The Miracle of Compost

~ November 9, 2011

I believe this is the most wonderful time of the year. Not only are the Holidays fast approaching, it is also time to experience the miracle of composting season.

It is fitting that you do two things this time of year to celebrate the great composting season:
#1 empty your composter if you have not done it since last fall
#2 fill it again.
Empty it.
When you remove the composted material from your composting unit (or pile….) be sure NOT to spread it like salt and pepper all over your yard. Compost is not a condiment. It is the meat in the sandwich. It provides the lifeblood for all plant life in your garden by feeding the micro organisms that support the perennials, annuals, vegetables etc. that you plant out there.

I spread finished compost 3 to 5 cm thick (1 to 2 inches) all over my garden this time of year. In most cases this means that the contents of your composting unit will not go very far. That is o.k. as you can buy more or spread next years’ compost supply over another part of your yard next fall.

Fill it.
1. Put a shovel full of finished compost in the bottom of the composter. This will help to ‘get the party started’ - in other words, the beneficial bacteria in the compost will initiate the decomposition process.
2. ‘Layer’ your compost beginning with a thick layer (10 to 15 cm, scrunched down) of ‘brown stuff’ – fallen leaves is the #1 brown stuff of choice. You can use shredded newspaper if they are scarce in your area.
3. Next layer is ½ as thick of ‘green stuff’. Finished tomato plants, annuals, grass clippings or kitchen scraps will do the trick.
4. Continue to alternate a thick layer of ‘brown’ with a ½ layer of ‘green’, pushing the contents into the composting unit as you go to maximize the volume in it.
5. Add water as you go….. it only in the presence of moisture that decomposition takes place. Pity the poor people in the desert that try this….
6. Add Green Earth Compost Accelerator every 2 to 3 layers to speed up the decomposition process.

If your composter has a lid, put it on the unit but only if you have pre-moistened the contents! Remember, dry stuff just sits there! If you composter does not have a lid, no worries. I don’t really get the point of the lid anyway, except that it ‘neatens’ up the look of the unit.

Siting your compost.
Position your compost in as much sun as possible and as close to the kitchen door, for convenience. You can add compost all winter long, regardless of where you live in Canada. While it will freeze solid in most regions, it will also thaw in time and when it does, the greatest decomposition occurs. The frost ‘rips and tears’ the cell structure of the organics that you place there: the warmth of spring will activate the ‘good guys’ that do the breaking down of the works.

What to put in:

Anything organic, providing that it is NOT any of the following:
- meat or meat byproducts
- cat and dog droppings (or any meat eater, for that matter)
- dairy products
- wood, bark, metal or plastic
- weeds that have gone to seed (though, I break this rule all of the time)

Back to the beginning: when you spread finished compost over the surface of your garden you encourage earth worms to come up and pull the compost down into the soil. They eat this stuff; convert it into organic, nitrogen rich earth worm castings that feed the soil. Earth worms also open up the soil, allowing oxygen to flow to the root zone of your plants. (Note: all plants need oxygen at their roots.)
And finally, there is the wonder and awe of watching what WAS something recognizable, like leaves, banana peels and grass clippings, convert into the useful soil additive ever created. Your plants thrive: they grow faster, resist insects and disease and they produce flowers and fruit like never before. They are happy.
And all you did was organize ‘waste material’ into a pile or composting unit and wait.

THAT is the miracle of compost.
