Impossible Plants—How to Not be Suckered

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? […]

Greenhouse Heating. Part 1: Power Source Choices

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 […]

Fruits in the garden and greenhouse

The other day I almost picked a quince.

Cold Hardy Cactus: Opuntia with punch!

Part of the delight in growing hardy cactus, for me anyway, comes in not having to move pot-grown specimens into the conservatory as the temperature drops. The hardy sorts of opuntia (aka prickly pear cactus) are especially attractive and common throughout the intermountain and prairie regions of the West. Opuntia aurea, hardy from Zone 5-10, […]

Historic Gardens—What the past tells us about today—and tomorrow

I love the feeling of time travel that comes with visiting restored gardens. One of my favorites is Aspet—a garden designed around the home of artist and sculptor, Augustus Saint-Gaudens (1848-1907). The 30-acre garden and 200-acre grounds are now a National Historical Park in New Hampshire. When I visit gardens like this, one question always […]

Plants Need Secondary Macronutrients Too

You fill a watering can with dissolved fertilizer and start feeding your greenhouse plants. But do you know exactly what’s in the solution you’re using? Most greenhouse owners know that plants require nitrogen (N), phosphorus (P), and potassium (K). These are the primary macronutrients, the word “macro” referring to nutrients needed in relatively large amounts. […]
