Dear Compost Doctor why won't my compost heap rot?.. my breakdown rate has broken down, despite vigorous stirring and liberal applications of shop bought compost accelerant...all I see is dried up grass clippings, the only sign of any change are the pale spots left by my dried tears... please, Compost Doctor can you help?
The Compost Doctor lifts a handful of the specimen kindly provided by Ms Cowgirl, lifts it to his nose and breathes in deeply closing his eyes. He nods sagely and then inspects the sorry sample separating the contents with his index figure. Finally his expression changes from one of professional appraisal to one of satisfaction as he sits down to write:
Dear Ms Cowgirl,
Calm yourself, all is not lost. Firstly I notice that this specimen consists predominantly of grass clippings which, whilst they will eventually decompose, are notoriously bad rotters - they are not the ideal basis for a beginners heap. I prescribe daily doses of mixed vegetable matter for this heap: peelings, salad, raw vegetables. If the grass clippings are dry it may be rather too late for them; but if you add a good moist mixture of vegetable matter you may save them.
Secondly, you don't mention worms. Brandling worms (pictured courtesy of British Worm Breeders) are a friend to compost, they are the best of all
compost accelerants. I wonder whether your heap is on a solid base or on soil. It wants to be on bare earth - break up the earth beneath it and then replace your container. If you provide plenty of good food for the worms they will repay your kindness by converting it into rich compost in half the time (did you know people actually buy worms for the purpose?). Incidentally, the addition of fresh horse manure will help to both encourage decomposition and encourage worms to join the fun - but don't forget to stir it all in.Thirdly I was worried by the dryness - decomposition occurs best in moist (not sloppy) conditions (though undisturbed grass clipping clumps have a habit of looking dry on the outside whilst being wet on the inside). Bottom line: if you are happy that your heap is well aerated and your grass is nicely distributed throughout, it may need watering. Watering your heap is a good thing; watering it with a naturally occurring solution high in nitrogenous compounds is all the better - see where I'm going?
In summary, Ms Cowgirl, compost, like most of us, likes daily love and attention. Invest time and a good melange of vegetable matter in your heap and your reward will be great.
Lots of love,
Compost Doctor
I told the Doctor that I didn't think his signing off was quite professional but he insisted. Watch this space for more compost diagnoses.
