Working with Nature: Observations from the Land

2026-06-29T11:20:58+12:00

By Merve Yeşilkır, Waikato Branch As tree croppers, we all carry that dream of having land that is both beautiful and productive, picking fruit, right and left through summer and winter. At the same time, there are moments of struggle, the amount of work that needs to be done, pests to tackle, and invasive weeds.

If you enjoy this article, consider joining us to receive our quarterly TreeCropper publication as well as more members' only content. Space in my suburban section is at a premium. Pragmatism has forced me into a one-out, one-in policy, so a recent kowhai wind fall came with a silver lining, as its demise was followed by a well-timed email from our local branch advertising a fruit tree sale.
