It could be due to dry air, or too much sunshine.

It sounds like your Rabbit's Foot plant might be experiencing some stress. Crispy, orange edges can be a sign of overwatering or underwatering, so double-check your watering routine. Make sure the plant's soil is well-draining and not staying soggy. Overfeeding can also cause issues, so review the amount and frequency of fertilization. Additionally, consider if there have been any changes in light or temperature conditions. If everything seems consistent, you might want to gently trim away the affected parts and monitor the plant's response to adjustments in care.
