To answer Jimboborchid's questions, the shadow on the wall is from the camera flash. I think it's getting enough sun light, but is under-watered, as the roots are wrinkled and crispy. I usually water only once per week, and medium is pretty dry by that time. I let it soak in water for 20-30 minutes, and let it drain completely before putting it back to the decorative pot. The medium is orchid bark. Shall I water more often?
