Crested Surf Fern
Microsorum punctatum
Microsorum punctatum, commonly known as the Crested Surf Fern, is a unique epiphytic plant native to tropical regions of Africa, Asia, and Oceania. It stands out from other ferns with its stiff, upright, and leathery green fronds that often terminate in intricate, branched or crested tips. These 'crested' edges give the plant a wavy, flame-like appearance. Highly adaptable and structurally robust, it is a popular choice for indoor gardeners looking for a fern that is slightly more resilient to varying household conditions than the more delicate species.

Care Guide
Watering
Keep the soil consistently moist but avoid waterlogging. Unlike many sensitive ferns, the Crested Surf Fern can tolerate the top inch of soil drying out slightly between waterings, but it should never be allowed to dry out completely. Use room-temperature filtered water to prevent shock.
Light
Thrives in bright, indirect light. It can tolerate medium light conditions, but growth will slow. Direct sunlight must be avoided as it will scorch the glossy fronds and cause bleaching.
Humidity and Temperature
As a tropical species, it prefers high humidity levels above 50%. Use a humidifier or a pebble tray to maintain moisture in the air. Keep the plant in a warm environment between 60°F and 85°F (15°C - 30°C) and away from cold drafts or heating vents.
Soil and Repotting
Use a well-draining, airy potting mix. A blend of peat moss or coco coir with perlite and orchid bark works best to mimic its natural epiphytic habit. Repot every 2-3 years when the rhizomes begin to crowd the pot.
Common Issues
Yellowing fronds usually indicate overwatering, while brown, crispy tips are a sign of low humidity. Watch for scale insects which can hide on the undersides of the leathery leaves.
