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. The solution often seems to be finding a teacher who has figured it all out, someone who understands every detail and grows so successfully that plants thrive wherever they go. Although this sounds idyllic, that teacher is very real and accessible to all. Papatūānuku, Pachamama, [...]

2025-09-18T14:50:23+12:00

Young grafted Harricado tree The Harricado is a chance seedling discovery from the suburbs of Nelson. Harry Pearson, member of the Nelson branch of the New Zealand TreeCrops Association (NZTCA) bought a property with an established avocado tree that bore an abundance of large avocados.
