Is this statement still true today?  If so, I'd like to find out more.  

Our Forest Service is hell bent on burning slash piles, and here in the Southwest USA between the on-purpose burning and the wildfires there is hardly a day that goes by from early spring through early winter when the air isn't smoky.  I'd like to put forth a proposal to the USFS for a test site where volunteers use hugelkultur for the piles to show that hugelkultur is better for the soil and eventually the flora and fauna, for air quality, and ultimately the whole planet, than burning slash piles.

Any resources that could provide hard data on anything at all supporting a hugelkultur treatment of slash piles on public land would be appreciated!

I have never heard of this before, but am quite fascinated with it.  I have many times over the years gathered up my brush and laid it on the ground and then covered it over with some soil and then planted potatoes and whatnot in it just as a means of dealing with the brush.

I have forty acres with about 20 acres of timber, I have an impressive amount of old rotting wood and create more all the time with wood milling.  I am pretty certain that I could round up with enough time and effort probably 40 or 50 tons of material laying around my place.  Plenty of material to work with.

My garden is situated below the dam of one of my ponds and has about 6,000 gallons of water draining through there everyday, I originally built that for hogs and then eventually made it a garden.  I figured the running water seemed to melt the snow off earlier and that I could use that to my advantage.  It took a few years to get enough plumbing in the garden and build the garden up high enough to deal with the excess water running off, but as of this year I have my entire garden worked by the first week of March as the snow melted off quickly.

Just today I was looking out the lower side of my garden thinking about how I could make use of the area there with all that water running through.  This might be an answer to that situation.  If I stacked wood in there in piles like this the water could run through and around while the planting area stays high and dry.  As for nitrogen, the snow melt water running through has nitrogen as well as the run off from my pond which is full of catfish.

Do you think this would work well in a wet runoff area?  Could a person maybe pound in stakes at the sides and pile up the branches and rotting logs vertically inside of the stakes and make kind of squared off planting boxes covered over with the soil?

I was looking for a new gardening project for week after next maybe this is my new project.  As luck would have it I have a 10 year old slash pile literally right next to where I want to do this and I have piles of topsoil out in my hay field from the building of the five ponds on my place 30 years ago, so no shortage of soil to work with.

Not only should you do it, but please share reports and photos with us!

I have been gathering soil from my southern forest the last few days to use in my gardening.  I have brought in about 10 yards of material into the garden so far this year.  

In the process of gathering soil I have been clearing branches on the trees up to a height of about 6 to 6 1/2 feet high.  From the last 7 1/2 yards of soil I have pulled out over the last 4 days I have generated probably 1 ton or more of branch piles to clear.  Whenever I do any work in my forests I try to clear branches and pile them up in neat piles.  I was thinking today about just how many of those piles I have stacked up over the last 8 years, must be a hundred truck load sized piles. Then I started thinking of all the branches I have yet to clear in the 12 acres or so of forest I haven't even worked in yet and I realized that I have an amount of junk wood that is almost beyond my ability to describe.  This hugelkulture idea would be quite the handy means of getting rid of all that garbage wood sitting around.

I walked down below my garden this afternoon with my son Ted and was describing to him my idea for this hugelkuture, the whole time we are standing on the dam to my sewer pond and I was looking at the ugly falling down barbed wire fence.  I realized that this might not only be a means of getting rid of a bunch of junk wood and not just a means of expanding my garden, but I could actually put in a circular hugekulture "fence" around my sewer pond.  I realized that this could actually be used for beautification/landscaping as well as the getting rid of the wood garbage and growing veggies.





So far I am thinking that I will start by cutting the large ends of the branches off and pounding them into the ground at about 12 inch spacing.  Then I will come back and weave branches through those with opposing weaves each layer.  Then I can drag in my branches and maybe halfway up go ahead and tie a jute cord from side to side every few feet to help hold the entire thing together and keep it from spreading apart at the top as I pack in branches.  Run the sides up to maybe 3 feet high and aim for about 3 feet wide and then lay in a few inches of pine needles then about 4 inches soil on the top and then mound it to maybe 8 to 10 inches in the center which would allow for the soil to drop into the wood a bit as it all rots down.

