Orchids generally should be watered about once every 7 to 11 days, or roughly once a week, depending on the environment and the moisture level of the growing medium

. The key is to water only when the potting mix is dry, as overwatering is the most common cause of orchid problems like root rot and crown rot

. Here are some important tips for watering orchids:

• Check the roots or potting media before watering. Roots that appear silvery or the potting mix that feels dry indicate it’s time to water, while green roots or damp media mean you should wait

• Water in the morning to avoid water sitting on the plant overnight, which can cause rot

• The frequency may vary with factors such as light, temperature, humidity, and season. Orchids need less water in winter and more in warmer, brighter conditions

• A common method is to soak the orchid in water or pour water over the potting mix until it drains out the bottom

• Some growers use ice cubes (about three for a 5-6 inch pot) as a slow-release watering method once a week, but always check moisture levels first to avoid overwatering

In summary, watering once a week is a good general guideline, but always base watering on the dryness of the potting mix and the condition of the roots to keep your orchid healthy
