Shirley F1 tomato is one of the most popular hybrid varieties, that is early into production with large trusses of medium size fruits on strong plants. This cordon type tomato has fast become an exhibitors and home gardeners favourite because of the high yields of very good quality fruit that shows some resistance to Tobacco Mosaic Virus, Cladosporium ABC and Fusarium. WHEN TO SOW
January to April
WHERE TO SOW
Sow seeds underglass 0.5cm (1/4 in) deep in pots or trays of good seed sowing compost and lightly cover with a sprinkling of vermiculite or compost. Place containers in a propagator at a temperature of 18–21°C .
WHAT TO DO NEXT
Prick out seedlings, once large enough to handle, into 9cm (3 1/2in) pots. Transplant to the greenhouse border soil, or individual large pots, or 3 plants per growbag when 20cm (8in) high. Can also be planted outdoors once all risk of frost has past. Plants require sideshooting and support for the best yields. Water and feed plants regularly with a high potash feed once the first truss has set.
