Digging a trench alongside your vegetable bed is an easy way to dispose of food and plant waste, and enrich soil for next year’s crops

On a visit to our friends’ house recently, the subject of food waste came up. They haven’t got a tucked-away spot to set up a compost bin or heap in their garden, and their local council doesn’t collect. They had put their effort into bokashi composting in the past, but with a baby on the way I suspect they’ll have more than enough to do without taking on the added responsibility of caring for a bucket of fermenting kitchen scraps.

But as they’re already accustomed to burying their bokashi-ed vegetable peelings, it got me thinking about how low effort and high impact trench composting can be for those without room for a larger system. Trench composting is the simple process of putting your compostable matter – fruit and vegetable waste, plant material from the garden, grass clippings, leaves, etc – into a trench near where you’re planning to grow your crops next year. Over the coming months, this organic matter will slowly decompose, enriching the soil and improving its structure, making it ready to welcome the following season’s plants. No further effort is required from you to engage in this ancient approach.
