What Soil Mix Works Best for a Climbing Fern?
Loose, well-draining potting mix with high organic content. Good drainage is essential for Climbing Fern to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Climbing Fern?
Feed Climbing Fern every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.
Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.
How Do You Repot a Climbing 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 Climbing Fern?
Climbing Fern can be propagated through spores, division of rhizomes. Similar propagation techniques also apply to kangaroo fern plant care, which shares the same genus.
