Gigante Liscio is a large round salad tomato from 1920s that has been reselected for good flavour, round shape & strong plants. Maincrop vine.
Requires a rich well-drained soil in a warm sunny position.
Tomato plants are not frost-tolerant and generally need to be started off in a greenhouse in the spring if they are to succeed outdoors in Britain. They also need a hot sunny summer if they are to fruit well.
Tomatoes grow well with asparagus, parsley, brassicas and stinging nettles. They are also a good companion for gooseberries, helping to keep them free of insect pests. They dislike growing near fennel, kohl-rabi, potatoes and brassicas (this is not a typing error, merely a difference of opinion between different books).
