One of the biggest trends in indoor gardening nowadays is hydroponics—growing plants indoors, usually under lights, with their roots in water that is enriched with fertilizer. This technique (fine-tuned in the last decades of the 20th century for the discreet production of marijuana) is now developing into a small but significant sector of agriculture. If […]

Mandevilla is a genus of flowering vines with showy, trumpet-shaped blossoms in various vibrant colors, making them highly popular for patios and decks.  In cold climates, however, they must be brought indoors for winter. Fortunately, a greenhouse is an ideal winter haven for Mandevillas as long as the temperature there stays above 50˚F. Before bringing […]

Glasshouse and conservatory construction have come a long way since the days of ancient Rome, when Pliny the Elder wrote about the Emperor Tiberius’s love of cucumbers. Such was the regal passion for the vegetable that he had, as Pliny described, “raised beds made in frames upon wheels, by means of which the cucumbers were […]

Pomegranate, Punica granatum, is a small tree native to the Mediterranean reaches of the near east, and so in zones where the temperature drops below 40F, is a pretty and productive addition to a conservatory garden.

The much publicized health benefits of turmeric, including anti-inflammatory and antioxidant properties, have made it a popular addition to everything from lattes to smoothies to teas. Although fresh turmeric tubers have been said to have more potent health benefits than the powdered turmeric sold in grocery stores, a small bag of them can cost upwards […]

It’s very tempting to have an empty greenhouse during winter, but there are things you can grow. For many years now I’ve been taking the tomatoes out of one greenhouse, having a quick tidy up and popping winter salads in. It all began when I read that bagged salads might have been washed in diluted […]

The aspen trees have moved from shining beacons on the mountainsides to puddles of gold beneath the trees; greenhouses — retail and residential — are being cleaned out, and pumpkins, turkeys and sugar plum fairies are dancing in shoppers’ heads. The holiday season is upon us. In 1574, Nicolas Monardes, a Spanish man of letters, […]

Cape Primrose, or Streptocarpus, is a genus of beautiful flowering plants that contains numerous species, most of which are easily grown in a heated greenhouse. These plants superficially resemble those of the genus Primula but are not related to them. In many ways, the five-petalled Cape Primrose flowers remind me of orchids. Each has somewhat […]

I don’t believe I’d ever seen as many big leaves outside of a conservatory as I did in Buffalo, New York, last summer. In the small residential gardens I was touring, elephant ears in pots were everywhere, doing their best to bring a tropical air to the place. I could easily understand why a hint […]
