Educator shares home composting knowledge

Central Otago vegetable gardens could produce good yields next season, following the launch of a how-to video guide on trench composting.
Enviroschools facilitator Anna Robinson created the video during her time in lockdown to show people how they could create their own compost system.

Trench composting, one of the oldest forms of the concept, involves digging a trench-like groove into the ground, preferably your vegetable patch, which food scraps can be placed into and then covered with soil.
Ms Robinson used her own backyard to demonstrate just how easy and efficient it was.
‘‘I made the video in response to being stuck at home and not being able to get out and about and teach like I normally do,’’ she said.
It was also a way to help people deal with food scraps, which would be more abundant during the lockdown as people spent more time at home cooking.

‘‘I thought if we can do a little video about that and see how easy it is, it might also help [the Central Otago District] council’s rubbish pick-ups and [there will be] less food waste going to landfill.’’ That was where trench composting could help, she said. Not only was it good for the environment, but vegetables thrived in the nutrient-rich soil. ‘‘It’s the basic concept of returning to the earth things that were once living. ‘‘It creates fertility in our soils,’’ she said. ‘‘It’s so easy and effective.’’