As I was standing in the yard after that I was looking over the pond next to the house and the 140 foot long dam and I realized I could something similar on the upper dam slopes as well.  I could do a small 3 foot wide hugelkuture system on either side of the dam and leave an 8 foot walking path in the middle.




I will have the main garden done and planted by the end of next week, at least done planted until May/June anyways when I will be able to plant my warmer weather plants anyways.  So on to some hugelkulture beginning of next week then.  I will just run around and collect some of the easily reachable piles of brush and what not for the first bit of work and clean up the junk laying around the work areas and the house to start with but as the summer comes on I will go ahead and start gatheriing all the junk wood from around the place and see just what we can in the way of cleanup/ hugelkulture/landscaping/gardening/tree farming/logging this year.   I have to keep my forest in decent shape for it to qualify as timber land which has a deferred tax here in Idaho.  I don't have to pay any taxes on the timberland until I harvest and sell the timber.  

I don't actually sell my timber as I own a sawmill, I just selectively log my forests and then mill lumber for my own use around here.  This leads to a great deal of garbage wood and firewood as I clean up the forests.  No one has ever cleaned these forests over the last 40 to 50 years so there ahs been a great build up of material over the years from dead and fallen trees, old stumps and loads and loads of branches.  I have been been half heartedly working at cleanup over the last 8 years but I haven't accomplished a whole heck of a lot of the cleanup as yet.

This hugelkulture idea could really make my overall forestry operation far more efficient.

I have been watching a number of videos on this and I have seen the complaint several times now on voids in wood not being easily filled up and this causes varying levels of collapse over time.

I gathered together about 80% of the branches and brush near my sewer pond yesterday and laid it all down into the space between the sewer pond dam and my garden fence.  It is full of open gaps and whatnot and would drop a great deal over time.  I could go in and cut the stuff up a bit and pack it in tighter, but that would be a fair bit of time and a great deal of effort.  

I was thinking maybe just filling all of those voids with wood chips.  My friend Geof owns a tree trimming business and bought 40 acres 3 miles down the road from me, he chips all of his smaller tree trimming and tree removal waste and dumps probably 50 to 100 loads a year at his place.  That should work just as well as brush and branch wood right?  I will see if I can get ahold of him and have him dump off a dump truck load of chips at my place to use for this purpose.

While I have to say the garden aspect of this cool, quite honestly the part that I am finding the best is how much easier this make my wood cleanup.  I spent an hour and half dragging that wood over and dumping down in there filling up that 6 feet of void space.  Ordinarily I would have had to load it all on the trailer in about two to three trailer loads and hauled it all over to my brush pile out behind the barn and shop and then unloaded it all.  I would have been a good four to five hours into that cleanup and still had an ever growing brush pile.  I will be able to pretty easily deal with large quantities of this brush in a much more efficient manner now.  Yall are far underrating the usefulness of this idea in the area of making cleanup easy.  I am seeing crazy cleanup potential with this.

Hello, so I've just recently come across the concept of hugelkultur and I love it. I happen to have a lot of woody debris on my property I've been wondering what best to do with it, and then it clicked!

Now, I've been reading that pine is a less desirable wood to use due to tannins. I'm wondering though, should I let that stop me? I have mostly White Pine branches and another species I haven't identified yet. Will the tannins significantly limit what will grow well? Should I focus on growing perennials that grow well near pines?

I am in NE Ohio, zone 6.

Hello Daniel and welcome to permies! Great to have you here!

As far as pine and hugelkultur beds it can work fine. It really depends on a couple factors. You mentioned you have a lot of woody debris on your property--if that woody debris is already starting to rot then just go ahead and use it in a hugelkultur bed. It should work fine since the decomposition process is already well on its way.

But if the wood is more fresh and not starting to decompose then the question is this--how quickly do you want the hugelkultur bed to be in full production? Using fresh white pine wood will likely mean the hugelkultur bed won't be super productive for at least a few years. Though you can speed that process up by adding nitrogen rich material to the beds. Regardless I would make sure the wood is fully buried with soil well mixed in around the wood so the wood stays in full contact with soil. This will help keep the wood moist and speed up the decomposition.

