Use the plant's normal watering, light, drainage, humidity, pest, and temperature preferences before treating this symptom as a generic problem.
For boston fern, adjust the diagnosis around this plant profile: Boston ferns dislike dry air, missed watering, and hot drafts. Crispy fronds usually point to moisture stress, but yellowing with soggy soil can still mean root stress.
Check soil moisture below the surface before watering again.
Compare the symptom with this plant's known weak points.
Look for a recent move, repot, temperature change, or pest clue.
Check pot weight before fronds crisp at the edges.
Move away from heat vents and dry windowsills.
Stabilize care and avoid stacking several fixes at once.
Use the analyzer if the symptom is spreading or mixed with other signs.
Read the related guides before repotting, fertilizing, or pruning heavily.
