With a San Francisco rainy winter kicked into gear, the Cymbidiums in the back garden have bloomed right on schedule. About 50 Cymbidium species are native to an area from India to Japan, and south to Australia.

Take the opportunity to clean off dead leaves and weeds. Check for pests, paying attention to the undersides of leaves and the potting media. Although I try to [...]

Stenoglottis longifolia grows [...]
Orchid care changes with the seasons. As fall approaches, it’s time to adjust water, fertilizer, light, and temperature.
If warm growing orchids have been kept outside for the summer, it’s time to bring them indoors. Phals, Cattleyas, and Vandas should be checked for pests, and then brought inside before nighttime temperature become too cold.
