liquid green plant or fern fertilizer at half strength
-
stop or significantly reduce fertilizing in winter, as the plant is resting.
🌱 Substrate
A humus-rich and moisture-retaining, but loose soil climate is important:

humus-rich

good water retention capacity, but air permeable
-
slightly acidic
A high-quality potting soil, possibly loosened with some perlite, works perfectly.

every year or every 2 years in spring

when the pot is completely rooted through, transfer to a slightly larger container.

please do not cut the tips of the fronds (they will then no longer grow)

🌱 Propagating Nephrolepis exaltata Green Lady
Propagation is quite simple and best achieved by division:

carefully divide the root ball with your hands or a sharp knife when repotting

🧠 Other Care Tips

The plant loves room temperatures around 18–22 °C and is sensitive to cold drafts.
