Asplenium Antiquum also known as “Bird’s Nest Fern”, develops an upright rosette of long, Lance-shaped fronds, with shiny leaves that have a ruffled, wavy edge and striking silhouette, giving it a highly decorative appearance. Initially the fronds of this asplenium are a light lime green, however they soon mature to a deeper, richer green.
Indirect light. Avoid direct sunlight.
Water around the edge of the center rosette to avoid the water becoming stagnant in the center, which may cause rot. Water once or twice a week.
A peat-based mixture with organic material is required.
Tough ferns, such as bird’s nest ferns, can survive with humidity levels from 30 to 50 percent, although added humidity from a humidifier or daily misting will help prevent the fronds from turning brown on their edges.
The bird’s nest fern will thrive in a warm area. Keep the temperature between 16 to 24 °C
Once or twice a month using an organic fertilizer.
Bacteria Blight – Translucent spots develop all over the leaves, enlarge quickly and turn reddish-brown with purple halos. Avoid overhead watering.
Foliar Nematode – Small dark green spots form at the base of fronds. Spots turn brown to black as they enlarge. Avoid wetting the fronds when watering.
Leaf Tip Burn – Tips of fronds and leaflets brown and die. Over-fertilization. Reduce the amount of fertilizer being used and leach the pots.
Pythium Root Rot – Plants have a gray color or are yellowed, stunted, and wilted. Roots are brown and rotted. Plant in pathogen-free pasteurized potting mix. Apply a fungicide to protect plants.
