Watering – Orchids need good drainage, so remove wrapping paper or decorative containers before watering. Soak the plant with room-temperature water, and let all excess drain out. Don’t let the flowerpot sit in water for too long, or the roots may rot.

Humidity – Orchids want high humidity. Dry air wilts flowers and attracts pests. To increase humidity, group plants together, or put plants in a humid area, like a bathroom or kitchen. Use a cool mist humidifier, or a spray mister. Place flowerpots in trays of shallow water, keeping the pots raised above the water level on a layer of pebbles or an inverted saucer.

Light – Place orchids in bright light, but keep out of full sun while you’re enjoying the flowers.

What kind is it?Moth Orchids, in the first row of photos above, are the most popular. Cattleyas are in the second row of photos, and are longtime favorites. The third row shows Lady Slippers, and the fourth row shows Dancing Lady Orchids. All are available in different colors, patterns, and sizes, so use pictures as general guidelines, not strict standards. Find more pictures and more tips at AboutOrchids.com.

Why ‘Plant Blindness’ Matters

“Plant blindness” is a tendency not to notice plants. People are generally much better at noticing animals. With increased urbanization, and more time spent looking at screens, the problem has worsened. Most don’t appreciate how important plants are, and that weakens support for plant conservation. As orchids and other plants face extinction, protecting them is often an afterthought. “Plant conservation matters for environmental health. But it also matters, ultimately, for human health.” Fortunately, there are solutions. “Although our human brains may be wired for plant blindness, we can overcome it with greater awareness,” says botanist Elisabeth Schussler. It’s helpful to interact with plants every day. That includes noticing plants, and also talking about them. It benefits all of us, and the planet, too.

Orchids in Our Spring Garden

After a rainy winter, our spring garden has burst into bloom, with orchids and more. The first two photos are not orchids: a very tough red rose and a brilliant yellow and white Tidy Tips. We didn’t know the rose was in our backyard for a few years, since it was completely encased by a large rosemary bush. One day the rosemary bizarrely produced a big red flower, and I discovered the rose. Considering it receives no summer water at all, it’s one tenacious plant. The delightful Tidy Tips is a native California species, and grows easily from seed here on the Northern California coast.

Many of these orchids may be familiar to regular readers. They’re all growing outdoors, exposed to the elements. I’ve had these plants for years, except for the white and yellow Laelia anceps ‘Helen’ shown in the previous row. I bought that one at an orchid show last year, and it’s proving to be just as hardy as its purple cousin in the third picture in that row.

Sarcochilus, Dendrobiums, Masdevallias, and Cymbidiums have been reliable bloomers in our garden. Our mild coastal climate simulates a mountainous cloud forest environment so well that they thrive here. It ensures that we can enjoy lots of orchids in our spring garden.

The Little Orchid That Could

This little orchid is certainly not the showiest, or the most colorful, but it’s a survivor. I blogged about this mini Cynorkis a few years ago, when I thought I might have killed it. Actually, it was fine, and grew again without problem. In the years since, whenever I’ve worried that I might have done it in, it’s always come back with fresh leaves and blooms.

This species seems to go dormant on its own schedule, dropping its old leaves and then growing new ones from tiny tubers. The small flowers open successively, extending the bloom for a couple months. It’s the perfect mini for a warm, shady spot, as long as the space can accommodate the tall flower spikes, which can reach 2 feet (0.6 m) tall or more.

Although I’ve gotten used to its seemingly random dormancy schedule, there was another time when I really thought I had killed it. It had a fresh set of leaves, and I must have accidentally overwatered it. The leaves quickly rotted, and I assumed the plant was finally lost. Instead, it started growing again after a few weeks, no worse for wear. This Cynorkis is truly the little orchid that could.

Happy, Healthy Orchid Roots

Healthy roots are essential for healthy orchids. Many people are tempted to cut off their orchid’s roots because they seem unattractive, but that’s bad for the plant. Whether they’re air plants or terrestrials, orchids need happy roots to survive and thrive. Some types have thick roots, while others have thin. All have central, wiry cores, surrounded by outer layers of absorbent cells called velamen.

This outer layer is white or greenish-white, with light green growing tips. Roots may also be brown from growing media or red from sun exposure. Healthy roots are firm, and essential to absorb water and nutrients. Mushy or hollow roots are dead and should be removed, a task which is often done during repotting.

Moth Orchids and Vandas are popular varieties which like to have their roots in the open air. In the wild, they anchor to tree trunks and branches to live as air plants. Others don’t mind growing in small, crowded pots. To grow well, they all need good humidity and breezes to keep the air moving. Some types have chlorophyll in their roots, which photosynthesize along with the leaves. Happy, healthy roots can give an orchid the energy for great blooms.
