Grow Your Own Avocados and Mangos

Avocados and mangos are both very popular fruits, not just for their delicious flavors and versatility, but also for their significant health benefits. Both are loaded with vitamins and powerful antioxidants, in addition to many other nutrient properties. These characteristics are among the reasons why health-conscious people are increasingly adding them to theirdiets. Most of […]

Growing Organic Fruits and Vegetables Year-Round

Have you noticed that produce has become more expensive in supermarkets lately? One reason is the cost of transporting fruits and vegetables from the southern hemisphere, another is unfavorable recent weather in California, a major supplier of produce, and a third is a decreased number of migrant workers available for harvests. If you’re a greenhouse […]

Highlights of the Philadelphia Flower Show

The weather forecast was foreboding, with the third major winter storm in two weeks about to hit the northeast. But the blinding snow and lashing winds that my Amtrak train hurtled through on its way to Philadelphia belied the beautiful, springtime ambiance awaiting me inside the 2018 Philadelphia Flower Show. This premier horticultural event, presented […]

Heritage Gardens in Sandwich, MA

This spring I visited Heritage Gardens in Sandwich, Massachusetts, to see the rhododendrons in bloom. These 100 acres were formerly the estate of Charles Dexter, who, beginning in 1921, spent years propagating and raising thousands of rhododendrons.  He gave many to friends and neighbors without keeping records of these gifts, which is why new Dexter […]

Mandevilla Care

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 […]

Grow Your Own Turmeric

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 […]

Growing Cape Primrose

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 […]

Make Your Own Hanging Baskets

As a greenhouse owner, you can easily make your own hanging baskets rather than buying them at a nursery. If you start your basket plantings in late winter, they’ll be large, lush, and ready to put outdoors after Jack Frost has quit for the season. I prefer very large, 20”-diameter, peat-lined containers for my hanging […]

Add Hydroponics to Your Greenhouse

For a number of years, I’ve grown lettuce in plastic gutters in my greenhouse. The installation is simple: Each ten-foot-long gutter hangs from brackets on a greenhouse wall, with one end four inches lower than the other. I fill the gutters with clay pellets to give the plant roots something to grip. A fish-tank pump […]

Michele Keith’s Greenhouse – in Chilly Wyoming

I talked with Michele Keith about her greenhouse in Wyoming. Michele’s property, which is close to the eastern edge of Yellowstone, is 6,000 feet above sea level and in hardiness zone 4, so it gets very cold in winter. She had 36” of snowfall a week or so before our talk. But cold is not […]

Growing Bananas in a Greenhouse

Bananas are native to Southeast Asia, so growing them in northern climates is a challenge. When I first tried growing bananas in my Rhode Island greenhouse, I kept the greenhouse warm all winter, knowing that bananas prefer temperatures over 77o F (26oC) year round. After three or four seasons and a lot of money spent […]
