Orchid Care: Ice Cubes, Cola, and Moss Top-Dressing

Debunking Orchid Watering Myths

A shop advised one ice cube weekly on moss-covered medium for a new orchid. Also, is leftover cola good for houseplants?

Orchid Watering

• Never use ice cubes: Freezing water shocks roots. Orchids prefer tepid, soft water (bottled if tap is hard).
• Light: Bright indirect, 10+ hours daily. Summer outdoors in warmth.
• Feed: Summer months. Repot every few years; they like being pot-bound.

Cola on Plants

No evidence cola benefits plants. Its sugar and acidity likely harm soil biology. Moss top-dressing may be decorative or for moisture retention—ask the seller.
