Cymbidium

Tuesday, December 15th, 2009

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. They have been symbols of virtue and friendship in China since Confucius praised them 2500 years ago, and [...]

Sobralia

Friday, November 20th, 2009

Sobralia flowers never fail to  impress. Many species in this genus have big blooms. With flowers as large as 10 inches (25 cm,) this species is one of the most remarkable in the family.

The flowers look like Cattleyas, but the similarities end there. Unlike Cattleyas, this Sobralia species likes heavy water and fertilizer, and doesn’t [...]

Autumn Orchid Chores

Saturday, September 26th, 2009

Depending on your local climate, autumn brings shorter days, cool temperatures, and some corresponding autumn chores. As temperatures dip, you’ll need to bring warm growing orchids inside.  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 [...]

Compost Happens

Saturday, July 25th, 2009

The best methods to fertilize orchids are constant subjects of debate. Many orchid experts subscribe to the maxim “weakly, weekly,” meaning that a weak mixture of fertilizer given on a regular basis can go a long way to improving orchid growth and blooms. With my own orchids, I’ve used specialized orchid fertilizer, diluted regular plant [...]

Orchids need healthy leaves to survive and thrive. If your orchid’s leaves look unhappy, take this list of common problems as a starting point to your diagnosis.

It helps to pay attention to the look [...]

Cymbidiums are popular orchids, and here on the California coast, Cymbidium blooming season has started. This yellow one, possibly Cymbidium Golden Elf ‘Sundust,’ is a hybrid of Cymbidium ensifolium, which has traditionally been grown in China, Korea, and Japan for centuries.

To grow these beauties with their sweet, richly scented flowers, you need to provide an [...]

Don’t Overwater

Monday, November 3rd, 2008

More people kill their orchids through overwatering than any other cause. Fall is particularly perilous time for overwatering, as plants start to go dormant, but people unwittingly continue the same watering regimen as they did in the growing season. With too much water, orchid roots will rot, and the leaves will follow. So this is [...]

South African Orchid

Thursday, October 9th, 2008

If you saw this unusual Stenoglottis orchid growing in its native home in South Africa, and it wasn’t in bloom, you would probably think it was an ugly weed. If you saw it in bloom, though, I’d bet you would be amazed at its masses of dainty purple polka-dotted flowers with fringed lips.

Stenoglottis longifolia grows [...]

Preparing for Fall

Saturday, September 13th, 2008

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.
Orchids that go [...]

Big Flower

Tuesday, September 9th, 2008

The title pretty much says it all. The scientific name of this orchid, Sobralia macrantha, translates as “big flower,” and it doesn’t disappoint. This easy-to-grow orchid puts on a great show with flowers that can be as large as 6-10 inches (15-25 cm.) It’s native to a variety of habitats from Mexico to Costa Rica, [...]
