what is the best way to construct a compost box at the bottom of garden ??

Answer 1

Bins need to be bigger rather than small. Ideally 3x3' and 2-3 feet tall. A pair is nice, you can turn the pile by forking the first ones contents into the next. I have a row of four. Plus one to hold browns til I get enough greens to add. Turning adds oxygen to the compost pile, which is good for the aerobic microorganisms that do the decomposition. It allows you to see if more water is needed as a dry pile won’t decompose. Then, the more we turn the compost, the more it becomes chopped and mixed.
Air is critical to keep the pile from smelling. A well maintained pile will smell like fresh soil. In fact it is possible to gauge green to brown ratio by smell. If the pile has an ammonia odor, you have too much green material (grass clippings, food scraps, green plant material) and not enough brown (dry leaves, woody prunings, pine needles, dried out plants). Add more brown material or soil.
If you get it to wet it will begin to decompose anaerobically and produce hydrogen sulfide, the rotten egg smell. The best thing is to turn it and get air in.
If you have to much brown it wont heat up. Add greens.
The ideal ratio of brown to green is dependent on the carbon and nitrogen in the material you wish to compost.
Green ingredients (grass clippings, weeds, kitchen scraps, coffee grounds, seeds, soft green prunings, rinsed seaweed, animal manure (sheep, poultry, horse, rabbit & cow))
Brown ingredients (dead leaves, straw, hay, wood shavings or chips, egg cartons, newspaper, paper bags)

Answer 2

I have one between two jade bushes, i just dug a hole about two feet deep and wide started throwing all the left over peels, coffee grounds and stuff, cover it with a piece of wood, cause it can get stinky, and all the worms, bugs, and mother nature will do there thing, and you'll have awesome soil for all the veggies you grow in about 3 months, my tomatoes are doing very well this year, with the compost i've kept.
