One of the most effective ways to generate a multitude of plants is to grow your own from cuttings that will get a good start in the greenhouse. This month, I’m talking with Nancy Connolly Blum, a professional landscape gardener and former owner of the Sawmill Ballroom Lavender Farm in Oregon. Here are the propagation […]

Now that it’s spring in New England, it’s time for planting in the garden the vegetables and flowers that I started weeks ago in the greenhouse. But to do this, I have a special concern. Compared with inland temperatures, my garden in spring is significantly cooler due to winds that blow directly across the still […]

Three days from now it’ll be Earth Day 2024, and thoughts turn to the climate, which of late can be described–at best–as uneven; right now, snow is forecast for tomorrow, but on Earth Day, the sun will shine, and the snow will water the garden as it melts. My one lonely daffodil will be pleased. […]

Ideally, plants in gardens and greenhouses are designed in layers. And the most neglected layer is right at the bottom—the groundcovers. Using living plant material instead of just mulch makes for easier maintenance, and less weeding. This is true in garden beds and in containers, where shallow-rooted groundcovers do not compete with their deeper-rooted companions. […]

In the last nor’easter gale here in Rhode Island, wind gusts reached 60 to 70 mph. Usually, the greenhouse, which is in the lee of my studio, is not affected by northerly winds. But one sunny day this spring I opened the greenhouse windows to lower the interior temperature, which had reached 90°F (32° C). […]

I’m always a fan of the display gardens at Seattle’s Northwest Flower and Garden Festival because they offer inspiration for creative ideas to take home and try. This year “Dreamscapes by the Sea” featured a Hartley Victorian glasshouse with double porticos that allowed showgoers to walk right through. It was nestled into a lush garden […]

Sowing seed is the triumph of hope over experience, especially when seasonal conditions are wildly variable: Getting started takes a knock on the head as spring’s promise turns back to dour winter on a random schedule. Yet, growlights, warming pads, warm sweaters and other scientific advances aimed at greenhouse growing encourages us to get on […]

Here in coastal Rhode Island, I live in the US Department of Agriculture’s Plant Hardiness Zone 7a. This zone has a medium-length growing season and winter temperatures that, at their coldest, can drop to between 0° and 5°F. This makes growing artichokes outdoors difficult. These plants prefer a more temperate climate because most set buds […]

I was all set to write about the latest Hartley greenhouse that will be gracing Seattle’s Northwest Flower & Garden Festival—next month I will bring you that—but now, life (and the weather) has interfered with my plans. So many parts of the country have been devastated by unprecedented winter storms. Where I live, just outside […]

When you go to a garden center, the plants look wonderfully healthy and vigorous, so you buy lots of them. But upon taking them home and planting them in your greenhouse or garden, they may gradually begin to fade. First their growth may slow; then they may stop flowering; and finally they may start to […]

 The holiday season is upon us and in the Clarke residence it shows its face with the resurrection and plugging in of the Psychedelic Christmas Tree. As a couple of old groovers, this totem has particular significance, marking our first Christmas in Iowa in a rental and not knowing a soul in the state. […]
