How Do You Repot a Sulphur Fern?
Repot every 1-2 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Sulphur Fern?
Sulphur Fern can be propagated through spores, division of rhizomes. Similar propagation techniques also apply to gold fern plant care, which shares the same genus.
