Hügelkultur. The fine art of garden upcycling. In simple terms, it's a compost heap which you plant into. A kind of raised bed. The secret is the layers. You often start with big carbon heavy logs at the bottom, then maybe leaf mulch or grass cuttings then maybe cardboard, then maybe a thin layer of soil or upsidedown turf. It really depends what you've got to hand. Good layering gives a structure and the right nitrogen/carbon balance to control the breakdown.
For our operation, we started with a septic tank. Or to be exact, the displaced rocks that we needed to do something with. So they became a retaining wall. Then we needed to do something with the building waste from the house- broken tiles, old concrete floor screes. They became a hardcore base. Then our fig trees were totally overgrown. The thick woody branches became our first layer of organic material. Then the pudada (pruning) of the vines had to be dealt with, they went on next. Their long strands gaves us a good matted structure we could even walk on. Next we had a lot of grass cuttings. A 6 inch layer of this spread all over the top and I'm hoping they've create a good sealed oven like structure to initiate a hot decay beneath. Next we had to remove turf beneath the vines. So on went upturned grass and soil, further sealing in the breakdown processes below. Lastly I'm levelling a terrace for outdoor dining just above here and just outside of the wine cellar (for all those bottomless brunches); the displaced soil from this terrace is capping off the raised bed. Next year we'll start a proper planting plan once it settles. This year I'll throw a few wild flowers over it so we've got something to look at from the dinner table. 🍷🦋🐝🐞🏵. Pleased that we saved ourselves skiphires and bonfires and get something for it. Don't throw things away until you've had a very good think what you can use it for. Don't panic when you've got too much crap to deal with. Sit down, make a plan. See if your problems are actually opportunities. It's worth it in the end. @ Paço De Sousa, Porto, Portugal
