People often ask me whether to water their orchids with ice cubes. While I know using ice can work for some orchids, I advise against it. Cold water can damage flowers, leaves, and roots. Most commonly sold orchids originate from the tropics, where they never experience anything close to freezing temps. Even orchids that come [...]

Corresponding to a dry season in the wild, members of these common orchid families are resting like a bear in a cozy den. Resist the urge to water until you see their pseudobulbs start to shrivel. Do your [...]

About 50 Cymbidium species are native to an area from India to Japan, and south to Australia.

Dave’s macro photography skills make it possible to really [...]
