Care Guide
Planting
Plant your Serpentine Lace Fern in full sun to part shade in well-draining soil that mimics its native rocky mountain habitat. This fern thrives in serpentine soils and rock crevices, so prioritize excellent drainage above all else - think gritty, mineral-rich potting mix if you're growing it in a container. Space it where it won't compete for moisture during California's dry season, since it naturally grows on slopes where water moves through quickly.
After Planting
Water regularly during the growing season to keep the soil seasonally moist, mimicking the moisture pattern of its native rocky slopes. Once established, this fern is adapted to handle drier periods and shouldn't need frequent supplemental watering if planted in the right spot. The #1 mistake is overwatering or using dense, moisture-retentive soil - this fern wants excellent drainage and will rot in soggy conditions.
