Troubleshooting
Tatting Fern problems — and how to fix them
Tatting Fern (Athyrium filix-femina 'Frizelliae') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frond browning at tips and edges
The narrow, bead-like pinnae of Tatting Fern desiccate more readily than typical broader fronds. Ensure consistent moisture, raise humidity, and protect from draughts. Trim browned frond ends with clean scissors to maintain appearance.
Slugs on emerging croziers
Outdoors, slugs and snails target the emerging croziers in spring, rasping out the center of new growth. Protect emerging fronds with copper tape around pots, or apply iron phosphate pellets in the surrounding soil. Inspect at night during wet periods.
Loss of distinctive pinnae shape
Occasionally, this cultivar may produce atypical fronds reverting toward broader pinnae. This is a form of sporting. Remove any reverted fronds at the base to encourage typical tatting-like growth. Ensure the plant is correctly labeled as this cultivar on purchase.
