Light
Calathea (Prayer Plant family) tolerates: medium / indirect. Put it within a few feet of a window; a dark corner will make it weak and leggy.
Watering
Keep lightly moist with filtered or rain water. Tap water often causes crispy edges.

Top tips
- Crispy brown edges = dry air or minerals in tap water.
- Never in direct sun — the patterns fade.
- Group with other plants to raise humidity.
