The internet is loaded with gardening advice—good, bad, and atrocious. But excellent online information is available, so it’s worth spending the less-demanding gardening months poking around online. Here’s a sampler of what’s out there in the way of classes, webinars, and podcasts from reliable experts who can help you make the most of your next […]
At this time of year, many greenhouse owners are getting ready to start seeds. I find that pepper seeds take up to three weeks to germinate, so I usually start them first, followed by eggplants, tomatoes, and flowers. However, there’s a problem starting heat-loving plants in a small greenhouse in late winter. The seeds of […]
When the city has only the colors of brick, slush, and concrete, green is precious. That’s why we plant evergreens. Just about every yard I see has some evergreen tree or shrub. There are tiny tidy boxwoods in pots. There are towering spruces. There are rows and rows of arborvitaes, the go-to plant for privacy […]
We’re living in interesting times – honestly, I wish the days were rather more dull. In Colorado along the Front Range where I garden (fitfully it must be admitted), records from 1 July to 17 December report just 1.07 inches of rainfall in Denver. In Colorado Springs, we’ve had a few drops and some snowflakes […]
This is the time of year when we can imagine our gardens of the future. But how do we know which plants to choose? Today, I’m turning to Janet Sluis, Director of Plant Development Services and the curator of plants in the Sunset Plant Collection and the Southern Living Plant Collection. Essentially, she auditions plants. […]
The steppe-like conditions in my garden – with no rain for the past few months but what seems like an eternity – puts trees and much else in the garden at risk from what will probably be a brute of a winter, if one believes the old adage that many berries signal a lean, mean […]
Have You Checked Your Soil pH Lately? You probably don’t think much about it, but the pH of your soil – its acidity or alkalinity – can matter greatly to how well your plants grow. And what many gardeners don’t realize is that they can be inadvertently altering soil pH every time they water their […]
How do you turn a stranger into a friend? You reach out and create a relationship, of course. And if those strangers are tropical plants? Marianne Willburn, author of the book, Tropical Plants and How to Love Them, has light-heartedly and cleverly introduced tropicals by categorizing these plants into five recognizable relationship stages—from summer flings […]
What does planning ahead for work in the autumn garden mean for you? Outdoors or in a conservatory does it amount to a quick tidy up? A bit of dead-heading, leaf-raking and winterizing the irrigation system? At the Clarke household, the Head Gardener (me) wracks her brain and wrecks her back to improvise and execute […]
This year my wood-framed greenhouse needed repairs after several big storms, including a hurricane, as well as 40 years of constant use. It leaked and required some serious attention. In fact, in one area the wood had rotted to such an extent that I could push a finger through it. This highlights the problems with […]
Stores full of beautifully mounded chrysanthemums is a sign that fall is arriving. If you buy some of these mums for a colorful fall display, you shouldn’t just toss them out when the flowers fade. Greenhouse owners can easily keep these plants going and also propagate more of them. Here’s how. First, you should know […]
Golden leaves are beginning to cloak the upper slopes of the Rockies, and with the aspens turning so turns the season. As the British poet, Philip Larkin, would have it, “Autumn has caught us in our summer wear.” Just like it’s caught generations of gardeners before us. Turning to my treasured 240-year-old edition of the […]
