‘Oh Happy Day’ is a cross between a very blight-resistant North American variety and a tasty French Marmande type. In T&M trials, ‘Oh Happy Day’ resisted blight infection for three weeks longer than ‘Mountain Magic’! Clusters of 3-7 tomatoes, each weighing approx. 150g have a fabulous balance of sweetness and acidity. Grow as a cordon outdoors and best ‘stopped’ after 5 trusses. Excellent resistance to both early and late blight.Sow seed on the surface of a good, free-draining, damp seed compost and cover with a sprinkling of vermiculite or compost. Place in a propagator or seal inside a polythene bag and keep at 20-25?C (68-77?F) until after germination which takes 10-14 days.Transplant when large enough to handle into 7.5cm (3in) pots. Plant outdoors once all risk of frost is passed 60cm (24in) apart. Plants will require sideshooting and support. Water and feed plants regularly with a high potash feed once the first truss has set.
