The leaves are leathery and have a shiny, waxy texture. The spores of Microsorum ferns appear as small, brown dots on the underside of the fronds.

Care Guide

Water: Microsorum ferns prefer to be kept consistently moist but not waterlogged. Water them when the top inch of soil feels dry.

Fertilization: Feed Microsorum ferns with a balanced, water-soluble fertilizer every two weeks during the growing season.

Soil: Plant Microsorum ferns in well-draining soil that is rich in organic matter.

Sunlight: Microsorum ferns prefer bright, indirect light. Direct sunlight can scorch their leaves.

Hardiness Zones: Microsorum ferns are typically grown as houseplants, but some species can be grown outdoors in USDA hardiness zones 9-11.
