How Do You Repot a Gold 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 Gold Fern?

Gold Fern can be propagated through spores, division of rhizomes. Similar propagation techniques also apply to sulphur fern plant care, which shares the same genus.
