A local gardening expert says blossom end-rot on plants, especially tomatoes, is not unusual this time of year. Tom Hartman of Hartman’s Towne and Country Greenhouse said on WOMT’s Be My Guest, the problem shows up on the first tomato or two, especially in containers.
Hartman explains it’s not a disease, but rather a calcium deficiency in the plant, enhanced by the watering process.
He says gardeners can purchase a product containing liquid calcium in a bottle that can be sprayed on the plant. Hartman explains that a tomato blight on the leaves has also been noted locally this summer.
