When you’re transplanting in the greenhouse this fall, your soil mix will probably be peppered with small white granules. Yes, that’s perlite. But, after years of using it at my own potting bench, I realized I didn’t actually know what it is, or where it comes from, or whether its environmentally sustainable. For answers, I […]

Having decided on the power source you want to use to heat your greenhouse (see my Greenhouse Heating, Part 1 article), you still have another major decision to make: What heating unit are you going to buy? The options are often numerous and not easy to narrow down. Here are some factors to consider as […]

It’s been an exceptional season for peaches; my battered old tree produced its juiciest crop of fat, red ‘Elberta’ peaches ever—at least the ones that survived the squirrels. Daily combat with these rogue rodents reminded me of the fruit trees I’d seen grown in conservatories in England, often as espaliers against a warm wall. Protected […]

There’s an Instagram-fueled boom in houseplants today, which means I’ve come back into fashion for a while. This tends to happen to me every few decades if I just keep doing what I’ve always done. I come from gardening people, who tend also to be houseplant people. Even in the middle of winter, we’ve always […]

Exciting new plant introductions come on the market every year. And yet, how do we, as home gardeners, know what’s real and what’s fakery, put up by fraudsters who will prey on our desire to grow the latest offering? Wouldn’t that purple-leaf tropical vine look great in the greenhouse? How about a pink-flowering weeping willow? […]

Gardens are made of memory: of people, places, plants and all that nature offers us in such bounty that we do our best to hold it close in our personal spaces. This September, as I look out on my start-up prairie, formerly known as the front lawn, I remember a person who had more impact […]

In New England, heating a greenhouse in winter makes the difference between being able to grow citrus trees or tropical herbs and flowers versus growing only plants that can tolerate cold and even an occasional freeze. For many greenhouse owners in northern climates, growing the tropical and semi-tropical options is just too tempting. This means […]

The other day I almost picked a quince. It was an incidental quince:  The Japanese flowering quince shrub it was growing on had been planted for stunning coral-and-white spring flowers, not for fruit. However, the plant hadn’t gotten that memo and had developed half a dozen substantial, apple-like fruits anyway. Unfortunately, the shrub wasn’t mine, […]

At this back-to-school season, it’s time to study—what gets an A in your garden and greenhouse, and what rates an F? Take notes on both the perfect and the problem areas. Then you can hunt for plants that fit into these two categories. If, say, your foxgloves were a glory, find more for next year. […]

We all know that people who live in glasshouses shouldn’t throw stones. Well, I have a new twist on that old proverb: People who have glass greenhouses shouldn’t use a string trimmer nearby. An unfortunate incident taught me this lesson. Last spring, I decided not to weed between the slate stones of the patio that […]

It’s been said that if you have a view you don’t need a garden. Tell that to my plantaholic friend, she who inhabits a houseplant jungle on the top floor of a loft building with views of Pike’s Peak—if you can see it through the foliage. Of course, the walls are mostly windows, making the […]

The other day I strolled along a path between plants as tall as my shoulders, like a sea of green grasses with colorful swells of yellow coneflowers and black-eyed Susans, white ironweed and Indian plaintain, purple milkweed, and orange butterfly weed. Butterflies twinkled–monarchs, painted ladies, swallowtails—and bumblebees plodded from flower to flower. On the marsh […]
