African Violets: America’s Favorite Houseplant

One of the attractions that’s fed the “influencer’s” fiendish passion for promoting houseplants is probably that, in general, it’s hard to kill one – a houseplant that is. Anywhere that you are comfortable, be it conservatory, greenhouse or light-filled room, so will be whatever pet plant(s) you nurture. Three years ago, I acquired a rubber-tree […]

Greenhouse Heating Part 3: Keeping heat inside

Heating a greenhouse can be expensive over a long, cold winter, and not just at night. Winter sunshine doesn’t provide a huge amount of heat, and the cold air outside lowers greenhouse temperatures even more.

Daily combat with these rogue rodents reminded me of the fruit trees I’d seen grown in conservatories in England, often as espaliers against a warm wall. Protected […]

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. It was an incidental quince:  The Japanese flowering quince shrub it was growing on had been planted for stunning coral-and-white spring flowers, not for fruit. However, the plant hadn’t gotten that memo and had developed half a dozen substantial, apple-like fruits anyway. Unfortunately, the shrub wasn’t mine, […]
