Commercial Grower Prefers Cuttings for New Plants

Commercial grower prefers cuttings for new plants

Recently I visited Pleasant View Gardens in Loudon, New Hampshire, a major grower for the plant brand known as Proven Winners.

What amazed me is each year from December to March the amount of small plants, called liners, that Pleasant View grows from vegetative cuttings.

The liners or small plants are then shipped out to garden centers that repot them and grow them til the spring for sale at the nursery.

Rochester, New York seed company owner James Vick (1818-1882) advised the use of cuttings for new plants in his magazine Vick’s Illustrated Monthly.

Vick proposed the use of a bell glass for small pots, each holding a number of cuttings. [below]

The glass jar of course controlled light, moisture and temperature for the young plants as they grew.

Pleasant View devotes 700,000 square feet to the many trays of plants in special greenhouses which afford ample control of heat, light, and moisure.

In this way Pleasant View grows millions of young plants to ship out in the spring to garden centers and nurseries, mostly on the east coast.

Here is a photo I took of trays of cells, each of which contains a small plant. Notice how many plants there are in just this small space in one greenhouse. [below]

Small plants in cells, inside a tray, await shipment to a garden center near you.

Vick understood the science of this process of growing plants through vegetative cuttings.

In 1879 he wrote, “The florist and the nurseryman construct propagating houses, with beds heated by pipes with hot water flowing through them, to keep up a steady heat to encourage the production of roots in advance of the growth of the stem.”

Vick knew the importance of vegetative cuttings to reproduce certain plants like many annuals.

Today, Pleasant View does ninety percent of its propagation for Proven Winners with vegetative cuttings which, in this case, are flown in from Central America.

Darwin Wrote about Plant Struggle for Survival

Darwin wrote about plant struggle for survival

This past June here in the NE provided a great deal of rain. It kept pouring down for what seemed days and days. Little sun appeared.

What grew in the garden, without bounds it seems, were weeds.

I have never seen such a vast number of weeds which took over so much of my garden. I spent what seemed several weeks just weeding.

Dealing with weeds is an important way to understand not only gardening but ecology as well.

In the book Darwin’s Backyard: How Small Experiments Led to a Big Theory the author James T. Costa writes about Darwin’s many experiments with plants.

Weeds like all plants are trying to survive. We humans call these plants ‘weeds’ which legitimizes and encourages treating them like an enemy that must be crushed.

Costa writes, “What seems an exuberance of vegetation with its flitting and creepy-crawly denizens, unruly enough to strike terror into the heart of gardeners whose taste favor the manicured has in fact a certain order or underlying structure in Darwin’s eyes.”

This ‘struggle for existence’ that Darwin explored in his work could well be the story of the weed.

Costa writes, “When we observe nature we often miss the struggle, seeing only peace and harmony, and mistake this for the natural condition of the living world.”

Perhaps that is a lesson that gardeners learn only too quickly. The peace and harmony we search for in the garden is really a state we impose on the garden.

The garden is a place where plants struggle to survive. Some make it while others do not.
