Water the Orchid (Phalaenopsis) about once every seven to ten days, allowing the potting medium to dry slightly between waterings. Pour room-temperature water over the bark until it drains freely, and never let the Orchid sit in standing water inside a cabinet or saucer. The Orchid needs less water in winter, when watering every ten to fourteen days is usually enough. Roots that turn silvery-grey signal that the Orchid is ready for its next drink, while plump green roots mean it has enough moisture. Overwatering is the most common cause of root rot in the Orchid, so err on the drier side.
Place the Orchid (Phalaenopsis) in bright, indirect light, such as near an east-facing window where morning sun is gentle. The Orchid will scorch under direct midday sun, so filter strong light through a sheer curtain. Leaves that are a healthy grassy green indicate the Orchid is getting the right amount of light. Dark green, floppy leaves mean the Orchid needs more light, while yellow or reddish leaves suggest too much. A spot with twelve to fourteen hours of daylight encourages the Orchid to rebloom.
The cited reference does not list Orchid (Phalaenopsis) as toxic to cats or dogs. The cited reference does not list Orchid as toxic to horses. Because the cited reference is silent about other animals, watch how a pet reacts around the Orchid and contact a veterinarian if your animal shows unusual symptoms. If a child or pet ingests part of the Orchid and you are concerned, call your local poison-control or veterinary line for guidance. This entry reports only what the cited reference states about the Orchid and does not certify any outcome.
Pot the Orchid (Phalaenopsis) in a coarse, free-draining medium such as graded fir bark rather than ordinary houseplant soil. Repot the Orchid every one to two years, ideally just after flowering finishes, to refresh the bark before it breaks down and suffocates the roots. Choose a clear or slotted pot so you can see the Orchid's roots and check moisture at a glance. When repotting, trim away any soft, brown, or hollow roots and keep the firm pale ones. A pot only slightly larger than the old one keeps the Orchid from staying too wet.
The most common problem with the Orchid (Phalaenopsis) is root rot from soggy bark, shown by mushy brown roots and wilting leaves. Wrinkled, leathery leaves on the Orchid usually mean underwatering or dehydrated roots rather than too much water. Bud blast, where flower buds yellow and drop before opening, happens when the Orchid faces drafts, sudden temperature swings, or dry air. Sticky residue or small white cottony spots can indicate mealybugs or scale on the Orchid, which you can wipe off with a cotton swab dipped in diluted alcohol. If the Orchid stops blooming, a drop in night temperature of about ten degrees Fahrenheit for a few weeks often triggers a new flower spike.
