If you have a smaller outside space or a compact area like a patio or balcony, you can still grow delicious tomatoes that look as good as they taste. The stay-green trait means the leaves won't yellow. TMV resistant. Harvest July-early October. Height 40-50cm (16-20"); spread 30-40cm (12-16"). Growing Information Sow March/April for greenhouse growing (or April for outdoor growing) in a propagator on a windowsill or pots or trays in a greenhouse at 18-21ºC using a good quality compost. Cover seeds with 6mm compost (germination 7-14 days). Transplant seedlings singly into 7.5cm (3") pots. Grow on, finally planting into large pots, or direct into a greenhouse border, or outdoors 45cm (18") apart when the risk of frost has passed. Feed regularly with tomato food.
