Orchids generally should be watered about once every 7 to 10 days, or when the potting medium feels dry. This timing can vary depending on factors like the type of orchid, the potting medium, light exposure, temperature, humidity, and the season

. Key points for watering orchids:

• Water when the potting mix is dry to the touch or when the roots turn silvery-grey (green when wet)

• Avoid overwatering to prevent root rot and crown rot; orchids prefer to dry out somewhat between waterings

• Morning watering is recommended so any water on leaves can evaporate during the day, reducing risk of rot

• Water thoroughly so that water runs through the drainage holes, then let the pot drain completely

• Frequency may be weekly in winter and possibly more often in warmer, drier conditions or brighter light

• Using pots with good drainage and fresh potting mix annually helps maintain healthy roots and proper moisture levels

In summary, check your orchid’s roots and potting medium moisture, and water roughly once a week or when dry, adjusting based on your environment and plant needs.
