Is ‘no dig’ gardening really possible?

With a bow rake or an oscillating hoe in hand, he kicks off the new season with a quick pass over each bed, “tickling the soil surface,” he said, rather than upending it, “to disturb any weeds seeds that might be germinating.”

No tilling, thanks — or “no dig,” as he calls this method he has popularized.

It isn’t the only subject on which Dowding, a longtime market gardener in Somerset, in South West England, and a no-dig practitioner for 40 years, departs from conventional wisdom.

He doesn’t sow cover crops. (His beds are too busy with repeat plantings, one after another.) And he doesn’t rotate crops in the traditional manner, which calls for not growing the same thing in the same spot in consecutive years. (Last year marked his eighth year of successfully growing potatoes in one bed, and cabbages and fava beans in others.)

With certain vegetables, including beets, turnips and onions, he defies the usual advice about spacing. Instead, he “multisows” small groupings of seeds together in cells in his greenhouse and later transplants the little clusters into the garden.

And his at-the-ready hand tool? No, not pruning shears — a pocketknife.

But from one-third of an acre of active growing beds on his property, known as Homeacres, he harvests 25,000 British pounds’ worth of organic edibles annually, selling to a local restaurant and shops. Another yield: More than a dozen books, online and in-person courses, a YouTube channel with more than 600,000 subscribers and an Instagram account with nearly 400,000 followers.

People really dig no dig. (Sorry, that sentence was irresistible.)

Dowding finds an arrogance in humankind’s insistence that we must intervene to improve soil. In plant communities, from forests to meadows, he points out, leaves and other plant parts wither, drop and decay to support the soil without any churning.

Tilling doesn’t build soil structure, he contends; tilling destroys it. He advises that we follow nature’s example, “just leaving the soil alone as much as possible and feeding the surface with compost, so that the soil life does the work for us.”

And maybe the best part: It’s an incredible labor saver. (Although Dowding is no slacker.)

In his recent book “No Dig: Nurture Your Soil to Grow Better Vegetables With Low Effort,” he puts it this way: “Simple is best, and taking easier approaches that work well is clever rather than lazy.”

Clever gardeners — and those ready for fewer weeds, another major benefit of his approach — may find a match in no dig.

Bed Preparation, No-Dig Style

There is nothing tricky about this system, which hinges on a regular late-fall practice of mulching with well-aged compost. A deeper layer is applied in the beginning, followed by about an inch-deep application every year thereafter (and that “tickling,” as spring approaches).

Transforming an existing bed or another largely weed-free area to no dig typically requires nothing more than raking the surface level and spreading a 2-inch layer of compost.

To turn a piece of lawn into a bed, first mow it and then spread overlapping sheets of brown cardboard. Moisten the cardboard and top the surface with about 3 inches of compost.

Where the soil is poor or the weed pressure higher, go a little deeper, spreading 6 inches of compost on top of the cardboard.

To support that depth of material the first season — and to keep the compost depth intact, even at the edges where weeds will try to creep in — Dowding recommends framing the bed temporarily with lengths of lumber held in place by heavy stones.

“You could make a bed like that in the morning and put your plants in that afternoon,” he said. “You haven’t got to wait for the weeds underneath to die because your new plants, or seeds, start growing in the surface compost.”

By the time they’re rooting deeper, the cardboard will be decomposing, along with the lawn or weeds underneath. “And the soil will be opening up for receiving the roots of your new plants,” he said.

The usual objection he hears is that people don’t have enough compost for that initial application. Buying a load of well-aged compost is your best investment, he suggested, adding this reminder: The no-dig gardener will be buying no other amendments — and that means no more fertilizers.

‘Exhausting the Weeds’ and Multisowing

When Dowding sees a weed popping up, he doesn’t get in there with a big implement to try to unearth what he calls “the parent root.” He focuses on “exhausting the weeds” by taking off the photosynthetic part, over and again, “using a trowel, but doing it in a gentle way, going down pretty vertically near to the new shoot and levering out as much stem as comes out.”

Yes, it may take six months to deter an insistent dandelion, but the soil is not damaged or opened up substantially, which would give weeds an easier passageway upward.

Ever had large seeds such as peas stolen by mice or chipmunks from direct-sown rows outside? To defy them and to get a head start on the season, Dowding sows indoors in cells about 1 inch across, several seeds per cell, and then transplants each just-rooted cluster two to three weeks later.

He calls it multisowing, and he does it with beets, too — and radishes, turnips, scallions, onions, leeks, spinach and many salad plants, if he plans to harvest smaller leaves rather than whole heads.

“I transplant small, the idea being that there’s less transplant shock,” he said. “And it’s not actually much longer or harder work than sowing direct.”

So that the next generations aren’t so slow on the uptake, the latest project from this ultra productive vegetable grower is a no-dig book for children. Get them out there early and growing, he figures, like those young peas.
