About the orchid

With over 25,000 species, orchids grow on every continent except Antarctica, many of them perched on trees in tropical forests rather than in soil. The common moth orchid sold as a houseplant produces arching sprays of long-lasting flowers and, with the right care, will rebloom year after year.

Orchid FAQs

How often should I water an orchid?

Most moth orchids need watering about once a week — when the roots turn silvery and the mix is nearly dry. Overwatering, which causes root rot, is the most common way orchids are killed.

Do orchids rebloom?

Yes. Moth orchids can rebloom for years. After the flowers drop, cut the spike just above a node to encourage a new bloom, and give the plant good light and care.

Why are my orchid’s leaves turning yellow?

A few yellow lower leaves can be normal aging, but widespread yellowing often signals overwatering, too much direct sun, or root problems.
