At this work day, we got a new compost pile started, and cleared an area to start building permanent compost bins out of the wire we have salvaged from the fence. We began lining our keyhole beds with stones to define them, and building mini terraces across the slope with the larger rocks and concrete chunks we have dug up. These will stop the sheet mulch beds from gradually migrating downhill. We discussed renting a pole chain saw and large chipper to turn unwanted tree limbs into mulch.
This meeting was held on our farm site in Lakewood.
We got another hugelkulture started at this meeting. At present it is a large half dug hole, with a pile of cut up brush next to it. We hope to finish it next time.
Also, we found it is very hard to build hugelkultures with our current number of members. The amount of ground covered each time is very small with this technique, whereas sheet mulching is faster, letting us compete more beds before Winter sets in. We probably will not build any more of them this autumn unless we can find some more local members. (Our membership is scattered across the Metro area.)
One of the reasons that hugelkulture building is so difficult here is that there are a lot of rocks in the soil, some of them very large. These take a long time to move, with only a small space gained for each. They will, however, be very effective at forming warm microclimates once we get them out.
We could, of course, do sheet mulch beds instead of hugelkultures. However, hugelkultures have a lot of benefits, particularly on this site.
And it would be easier to build hugelkultures at ground level, and pile imported top soil over them. But there is very little high quality top soil in Colorado, it costs money we don’t have, and the beds would probably be more drought prone that way, since roots would be less likely to move below the preexisting surface.
We plan to replace our rather messy temporary sign with something more elegant, especially so the neighbors don’t have to look at a piece of painted plywood against a tree all the time.
