Tomatoes are Australia's most popular home-grown vegetable and arguably the most rewarding. The difference between a sun-ripened home-grown tomato and a supermarket specimen is profound. They require warmth, consistent moisture, and attention to pest management (especially fruit fly in QLD/NSW). Hundreds of varieties available from cherry to beefsteak, determinate to indeterminate, heirloom to hybrid. Grafted plants offer disease resistance for problem soils.