Overtime the beds will settle so if you don't mind waiting a few years for full production then you don't have to be so careful to get the soil in all the cracks and spaces between the buried wood.

Observing what is already growing near the pine is a great way to pick some initial species--though any species that grow naturally under pines should do fine. I would include some nitrogen fixers too. I would also experiment--try some plants you think are safe bets but also add some that your less sure about. But just a few of those "risky" plants--some of them may surprise you and do great which will help you figure out what else to plant.

Good luck and again welcome to permies!

Thank you Daron for your welcoming and advice, I'm happy to have stumbled upon permies!

I'm also wondering the best positioning for a hugelkultur bed in my yard. I'm in a small city lot, about 140ft x 80ft. The house is situated far back from the street and the front yard has a slight downward grade toward the house, which is square on the west side of the property.
If I uploaded some pictures, would you be able guide me on positioning? I imagine there's a lot of flexibility, I'm just very new to gardening in general and I like to think things through before I do something, I'm very aware of my ignorance. I know where the water flows to, where my sun is coming from, I have a lot of shade. But I'm not sure what I should prioritize, a deeper mound for water retention? A larger one for wind block? Should I orient it perpendicular to the slope or along with it? I'm also considering multiple smaller mounds vs one big mound or maybe one long, shallow mound. It might be nice to redirect water flow around the house as well. So many factors to consider!

I called up mu buddy Geof who owns a tree trimming company and asked if he might have any wood chips in the near future that he might be able to drop by my place.  He mentioned he didn't have any but he could come by on a weekend with his chipper and dump truck and chip all my branches for me in trade for a weekend of myself and the boys going over to his place and helping him thin out the small trees in his 20 acre forest.

So now to get all the branches gathered here in rows to run through the chipper and arrange a time to get over and thin out his little forest...  Great trade out, this will chip all my current branches up and give me a few dump truck loads of wood chips to mix into the branches that I trim through out the spring and summer.  This should make for some great hugelkultur trials.

Now if it would just stop snowing....  I woke up to this yesterday morning and it is still snowing and apparently going to continue for much of the next ten days, but it is looking to warm up at then end of that on the 14 day forecast...  Finners crossed...

@Lif, your suggestion of using slash piles for hugelkultur is interesting and while there might be a few places where it would be applicable, I seriously doubt that the USFS would go for it as a general rule.  The problem is that as it breaks down it nutrifies the soil.  In some places you need that, and in many places those extra nutrients  can provide conditions which promote invasive weeds.  I once worked on a project where they used to push the slash to the edge of the site, and those areas were now totally hammered by invasives, while the center of the areas were nutrient starved and promoted a a lot of natives, a couple of which were rare and/or threatened and only grew in nutrient poor environments.  As a note, I worked with the USFS in New Mexico and Utah fighting fires, wetlands restoration, and ecological modelling.

And, not doing my due diligence in researching further I feel I have screwed up big time. ugh. Two years ago I I had two large oak trees felled. The one was 5ft in diameter. Chewed up a chain due to an old unknowing fence line straight through the center of it too. The larger split-able stuff was given to my dad for his fireplace.
The branches: some made it to the chipper, some a pile down below the bank from my house, and some into a pit three feet deep by 4ft wide by 12 feet long i dug in my garden as an experiment. Only I think I may have messed up. I keep seeing mounds now instead of pits. This year I got a mower with a bagger after i realized how much i can do with the grass and added some to the top of the pit to kill off the weeds that accumulated last year over the dirt filled pit. Thinking here was replenishing the nitrogen the wood sucked out of the dirt and stuff.
SO my question is this.....do you think i can still grow plants on top of this pit even though it isnt a mound, and  to mound over the grass what type of soil should i put on top to heap it up for growing?

Also on a side note: I know walnut trees have some sort of chemical that kills plants off. is the wood still good for beds or not?

Hi folks!

