In northern parts of America greenhouse owners are just now starting tomato plants from seed ready for the new season. Under lights on the heat mat I have some fifteen varieties growing. These will be transplanted into larger pots until they are ready for my garden and the gardens of friends. But often tomato varieties […]
The semi-arid steppes of the world can teach us ways to conserve water in our gardens and create sustainable landscapes. This year the North American Rock Garden Society, aka NARGS, is holding its annual general meeting in Colorado, hosted by the Rocky Mountain Chapter. Kicking off at the Denver Botanic Garden, it then moves to […]
If you are a greenhouse owner in the northeast you should treat yourself – take a trip to the Philadelphia Flower show. What makes it spectacular? The show is held in early to mid-March when there is very little in bloom outside of the greenhouse. Many of the prizewinning plants are grown by enthusiastic greenhouse […]
When sleet is still rattling against the glass of the greenhouse, it’s hard to get your head into spring. But if you think ahead in March, you can take advantage of a glasshouse to get a head start on the summer garden by potting up tender bulbs. These are plants such as agapanthus, with its […]
“A room of one’s own… What [these words] propose to anyone who admits them into the space of a daydream, is a place of solitude a few steps off the beaten track of everyday life.” So wrote Michael Pollen in A Place of My Own. And he wasn’t talking about greenhouses. But he could have […]
Deer tracks in the snow show where a hungry buck gazed wistfully through the glass at the tasty-looking green plants inside your greenhouse. Squirrel and rabbit tracks betray the presence of other wistful watchers that would envoy your greenery even more than you.

Even if you have a greenhouse, you’ll need a light setup to give most plants […]
Jump-starting vegetables in your greenhouse celebrates the beginning of the year’s growing cycle. But potatoes? I hadn’t considered them as greenhouse candidates until I read the new 35th anniversary edition of my go-to edible book, Growing Vegetables West of the Cascades by Steve Solomon and co-authored this year by Marina McShane. Now why would I […]
If you’ve ever brought geraniums or pelargoniums into your greenhouse at the end of summer, you probably know how leggy the plants become in winter’s low light levels. Come spring, you can cut back these plants significantly to get them started anew, but the initial result is an ugly brown stem visible in your hanging […]
Winter is the time when many greenhouse owners are thinking about starting seeds. They may be reading through catalogs, cleaning pots, checking their supply of potting soil, and perhaps placing orders. But one thing that is often overlooked is a heating mat to go under your seed flats. With the gentle bottom heat that a […]
Now that all that holiday fuss is over, it’s time to get down to serious business: gardening. In the middle of winter? Well, sure, if you have a conservatory. You can be as busy as June, patrolling for insects and diseases, monitoring temperature, humidity and air circulation, and preening and primping your plants. But even […]
