Sporting lacy, elegant, textured fronds, the lady fern is sure to make a statement wherever you plant it. This plant has fronds that are a vibrant green throughout the summer and turn golden-yellow after the first frost. Lady fern stalks can be green, red, or purple. These support a multitude of tiny leaflets, which gives the lady fern its feathery, lacy appearance. It’s no surprise that this fern is often used in floral arrangements to add texture and create a vibrant backdrop. Their fiddleheads can even be used in recipes as a nutritious green. Keep the soil moist, but not soggy. However, don’t stress if you forget to water them for a time; the lady fern springs back from neglect very well. After the first frost, the foliage will die off. At this time, trim away the foliage and dispose of it. New, fresh foliage will appear in the spring. Besides this, the lady fern does not require pruning or other maintenance.
Light
Because the lady fern thrives in shaded woodlands or swamps, these plants need shade in your garden as well. Shade to partial sun is best. Be sure to keep them out of harsh midday and afternoon sunshine.
Soil
Creating soil that mimics the rich, moist, well-draining soil in lush woodlands and meadows is ideal. Theses plants appreciate sandy, humus soil because of its ability to drain well. Adding compost or other decaying organic matter will round out your soil, making the ideal environment for your lady ferns.
Water
Consistent watering is important for lady fern plants. If these ferns dry out, they become brown and wilted. However, despite their dismal looks, the lady fern springs back very well. With some watering and care, these plants will become lush again. Aim to keep the soil evenly moist, but not soggy. This is most important during the plant’s first year. Once established, the lady fern is quite hardy and can tolerate periods without water.
Temperature and Humidity
The lady fern thrives in naturally humid, moist areas, so high humidity will keep these plants green and lush. If you are attempting to keep your lady fern indoors, be sure to provide them with adequate humidity by misting or using a pebble tray. They are quite hardy when it comes to temperature, growing in zones 3 to 6. For warmer climates, zones 7-9, chose the Southern Lady Fern (Athyrium filix-femina var. asplenioides) which will withstand the high temperatures.
Fertilizer
Compost is the perfect soil amendment for lady ferns. This provides the richness and nutrients that the lady fern needs. Adding other organic material, such as leaves, is another great option. Slow-release fertilizer can also be used, but be careful with other fertilizers. The lady fern is easily harmed by too much fertilizer. Sticking to compost or slow-release fertilizer is safest. Give this once in the spring to encourage new growth.
Pruning & Harvesting
In spring, lady ferns send out fiddleheads, which are the young sprouts of its large fronds. These curled fiddleheads are edible and are similar to asparagus; removing some fiddleheads can even encourage more abundant growth. To harvest, cut the fiddlehead close to the soil and remove its papery sheath. However, be sure not to take all the fiddleheads, since this will weaken the plant. Before harvesting any plant, always be sure to properly identify it. Once identified and harvested, be sure to properly cook before consumption.
Propagating Lady Ferns
The best way to propagate your lady fern is through the division of rhizomes. This can easily be done in the spring.
Potting and Repotting Lady Ferns
The lady fern can be grown in containers inside and outside, but indoor conditions make it a bit tricky to mimic the humid, moist conditions that these ferns like. They do not generally do well with dry, indoor air. To successfully grow a lady fern as an indoor plant, keep it away from drafts and vents, and mist the foliage daily. Placing this plant near the kitchen sink, in a bathroom, or on a pebble tray will also help increase the humidity. Though they can get large, lady ferns prefer small pots. Once the rhizomes no longer fit in the pot, simply divide them. To grow lady ferns in containers outdoors, be sure to choose a pot or basket that allows for sufficient drainage. It may also be beneficial to use a fern-specific potting medium.
