Window Cleaning and Maintenance

When summer arrives in Rhode Island, I move everything out of my greenhouse in preparation for a cleaning blitz, including window cleaning. It’s easy to clean the outside of the windows year-round because no plants are in the way. But when the greenhouse is full, cleaning the inside of the windows is difficult because access […]

What Garden Tools Are Best in a Greenhouse?

One of the first things you learn when working in a greenhouse is that long-handled tools can be a problem in such an enclosed space. While the tool’s working end is where you want it, the other end may knock pots off shelves, damage plants, or even break window panes. The only long-handled tool I […]

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 […]

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 […]

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 […]
