Low Growers with High Expectations

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. […]

Jellyfish in the Glasshouse — Great Ideas from the Northwest Flower & Garden Festival

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 […]

Forces of Nature in Garden Design

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 […]

Two greenhouse grown artichokes ready to be cut and eaten. The plants will often put out smaller heads after the main head has been cut
Written in United States

Growing Artichokes in New England

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 […]

Weather is Coming—Will We Be Prepared?

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 […]

Why Do Plants Look Good in the Store and Then Do Badly at Home?

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 […]

Christmas Trees Wanted: dead or alive?

 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. […]

Asparagus 2
Written in United States

Starting Asparagus in Your Greenhouse

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 […]

Glass artist Barbara Sanderson relies on powder coating for long-lasting supports. (B. Sanderson)

In Praise of Powder Coating

Of course, any Hartley Botanic structure is colored using the powder coating process. That happens at the factory. But I never thought about using it for small items.  If you have rusted tables, chairs, containers, or shelving that you’ve never have gotten around to refurbishing with a coat of spray paint, consider powder coating instead.