I've been spending days reading this thread (am about halfway through now and finally signed up) and I'm soaking up the knowledge!

I live in Belgium (the south-east of Flanders, the Dutch speaking part) near the Dutch border. Our soil is mainly sand. We are very lucky to have the use of a large (by Belgium standards anyway) plot of land (it's about 20 by 30 meters) that we are allowed to garden on. In fact, my in-laws gardened there for about 30+ years, and since the last 5 years or so, we've been taking over. I've been slowly learning about permaculture principles and try to incorporate more and more of them as we go along. Our summers have been unusually hot and dry for the last couple of years, and in my quest for a water retention solution, I found hugelkultur.

Now, our garden is owned by a neighbor and although he doesn't mind us being there, we are unable to make any structural changes that normal people would consider weird My in-laws gardened here rather traditionally (although pesticide free), and the soil is rather poor. We've been improving with mulch and compost but it's a slow process, especially since we're still learning along the way.

I've built three beds that could basically be called baby-hugels. They are about 1,5 to 2 meters long (so 4 to 6/7 feet I think?), 1 meter (3') wide and 2' high. I dug a trench about a foot deep before putting in the wood, so overall height would be 3'. I covered the wood with twigs and branches, cuttings from hedges, half-rotted compost and horse manure, then put the top soil back on (well, soil... the sand, that is), mixed with compost. I mulched with hemp and flax which is normally used for horses stalls. I didn't have anything else at hand and I didn't need much since the beds are quite tiny compared to what I see here. I planted zucchini, peppers and tomatoes on top, and nasturtium all over (because I love it and so do the bees, and it seemed like a nice cover crop). The last bed I made I plan to put some brussels sprouts on top, to compare them to the ones I planted in the regular beds (sprouts tend to be very small here).

I know my little beds might not last as long, but I don't think we'll be here in 5 years so I wanted to get some of the benefits and less of the work, and also less change to the landscape. I'm very excited to see what they will do!

And now I am going to finish reading this thread and dream about our future homestead in which we can put al this wisdom into practice!

Hallo

I am tyding up the land of my grandmother, that has been left for quite a while.

The moment i read about Hugelkultur, i just went for it, as i don't have soo much time, and it seemed perfect to get rid of some wood, and to stop some weeds from taking over the garden.
Planted salad, raddish, cale, spinach on it as i figured i woud still get something out of it this year.
Now that i'm done, i started reading more, and i read that saland  and spinat should be avoided in the first 2 years as they would absorb to much nitrogen?

Is this a real concern? Can i do something about it? Or should i remove all the seeds?

Any comments would be greatly appreachiated, i'm getting into permaculture, but also have still quite many other things to do

hi Simon - from my experience trying several different versions of this my thought would be that it depends on how much soil you added to the top, and what else you added besides the wood.  

what I've been doing at the end of each growing season is digging around the vegetables to see how far their roots went down, how far they spread across, and how thick they were.  plus, I wanted to check on what the soil looked like 3, 6, or 9 inches down.  from what I've seen if you are growing mostly those green leafy crops they don't seem to root down very far - although that probably depends a lot on soil makeup.  

my native soil is actually almost pure sand except for an inch or two at the top, so when I built my hugels they had to be in the form of filled pits instead of piled up mounds, but the idea is the same.  the rotting wood was topped with several inches of compost and fall leaves and yard clippings all mashed together, and then the sandy soil went in mixed with the topsoil I had set aside for the very top.  when I dug down at the end of the season I'd hit the mixed material at about 4 to 6 inches down, and surprisingly the roots of almost all the plants would go that far and then spread laterally.  it seems that the rotting wood and compost and all are doing such a great job of holding and wicking up water that the plants don't need to reach deeper.  and the heat from the decomposition has allowed kale to overwinter (this is a solid zone 4 with 3-4 foot frost level normally so my kale always died off) and melts the snows off weeks ahead of everywhere else in the spring.  

