Last week’s wacky weather wasn’t limited to a mini heatwave; we also had a hailstorm. San Francisco’s mild weather seldom falls below freezing, but winter storms occasionally bring hail. It rarely does damage in our garden. After a powerful storm was punctuated by noisy hailstones, I saw that the leaves of the Brugmansia had been […]
Often I like to point out that many orchids are easy to grow, but some varieties deserve their difficult reputations. For example, this purple and white Comparettia ranks as one of the fussier members of the orchid family. It may resemble a simple Oncidium, but don’t be fooled. Cultivating these blooms takes some work. This Comparettia […]

Orchid growers on the coast, like me, normally take advantage of the cool fog flowing off the Northern Pacific to maintain good humidity. Those moderate conditions allow many orchid varieties to grow outdoors all year. […]
As the days grow longer with spring, the season brings some orchid chores, including repotting. Orchid repotting can be intimidating for beginning growers, so in addition to the basics, I have a few more hints to help: Orchids that have just finished blooming often enter a cycle of new leaf and root growth.
