Many people believe that orchids should be watered a few times a week, since they come from tropical forests. Unfortunately, such treatment will kill very soon the plant’s roots.
The general watering rule
Orchids grown in pots are watered once every 5 to 12 days, depending on the type of orchid, temperature and time of the year.
During summer, when the days are longer and warmer, it’s necessary to water the orchid more often than in winter.
Special watering rules
According to water needs, orchids are classified as it follows:
1. Orchid varieties whose substrate must be kept well-moistened all the time (but without water pouring!): Paphiopedilum, Miltonia, Cymbidium, Odontoglossum.
2. Orchid varieties whose substrate must be kept moist during periods of intense growth and which must be allowed to dry between watering for the rest of the time: Cattleya, Oncidium, Brassia, Dendrobium.
3. Orchid varieties whose substrate must be allowed to dry almost completely before new watering: Phalaenopsis, Vanda, Ascocenda.
It’s best if you know the orchid species very well and its care needs.
Orchids (and all potted plants) are a real treasure in the house if you can adjust a little bit its environmental conditions.
