Thanks to Patti R., who recently sent me a question about a confusing orchid care article. Patti was understandably stumped by a gardening column in a normally reliable California newspaper. The column has repeatedly advised Phal growers to water their plants only once every 3 weeks. Patti asked: I know this can’t be right. I […]
I’ve already blogged about my objections to watering orchids with ice cubes. It doesn’t take a degree in botany to see that tropical plants, especially warm growers like the Phal in the first photo below, don’t like cold temps. But there’s another, less obvious reason why ice isn’t right for orchids — ice cubes don’t […]
Orchid care changes with the seasons. Growers need to adjust for winter’s approach in the Northern Hemisphere. Orchids with pseudobulbs are entering dormancy. If they sport swollen stems like those in the first photo below, they may only need water once or twice per month over winter. Too much water can cause rot, or mess […]
As Halloween quickly approaches, it’s the perfect time for a few creepy carnivorous plants. They’re helpful orchid allies, providing superb natural pest control, and they make great green alternatives to toxic pesticides. Bug-eaters come in many forms. Most famous are Venus Fly Traps, but there are also hundreds of varieties of pitcher plants, and many […]
Are you an allergy sufferer who fears that your nose has confined you to a life of plastic flowers? Orchids may be the answer. Allergic reactions to orchids are rare because they don’t have airborne pollen. Instead, their pollen clumps in waxy little balls called pollinia. Since it doesn’t float freely in the air, it’s […]
If you think that orchids are all delicate and fragile, here’s a hardy Australian mini that will surprise you. This Sarcochilus is one tough species, related to Phals and Vandas. In the wild, it grows as a lithophyte, or rock plant. Its roots attach to cliff faces in eastern Australia, and they hold on despite […]
Spring is on the calendar. Even if your part of the world hasn’t completely shed winter, the sun is stronger, the days are longer, and it’s time for some seasonal orchid chores: Move orchids from their brighter winter locations to shadier areas for spring and summer. Orchids should receive enough light so that leaves are […]
Orchid pros sometimes say that you’re not an orchid expert until you’ve killed your weight in orchids. Since I started growing them 20 years ago, I believe I’ve passed that benchmark, and here’s another for the scales. This African orchid, a Polystachya, looked fine in these 2006 photos. I bought this unusual specimen years ago […]
Pruning orchids is easier than pruning roses or hydrangeas, because orchids don’t need shaping. Instead, pruning serves to remove dead or damaged parts of the plant. Dead leaves, flowers, or roots should be removed before they attract pests or disease. Pruning is sometimes necessary when dividing and repotting an orchid. Start by cleaning sharp garden […]
Growing orchids in cold northern climates brings extra challenges in winter. First, cold temps mean that heaters run frequently, drying the air in the process. Low humidity can cause lots of problems for orchids, such as wilting blooms, pests, and disease. Tried-and-true methods to raise humidity include: Grouping plants together Placing orchids in humid areas […]
