Amy Hepworth is a pioneer at Certified Organic farming in New York State. On July 21, 2012, Hepworth Farm hosted a NOFA-NY Field Day, where Amy Hepworth described the cultural methods and organic preventive sprays employed at this 300 acre organic farm, 25 acres are planted with tomatoes, to head off potential crop devastation from late blight.
Proper staking of indeterminate heirloom cherry tomatoes insures even growth as well as good air circulation. It also makes spraying the necessary preventive, OMRI approved, copper spray easier for complete coverage.
Amy Hepworth demonstrates a pruning technique which removes all of the bottom branches and leaves of a staked tomato plant. Also the soil in the aisles and around the base of the plants is lightly mulched with straw. This prevents fungal spores moving upward from the soil.
