Composting walk at RECG – write-up

A couple of weeks ago, I arranged with for one of Changeworks’ master composters to visit the Royal Edinburgh Community Garden. Am very grateful to Kathleen at Changeworks for sorting this out, and to Alexey for giving up an afternoon to talk about compost.

It was a drizzly day and only a couple of people were at the garden, so Sean was able to give us a tour of the gardens and reflect on the composting opportunities (or lack thereof) at various sites.

Here’s some notes from the day:

  • I had originally thought that the large amounts of green waste at the North of the site might be used for creating a hot composting project to obtain a yield. Even though there’s a lot of green waste, it turns out to be low quality and of mixed provenance, so the general feeling was that it’s not worth using at the moment. It’s better to work with smaller amounts of high quality, known provenance material which is easier to work with, should make a better compost and reduce the risk of contamination.
  • There is a new volunteer — Andy — who’s starting on site. He has over 20 years experience of working with compost and wormeries, so should be able to give good advice.
  • There’s lots of comfrey around, so there’s scope for making comfrey liquor
  • The nettles in the orchard will be managed this year, and areas will be cut to provide different sward heights. There’s not been a decision what to do with the cut nettles yet. Leaving them to recycle where they lie is an option, so we’d have to suggest a better alternative if we want to use them.
  • There’s an earth pile by the top field that has both comfrey and nettle growing profusely out of it; I may take bets on which plant will out-compete the other
  • Sean has a small electric chipper, but a petrol one would be needed for any major chipping project
  • Sean was interested in the hot composting and I have a compost thermometer as part of my numeracy work at the Grassmarket Community Project – I’m going to think about a numeracy and composting module

One of the highlights of the day was walking down into the orchard through a light drizzle and seeing the apple trees covered in lichen. Resplendent, even! There’s a lot of lichen on the trees for a city site, and the moisture in the air made the lichens a vibrant green.
