Orchids generally should be watered about once every 7 to 10 days. The frequency can vary depending on factors like the season, light exposure, humidity, and temperature. Typically, orchids are watered once a week in winter and up to twice a week in summer. It is important to water them just as the potting medium dries out to avoid both overwatering and underwatering, which can harm the plant. Morning is the best time to water orchids to allow them to absorb moisture during the day. The amount of water should be enough to moisten the soil without causing sogginess—usually about a quarter cup. Methods include watering over the soil, soaking the pot briefly, or misting, with watering over the soil or soaking being the most effective. Always ensure good drainage to prevent root rot. In summary:

• Water every 7-10 days or when potting mix is dry.
• Water more in warm, dry conditions; less in cooler, humid conditions.
• Avoid waterlogging; orchids prefer to dry out slightly between waterings.
• Water in the morning for best absorption.

These guidelines can be adjusted based on your specific orchid type and local environment.
