It has included in-store promotions, cookery demonstrations and visits to growers for school children.
As Grower went to press, chefs at the Houses of Parliament were due to whip up tomato dishes in three Commons restaurants featuring the best of the British crop.
BTGA representative Julie Woolley said: "It's a challenge for the BTGA to continue to raise the awareness of British-grown tomatoes every season and during March we were delighted to take part in BBC programme The Great British Food Revival. The simple message in this excellent series was buy British produce or lose it altogether."
The BTGA is also attending the BBC Good Food Summer Show at the NEC on 15-19 June, when it will trial a heart-shaped tomato being grown for BTGA by Flavourfresh Salads in Lancashire and hold a competition to name the new variety.
