FOR NEARLY 30 YEARS I’ve grown my greens in raised beds, however the sort that you might want to buy lumber and bolts and use a noticed and hammer to assemble, then fill solely with soil and compost. Currently I’ve been trying longingly at images of a centuries-old, sustainable approach of creating raised backyard beds referred to as hugelkultur, or hill tradition.
“It’s like sheet mulching or lasagna gardening,” says Dave Whitinger of the Nationwide Gardening Affiliation, who often lectures on the topic, however in hugelkultur, “wooden is the primary stage of your sheet-mulched mattress.” That’s his sturdy hugelkultur onion mattress up prime.

my hugelkultur q&a with dave whitinger
FOR DAVE (above), the thought of this model of recycling got here from a stroll within the forest—from the remark about how spongy and alive the bottom is from all of the years of fallen wooden and leaves, and his desirous to emulate that. With some analysis, he and his spouse discovered that it wasn’t a brand new thought, and that hill or mound beds with a woody base layer had been round for tons of of years.
A Texas accent however (Dave gardens and farms in East Texas, in Zone 8B), he tells me that hugelkultur is pronounced “HOO-gul-culture.” It’s a permaculture-style observe that makes use of woody particles together with branches, twigs, and even logs as a useful resource, relatively than burning them or eradicating them.
By capitalizing on woody particles, Dave says, you’re not importing and never exporting issues, both–in different phrases, performing sustainably. “For those who burn wooden, you’re actually exporting carbon into the ambiance.”
methods to construct a hugelkultur mattress
Beginning a hugelkultur mattress Dave’s approach does look loads just like the preparation of an enormous bonfire, nevertheless, at the least at first. The fundamental steps:
- Accumulate wooden (above, Dave’s large hugelkultur mattress at first; you can begin a lot smaller). The wooden might be chips, branches, even entire logs or outdated firewood that’s getting punky (the underside layer of an outdated woodpile, for example). Ask your energy firm to drop a load for you in case you don’t have a provide, however use what you will have first.
- Which woods? Softwoods like birch and alder, apple, cottonwood and poplar, and willow are sometimes talked about as extremely fascinating for the rising space/base of the hugel mattress, as are maple and oak. Black walnut, which comprises pure chemical compounds that forestall plant progress, just isn’t advisable. Some sources advise in opposition to naturally rot-resistant cedar, black cherry and black locust, particularly when freshly reduce, and notably within the rising space of the mattress (in contrast to make use of as aspect “partitions” in above-ground hugel beds). Opinions about the usage of conifers additionally fluctuate; some sources say to let the wooden age first earlier than utilizing within the rising space.
- Website the bed-to-be in solar in case you’re rising greens, however a shade backyard might be grown hugelkultur-style, too, in case you like.
- Mow the grass down on the world to be gardened. Then smother what’s there with cardboard, like this. Don’t until.
- Pile up your wooden. Make any form that you really want, maybe a keyhole-shaped mattress, or put a number of of these collectively, as Dave did, and you’ve got “a mandala-shaped backyard which you could stroll inside.” His is 30 ft extensive, “filled with pathways all via it.”
- You possibly can put borders reminiscent of stones, logs or 2-by-8-inch boards to outline the mattress, although Dave doesn’t trouble with edging.
- Talking of which: For those who’re making a standard raised mattress like mine, put wooden in first earlier than filling with soil and compost and so forth. Use woody particles as a base layer inside your containers.
- Cowl your woody base with compost, a bit of soil, straw, outdated manure, spoiled hay, grass clippings–no matter natural materials you will have, to a depth of about 12 inches on prime of the wooden. In case you have Nitrogen-rich materials reminiscent of recent grass clippings, put them proper close to the wooden to assist it get began breaking down.
- Inside just a few days the mattress will begin to cool down–however Dave prefers to prep new hugelkultur beds in fall, nicely earlier than spring planting. “I like them to spend the entire winter stress-free,” he says, “and get colonized by microbes and so forth.”
- Bear in mind that you’ll be low on N at first–however, “the mattress will give all of it again in time,” says Dave. Newish beds do nicely with potatoes, for example, which don’t crave plenty of Nitrogen—however don’t attempt to plant your corn (a really heavy N feeder) on a brand new hugelkultur mattress.
- Aftercare in subsequent years: Because the wooden breaks down, it’ll begin to collapse considerably. “We add compost to the mattress at any time when we’re planting,” says Dave, filling in planting pockets as wanted at the moment.
- Dave Whitinger’s slideshow and extra detailed hugelkultur how-to offers additional inspiration.
what grows nicely in a hugelkultur mattress?
OkEEPING THE “biomass” of all that wooden proper on web site does greater than make a fantastic raised mattress. It additionally offers the little creatures—fungi, mycorrhizae, bacterium, bugs and extra—the meals they crave, and a really perfect setting to thrive in.
Vegetation grown in a hugelkultur mattress thrive, too—Dave’s hugelkultur-bed onions, for example (prime photograph), are way more vigorous than these grown conventionally, and he has had glorious outcomes with herbs, potatoes, candy potatoes, gourds, peppers and way more. Not simply gourds but additionally different cucurbits–pumpkins and squash–likewise do nicely.
“I can’t consider something that doesn’t do nicely in a hugelkultur mattress,” he says.
The ensuing crops are “miles forward of people who find themselves rising it with a area of triple-13 fertilizer,” he says, referring to store-bought generic artificial bagged 13-13-13. Certainly.
