their crown flush with the surrounding soil.
Keep garden debris away from the crown of your ferns if you can.

Growing requirements for Hardy Ferns

Ferns require good drainage, so if your soil is very heavy with clay, it may be necessary to raise the soil level a few inches, or mix in sand to prevent crown rot. Most hardy ferns grow well in partial shade or indirect sunlight, but there are many of them that will do well in full sun, as long as they get enough water.
More than anything else, ferns need both sufficient moisture and good drainage. Whenever possible, water the roots and not the fronds.
Your ferns will appreciate an annual spring top dressing of chopped up fronds, well rotted-compost or manure.
Every 2 or 3 years, you can dig up and divide your ferns into several new plants.
