Walking through the woods a couple weekends ago with family, we came across an area of Pa Pa’s property that we hadn’t visited before. It was a far corner along the property line, the woods there so thick and close that the light was dimmed at least by half by the canopy above.

The wood’s floor was deep and spongy with leaves- even the usually prolific Poison Ivy and Virginia Creeper wouldn’t sprout; mosquitoes were abundant, we could smell the leaf mould and wet permeating everything. Many scrubby cedars stretched up to the canopy, struggling for light but found little in the understory of taller trees. As a result, only the branches at the very tops still remained green and held needles; all the lower branches within reach were dead or dying and brittle to the touch. We pushed through to the edge of the property line and began to back track, when we came across several large mounds of earth in our path.  The mounds were 3-4 feet high and about 10-12 feet long. Rocks were piled on top of one of them as if to mark that spot. The larger two mounds were planted at the foot of a big cedar, this one towering over its straggling, sad looking younger cousins.

Shawnee are common in the St. James area and I had already spotted multiple thong trees pointing in the direction of a dry creek bed nearby. My sis in law speculated that they might be burial mounds. Under that darkening canopy, with sounds of water, critters chewing away at the rot and squirming about under a foot-thick carpet of decaying leaves and spongy wood- the idea of burial mounds seemed not only plausible but very likely. We also kept hearing something near us like footsteps or small rocks being tossed… but each time we stopped to listen, we heard only insects chewing and the whining hum of mosquitoes trying to feast on our ears.

I climbed to the top of one of the mounds so that I could look at it from a bird’s eye vantage point- it occurred to me that this would be rather irreverent if these were graves. Looking down on them though, they looked less like burial mounds. They reminded me more of  my Great Grandma’s old root cellar. We found four mounds in sets of two. They were placed with a space between them almost equal to the width of each mound. The tops of the mounds were squishy; the soil rich, deep and covered in moss.

We walked in the direction the thong trees were pointing after examining the mounds. Most of the thongs were in mature oaks that I’d guess their age to be about 80-100 years. By the way, I found this little guide from Missouri Conservation most helpful in guesstimating the age of  trees without counting rings: http://mdc.mo.gov/your-property/your-trees-and-woods/backyard-tree-care/how-old-tree

After traveling downhill for a bit, we came to what I expected to find, which was a creek bed. It was dry though, no active spring feeding into it. We wanted rocks to take back with us and had ridden down to that part of the property on Pa Pa’s 4-wheel drive mule, but I wasn’t sure that I would make it down to the stream-bed through all the thick undergrowth and trees. We opted to backtrack to the field and look for the source of the stream instead. We found it, at the bottom of a wide ravine that allowed a perfect size space to park the ATV in.

At the top of the stream bed, there was a dam. It had been built of stacked rocks, earth and chunks of concrete that I noticed were decorated with bits of glass. The dam was about 5 feet at its widest point and spanned the bottom of the ravine like a bridge. The rocks I found there had mineral deposits that reminded me of the formations you see in the caves around here- I took one back to the house and Thurman said it had a lot of iron oxide in it and a fair amount of pyrite. It was a REALLY heavy rock for the size that it was. I also brought back another monster rock, which Miranda had to help me lift into the back of the mule. I’m still trying to decide where in our yard I want to park it. For now it’s sitting near the frog pond, since that is as far as I could carry it myself from the trunk of our car. :-p

When I got home, I decided to do a little research into what those strange hills in the woods might be. My husband read a fair bit about Shawnee burial mounds. I started looking at different types of root cellars. It was during my browsing of root cellars that I stumbled across pictures that looked EXACTLY like our mounds. 3-4 feet high, paired in sets of two, at the base of large trees. The word under the caption was Hugelkultur, which is a German word for “Hill culture.”

There has been a lot of interest in recent years regarding perma-culture, or permanent, sustainable methods of gardening or small scale farming. I’ve heard gardening called a “retired person’s” hobby, it’s coming back into vogue thanks to the popularity of survival-ism and prepping. Hill culture is method of lasagna gardening, which is layering different materials for your garden bed and planting right on top of the layers, then allowing all the materials to compost there in place. It’s less labor intensive than building compost piles and turning, watering and caring for them every day. The material breaks down slowly, feeding the plant roots on top as it turns into compost. The mounds we found in the woods would have broken down over time, spreading out and losing height as the bulky inner layer decomposed. After I read how Hugelkultur mounds are built, I understood why they felt spongy when I stood on them.

The inner layer of a Hugelkultur mound is bulky, rough material- such as tree trunks and limbs. Over this you would add a layer of a slightly lighter compost material- straw, chopped leaves, grass clippings, sod, large vegetable scraps, newspaper, cardboard, etc. Soil amendments can be added on top of this layer. I’ve read that the first couple years, nitrogen rich additives may be needed, since the tree trunks will absorb most of the free nitrogen in the pile until they reach saturation and begin to break down. Blood meal is great for this and relatively inexpensive. If you have access to manure, it’s full of nitrogen. Plants in the Legume family will also add nitrogen to the surrounding soil.
On top of all this bulk, you would add your actual soil. I have mostly clay and rocks here, so I’d probably use a mixture of purchased garden soil from the nursery, cut in half with some native clay. Clay is wonderful for holding nutrient value, it just sucks for drainage. Add plants, then mulch well as the final layer.

The mounds are built in pairs at an angle where the sun will pass over them side to side; some pictures I saw used  trees as a wind break on the north. Some left the space between the mounds empty so that every part of the hill was easily reachable. Others used the middle space for extra compost and added this center to the tops of the mounds as it broke down; this would give the hills a constant source of renewal and nutrient build up.

I’ve already chosen a spot in our yard where I intend to try this out. Even though I have a commercial drum-style composter, I would love to see if Hugelkultur gardening is as pain-free as its proponents claim. I already build raised beds for practically everything I grow in our yard, since few plants really love the rocky, clay soil. Plus, tilling clay only serves to dry it out and completely strip it of any nutrient value. A tilled garden simply wouldn’t work well in our yard. I tried it a couple times, then my tiller was retired to the shed up the hill after about 3 uses, it will likely see a revival only if we move.

I know our local Amish and Mennonites are genius when it comes to growing anything- if you’ve ever had one of their tomatoes from Farris Fruit Market in Camdenton, you’ll stop in there JUST for those. The Amish on Pa Pa’s property would have been the ones who built these mounds. I’m guessing they might have also dammed that spring, maybe to create an artesian well, in order to water their gardens.  I’ll post more pictures when I get back up to St James and can visit the mounds with a camera in hand. When I build mine, I’ll try to do a step by step write up on what I put into them and post later on whether or not they were superior for growing plants or not.

This site has some really excellent information about Hugelkultur and a ton of photos if you’re interested in learning more. http://www.richsoil.com/hugelkultur/ It also shows the progression of the mounds in graphic form, from year one all the way up to 20 years.
