Water
The Hymenophyllum Lyallii prefers moist soil, so it is important to keep the soil evenly moist. Water the fern regularly, but be careful not to overwater it, as this can cause root rot. The best way to water the fern is to pour water into the pot until it begins to drain out the bottom. This ensures that the entire root system is watered.
