About twenty-five years ago I bought some asparagus roots, planted them and waited to enjoy the stalks. The bed has provided fresh asparagus since that time. Every year, I add more seaweed and well-rotted horse manure or compost to the bed and have been rewarded every spring with fresh asparagus. But now I find that […]
Although most plants convert light energy to chemical energy by photosynthesis, not all obtain the nutrients they need through their roots. Many of those that don’t live in bogs where their roots are permanently in low-nutrient, poorly-drained soil. One adaptation in this environment is obtaining nutrients, especially nitrogen, by digesting insects that visit the plants. […]
How much do you enjoy biting into a luscious, rich red strawberry? If the answer is greatly, you may want to grow your own strawberries in your greenhouse. Doing so isn’t difficult, and the results can be delectable. To get started, you need to decide what type of strawberry you want to grow. There are […]
It’s late August, and it’s hot, but my unheated greenhouse needs to be readied for winter vegetables. I’ve developed a method for getting this job done, one that not only adds nutrients to the soil but that also adds a natural heat source. Here’s what that method entails. I start by digging out the greenhouse’s […]
In summertime, it’s hot and dry in much of America for extended periods of time, but plants still need water – typically lots of it. What’s more, keeping greenhouse plants watered in these extreme conditions is made even harder when local communities impose lawn and garden watering bans to conserve their rapidly depleting water resources […]
In the dog days of summer, entering the greenhouse is like entering a sauna. Working there, even with the door and windows open, is a form of masochism that even I balk at. But work in it I must. Although my 200+ plants have been moved outdoors, there are still summertime maintenance tasks to do […]
Dahlias have become a very popular flower to grow in home gardens, but in New England the season for them is normally quite short. It’s best to plant dahlia tubers outdoors when the ground temperature is above 55oF (12oC), which for me in Rhode Island means not until late May or early June. So if […]
In the summer, and often in spring and fall too, I leave my greenhouse door open to keep the interior from overheating. If I were to keep the door closed on a sunny, mid-summer day, the temperature could easily soar to well over 100o F (38oC), wilting virtually everything inside. But leaving the door open […]
Owning a greenhouse allows you to get an early start to growing your own flowering plants for hanging baskets and patio pots that can be set outdoors in summer. Among your choices are begonias. They come in a wide range of colors, thrive in warm weather, don’t require a great deal of water, have a […]
What can be better than going out to your garden, picking a few sun-warmed tomatoes and enjoying them for lunch or dinner? Tomatoes are the most popular garden plant grown in America, but do you know your determinate from your indeterminate? Your heirloom from your hybrid? Or why some tomatoes have VF, A, FF, or […]
A while ago a gardener asked me what my greenhouse’s greatest insect problem was. I answered whitefly, which is a terrible nuisance that can easily get out of control. That conversation got me thinking about the Sisyphean task of trying to eliminate my whitefly infestation by spraying infected plants with Safer’s Insecticidal Soap. The more […]
Have you ever heard about straw-bale gardening and wondered what it entails? The answer is more than just stacking straw bales to make windbreaks or taking them apart and using the straw for mulch. Straw bales are far more versatile. They can be used as a base for growing plants in a greenhouse. But when […]
