Light watering
She needs very very little water. About once a month is fine. Water the soil, not her leaf, to keep her healthy.
Bright light
She’ll be ok in light shade, but does better in brighter light. Constant direct sun may be too much, but a bit is fine.
Dusting
She needs minimal care, but if you see her get dusty, very gently wipe it off. Use something like a soft, dry brush.
