Compost Timing & Tips

Ever wonder how long you need to wait before your kitchen scraps turn into rich soil? Let’s walk through the basics, the signs of readiness, and a few easy ways to put that compost to work.

At a glance

A quick look at the timelines: a balcony bucket usually finishes in two to three months when it’s warm, and four to six months in winter. Worm bins tend to give you a first harvest after about two to three months.

How many days does compost take?

The speed depends mostly on heat, then on the size of the pile and how often you stir it. In a hot summer month a damp bucket that you turn weekly will be ready in about sixty to ninety days. In winter the same bucket can need four to six months, especially up the north where it may stall until March. A large garden heap that you turn often can finish in four to eight weeks because it heats itself up to fifty-five to sixty-five degrees Celsius.

Ready test: look, smell, feel

When you’re not sure if it’s ready, give it a quick look, smell and feel test. The material should be dark brown to almost black and crumbly, with no recognizable peels or leaves. Bring the nose close, it should smell like soil after a rain, not sour or ammonia-like. Push your hand into the middle; it should feel the same temperature as the air, and a handful should hold together loosely and crumble when you poke it.

Seed test

A simple seed test takes about a week. Fill one small cup with your compost and another with ordinary potting soil. Plant ten methi or sarson seeds in each, water them the same amount, and keep the cups side by side. If the compost cup sprouts as well as the soil cup and the seedlings stay green, the compost is ready for young plants. If the seeds rot or turn yellow, give the pile a little more time.

Sieving & resting

When the compost looks ready, tip the bucket onto a sheet in the shade and rub it through a wire mesh or a plastic basket with six to ten millimetre holes. What passes through is your finished compost. Anything that stays behind, twigs, avocado stones, unbroken bits, goes back into a new bin as a starter. Then let the sieved compost rest for about two weeks in a loosely covered bucket, keeping it slightly damp and out of direct sun.

Mixing into potting soil

More compost isn’t always better. Pure compost can hold too much water and become compact, which isn’t good for young roots. Use the same small bucket or katori for each part and mix by volume. A versatile pot mix is two parts garden soil, one part compost, and one part coco peat or clean river sand for drainage. For established pots, scrape back the top centimetre of soil, spread a one to two centimetre layer of compost around the stem, not touching it, and water.

Compost tea

Compost tea is simply compost soaked in water, strained and poured onto soil. It gives plants a mild nutrient drink. To make it, put one cup of finished compost in a cloth bag, hang it in five litres of water for twenty-four hours, stirring a few times, then pour the liquid onto your pots that same day. Skip any sugar or molasses, they can feed the wrong microbes.

Safety first

A few safety notes: wear gloves and wash your hands with soap after handling compost, especially if you have cuts. Make sure your tetanus shots are up to date, and wear gloves for all soil work during pregnancy. Dampen dry compost before sieving, and do the sieving outdoors so you don’t breathe in dust. If you have asthma, lung disease or a weak immune system, let someone else handle the dust-y part. Wash any herbs or vegetables grown in compost well under running water before eating, and keep small children from eating soil.