I've grown tons of greens, loads of bush beans and pole beans, chard, tomatoes, cucumbers, and squashes along with a mix of carrots, beets, and some others in the hugels.  all of it has done incredibly well, far outproducing the neighbors who are doing traditional gardens with tilling and fertilizers.  I think if you are worried about the nitrogen loss the first couple seasons you could add compost over the bed and be fine, as those shallow roots will take it up from there and do well.  I tend to do this any time I harvest a crop and am getting ready to sow another one - I just spread an inch of fresh compost over the whole area first.  I've learned that keeping something - anything - growing to cover the soil at all times is the best method, even if it's just some beans or peas that won't have enough time to produce a harvest, I use them as a cover crop and then chop and drop to protect the soil over the winter.  then I watch the neighbors clear off their gardens and leave them bare for the winter and wish I was better at pitching these new ideas to folks...

Potential tools for hugelkulture on a huge scale?  Starting 39 seconds into the video and going to 2 minutes.  If you could get it stirring a bit more dirt into the pile it might be amazing while tackling slash piles from forest logging.

ok, ive got a pretty good size pile of  wood and bark that ive been piling up but it got invaded with very invasive vines, not sure what they are, some of it might be honeysuckle,
any suggestions

I have created two hugelkulture beds  One disappeared into soil, the other hill (about 16 inches high now) is growing red clover.  I used free wood chips dropped off.

Plan on collecting leaves in a big column.  I have clay loam.

@Bruce,  I am not sure it would be the "hugelkultur" way or not, but check into solarizing the beds -- spreading cardboard, paper, plastic or a silage tarp, over the beds to kill the invasive vines and then plant with something that will enrich the soil like beans, clover, or another cover crop.  As a note, I have used silage tarps before (both black and white), but one of the instructors in my Master Gardner's class used simple butchers paper in the same way.  I have only really read about using cardboard to kill the old weeds, etc., and then spread a thin layeer of soil on top and plant in that.  The cardboard and/or paper will decompose and the plants will grow through it.  I have not looked at what all is in the papers and cardboard to be comfortable doing that at scale yet, but maybe it would work for you.  Also, some of the vines are very aggresive and you may need to kill off the runners trying to get away from the current mound.

Just a thought, best of luck.

Hey, thank you for this helpful post and ideas!
I have also soil that is almost sand.  Looking forward to spring!

Good luck!

Posted an utube link that just seemed to glorify NL tractor attachments.

After our big ice storm in Oregon's Willamette Valley, our little town created a gathering place for wood and the city and county worked to create huge piles of chipped wood, large 8' trunks of trees, and other types of debris. It wasn't just huge. It covered an entire block and the bark "mulch" was in 7 or 8 30' piles 15' high! I took my little pick up and pitchfork and started filling up. Four loads later, my yard is covered and I went back for some longer 6-10" branches to create a small berm on the edge of my rock "wall." I didn't have grass to cover it with so I'll be adding grass clippings and compost for a while.  After reading Paul's articles about Hugelkultur, I began telling all my buddies and even strangers on our local Nextdoor app. Some folks regretted getting rid of their wood so quickly. I felt pretty proud to be one of the first in my town to share Permies.com with others. Thanks for all the great input.

Paul,
Hugelkultur works great. I've been doing it for about 15 years.
On your page you say:

"Hugelkultur is nothing more than making raised beds filled with rotten
wood."

I might say 'rotting' rather than 'rotten' since even fresh green wood
can be used. Also it is not absolutely essential that the material be
covered with dirt. I have created wood "terraces" with any carbonaceous
material I could get my hands on...logs, brush, etc.....and raked the
annual deposition of leaves over the material. Here in NC, where we have
high precip and humidity, the material breaks down much quicker than it
would in, say, California. I grew fabulous pumpkins, for example,  in Ca
in the 8 month dry period (no rain at all) without irrigating. I used
everything organic I could accumulate, from logs to leaves, and laid it
out about 2 feet deep and planted into soil pockets.

Its amazing how the rotting wood becomes like a sponge. I can pull out
pieces that I buried two years ago and squeeze them to yield copious
amounts of water. Now when I look at wood, green or even dry, I think
"Water".

