Onychium is a plant genus that typically favours partially shaded areas with favorable humidity and well-drained soil. It requires regular watering, limiting exposure to direct sunlight, and continual ambient temperatures to flourish. These ferns may face challenges from pests like aphids, scale insects, and certain fungi, which can cause issues such as leaf discoloration and stunting of growth. Seasonally, onychium plants require additional monitoring and slight adaptations in care - less watering in the winter, and extra moisture during hot summer periods to prevent drying out.
