Doryopteris Cordata

What is the plant

Doryopteris cordata, called the Antenna Fern, is a tropical, evergreen fern displaying lobed, leathery-green foliage. Forms a low, ground-hugging mound except for fertile fronds that stand well above the foliage. It’s a great choice in a terrarium, as a houseplant or an annual in most landscapes. Ferns thrive in neutral to acidic, loose, richly organic soil which is moist but not waterlogged. Prefers bright, filtered sunlight and is excellent as a houseplant or in a seasonal container. Protect from freezing temperatures!

How to Care for the Plant

Water
Keeping a fern hydrated takes a little effort, and this plant thrives on humidity. Indoor growing conditions can often be dry, especially due to winter heat. Mist the plant daily, focusing on the arching stems. If the plant appears to be turning brown and droopy, it likely needs more water. While the asparagus fern can dry out to the point of appearing dead, it likely isn't. Warmer, humid air and daily misting will help revive it. Outdoors, keep asparagus fern well watered to prevent the soil from completely drying out.
Pruning
Ferns are fast growers, and you may want to trim yours to keep it tidy. Conversely, it's okay if you want it to look wild and shaggy. Use clean garden shears or sharp scissors to give your plant shape.
Fertilizer
Feed fern with liquid or water-soluble all-purpose plant food diluted to half strength. During summer, the plant may need weekly feedings; otherwise, feed monthly.

Sunlight
The antenna fern thrives in dappled shade, although it can be acclimated to more light. Keep it out of direct, bright sunlight.
Soil
Plant antenna ferns in pots or containers in loose, well-drained potting soil. Outdoors, plant it in rich, well-drained soil that is slightly acidic. It is generally tolerant of less-than-ideal soil conditions.
Temperature
Try to maintain a warm temperature (around 70 degrees Fahrenheit) and not dip below 55 degrees Fahrenheit for too long. If you have a shady porch outside, or a greenhouse, the indoor plants will likely respond with abundant growth over the summer.
