The green directory at www.sust.org

The green directory at www.sust.org

The good news: for the categories I know about (allotments, compost, permaculture, recyling) the entries consist of the usual suspects with one or two additional organisations. I’m confident that the other categories (another 50) will be a good starting point for future investigation, and a quick browse brings up a wealth of information. There are some nice introductory sections.

The bad news: as there’s no timestamp on the entries, they could be out of date e.g. LEEP is in there rather than changeworks. Most of the subject heads have statistics and quotes from 2003, so I wonder whether this project had particular capital expenditure but no more. Not found any broken links on my non-rigorous check.

Seaweed

28 October 2007

Can’t recall why I started getting interested in seaweed as a green manure, although it came up in conversation on Monday night. One of my colleagues was talking about taking a cycle ride along the seafront from Edinburgh out to Seaton Sands, which opens up the possibility for doing a run out to collect a trailerful of the stuff.

Seaweeds and their uses, Chapman and Chapman. CEC Central Lending Library, shelfmark QK567. Technical book; reporting and links to research; graphs and tables; relatively old.

Mostly brown algae, wracks and oarweed has been used as manure. Driftweed or cut rockweed. It’s mainly used close to the coast as seaweed is approx. 90 percent water. High potash content (K) so good for plants that require high K: roots and fruit, esp. blackcurrants. Low in phosphate so must add it if seaweed used exclusively for long time.

N Phosphoric acid K Salt
wet weed 11 2 27 35
manure 11 6 15 -

Advantage of being free from weeds and fungi.

Seasonal variation: research shows higher content of minerals around March; lowest around October.

So … it’s actually seaweed as a brown manure. Quite different from getting well-rotted manure from Gorgie City Farm at £2 per bag. Telephone 0131 337 4202.

Organic Gardening; Plant life of Edinburgh and the Lothians; A Scot’s Herbal; Joy Larkom: all these references seem to indicate that seaweed is full of trace elements and so is useful for poor soil but doesn’t make much difference on good soil.

The self-sustaining garden (a guide to matrix planting), Peter Thompson

22 October 2007

Another book borrowed from Edinburgh’s Central Lending Library, shelfmark SB473 (or AH4 in the new system).

An intriguing book. Written from a gardening point of view with reference to plants and their visual and aesthetic structure, it makes the argument that one should minimise inputs, intervene in the landscape minimally, choose plants that complement each other and the microclimate they inhabit. It’s all reminiscent of permaculture, yet there’s not one reference to permaculture or any of the permaculture big names in the acknowledgements. There’s no references to productive plants, either, so it’s not one for my bookshelf.

Encourage the plants you want; discourage the plants you do not want.

Can’t say fairer than that: it’s not saying eradicate plants that don’t fit! He then ranks plants into 9 categories, from the most vigorous through site-appropriate to inappropriate:

  1. out-and-out weeds with vigorous powers of regeneration (bramble, stinging nettle)
  2. plants that are out of place and pose a threat to the planting scheme (dandelion, ground elder, rosebay willowherb, blackthorn, ash)
  3. Weedy but not threateningly invasive; better out than in
  4. Plants with attractive qualities but an inclination to take over
  5. Long-lived tenacious plants, appropriate to the site and largely self-maintaining
  6. Plants appropriate to the situation but unlikely to survive entirely unaided
  7. Plants whose survival depends on intermittently repeated regular attention
  8. Plants dependent on regular attention over indefinite periods for survival
  9. Plants unable to exist without frequently repeated, time-consuming attention

Nice chapter on soil and indicator plants. Lovely illustrations. Has case studies from halfway through the book and the last four chapters are dedicated to particular habitats: variations on grassy themes; garden pools and wetlands; the mixed border; the blessings of shade.

More reading required!

26 July 2007

Looks like my review of Graham Bell’s book is quite high in the google ranking. I enjoyed reading it, and I enjoyed writing the review and now there’s some feedback from the blog stats and google.

One of Nielsen’s usability articles reckons that one should write articles with content rather than hastily-written blog posts. Isn’t that obvious? Whatever… it’s certainly bolstering the fact that I could do more reviews and stuff.

The permaculture garden, by Graham Bell

21 May 2007

Borrowed from Edinburgh Central Library, this book is clearly a reference book as there’s so much in it. From large scale projects for a row of terraced houses to a chapter full of ideas that can be completed in a day, it has an informal style and a can-do attitude. The book also has 24 tables of plants suitable for a variety of uses; my only criticism is that the tables don’t get a mention in the index or table of contents.

The inspiring illustrations by Sarah Bunker are clear and complement the text well. She describes permaculture techniques and imagines community living (in the vein of Clifford Harper). It appears that she’s author of Diggers and Dreamers, listed on lowimpact.org. (TODO: explore this site)

Two themes running through the book are edge and height. Taken from forest gardening, the book advocates making structures in the garden to maximise the use of these two components. Another theme is making do with what’s there and reducing inputs — permaculture.

The book is published by Chelsea Green Publishing, who see publishing as a tool for effecting cultural change and want to stop the destruction of the natural world by challenging the beliefs and practices that are enabling this destruction and by providing inspirational and practical alternatives that promote sustainable living.
