Complete Fern Care Guide

Indoor Fern Basics

Ferns need indirect light, consistent moisture, high humidity, and monthly feeding spring‑fall.

Light

North window ideal. Direct sun burns fronds. Day 65‑75°F, cooler at night. Avoid cold drafts.

Moisture & Humidity

Keep soil evenly moist—never soggy. Finger test: dry → water; wet → wait. High humidity essential: pebble tray or humidifier.

Feeding

Liquid houseplant fertilizer monthly late spring through fall. Withhold in winter.

Transplanting & Propagation

Divide and repot every couple years in spring. Propagate from spores: collect brown spores from frond backs, dry in paper bag, sow on seed‑starting mix.