I tell my students that every unit of carbon incorporated into soils can
hold 4 units of water.

Penny Livingston, of Pc Inst of N Ca, had a few brush piles littering
her site but she didn't feel like moving or burning them, so she piled
on straw and a light scattering of soil, planted potatoes into it, and
harvested a couple bushels of spuds in addition to dissolving the "problem".

Here at Earthaven we have prohibited the burning of brush so the slower
biological 'burn' is our preferred way of managing it.

You will be greatly rewarded by using this approach. Thanks for the pix.

Idea here that I’m having a hard time finding something similar.

Let’s imagine, circular hugel beds forming a ring, almost pond damn like. Two entry ways. One for you. One for water to drain out of. In the middle of said ring is a small water feature for numerous reasons. Temp regulation, humidity, biodiversity etc.

Would this be a good idea? Worth the effort in building? I have yet to build a true hugel bed but have the opportunity to now and want to create something worth my time.

Thought?
Thank you!

Does anyone have any experience with or advice for building hugels with pine trees? BIG hugels. Something like the huge mamma jammas at Wheaton labs. I have an unlimited amount of pine now. Some hardwoods too. My main concern is acidity. Have been doing some reading about it & it seems not to be much of a problem once the wood has aged & decomposed some. I can help neutralize it with wood ash &/or agricultural lime if needed. So here's what I'm thinking ...

Dig a hole deep enough for one layer of green fully mature pine logs. Maybe 2 layers. Add a layer of the removed soil. Then a layer of slightly older pine logs. Then high quality top soil. As it gets taller & wider start using other woods along with even older pine. Plus some wood chips, mostly pine but with other woods mixed in. Along with plenty of topsoil to fill any gaps & between layers. This hugel will get exposure to some large commercial farmers, people with very large home gardens, as well as some influential people in the local ag & forestry industries. I need it to work to help change their more traditional way of doing things.

Is there any reason not to use mostly pine for this?

Pine has worked well in my experience. I’d avoid cedar or redwood. Also, I would not bury woodchips, and rather use them as mulch. Woodchips have a high surface area and often come from logs that have a much higher carbon to nitrogen ratio than branches and twigs that are the same size as the chips. Nitrogen deficits occur at the surface of the wood, but with large wood that surface is relatively small, and with little branches the cambium has more nitrogen. Chips on the surface have nitrogen from the air to pull from. Bury wood in as close to the form it grew as possible. Leave no wood exposed or it becomes a moisture wick and dries out the bed. Best of luck.

Interesting note about exposed wood being a moisture wick.  I had not read that before.

Thanks Ben. I had completely forgot about that issue with burying wood chips. We don't have much if any redwood or cedar. Mostly oak other than pine. Oak has been my main wood for hugels in the past & it works great. There definitely won't be any exposed logs or sticks. It will have a rather thick layer of topsoil for the outer layer. Plus mulch. I prefer leaves for mulch but might use aged wood chips for this particular project. It will be less fiddly over time & easier to convince the locals to try.

I haven't seen this with hugels, but Sagara at the East Devon Forest Garden uses earthwork banks quite a bit to create microclimates. In the centre of his garden is a circular bank enclosing a natural swimming pool. The reflected light off the water also helps to create warmer microclimates and he has lemons and olives ripening outside on the banks that catch the evening sun. I think using the hugel beds as microclimate altering features is a great idea - multiple uses!

Just remember wood floats, and therefore makes a poor dam wall unless it is completely and permanently waterlogged to the point it sinks. You mention drainage, so just make sure the wood can’t be lifted by water to damage anything downstream.

Very good points!  Also remember that wood that is completely waterlogged might take a LOT longer to decompose -- I remember a stone smith telling me that when they drained some of the water out of one of the fens that they started having problems with a couple of the old buildings because the pier timbers started to rot.  It was so long ago that I do not remember enough to properly fact check this, but decades ago it made an impression.

I’ve been working on a similar idea in that I’m wanting to raise the water level in my pond. Can a Hugelkultur be soggy? What type of edible plants would grow in this ? ( zone 4 )
