Hello, I’m Alexander White, a senior agronomist with 30 years of experience as a vegetable grower.
I’ve grown vegetables in nurseries, greenhouses, open fields and even soilless substrates, using organic, biological and conventional methods.
Growing your own vegetables should be rewarding, not frustrating. I share what three decades in the field have taught me, so home gardeners and small-scale growers can spot problems early and fix them with confidence. From identifying a pest or disease to choosing the right treatment, organic or conventional, you’ll find clear answers in my blog, my pictures library and my courses on Udemy.
