I have one on a grafted root stock and it starting dropping blossoms. I think it was a response to the 9 inches of rain we got in 10 days (one storm was 4.5 inches alone). I don't see any fungal infection and no discoloration of leaves. Just to be safe after such a deluge of water, I am now adding Tomato Tome fertilizer to the soil.

Ben Quisenberry, who got it from Doris Sudduth. It is temperamental here in NC, but when it is happy, it is superb. This year it has to share attention with over 200 other varieties!

Blossom drop is mostly a sign of an inappropriate temperature and/or humidity level when the flowers are open - it usually throws lots of blossoms, though, so eventually you will get fruit set.

One pod of them just all dropped last week, and it could have been the cool rainy weather. One day didn't even get above 60. I have both the potato leafed and non-potato leaf Brandywines growing. I have about 5 varieties overall, mainly just to ensure I get tomatoes that don't taste like paper this summer. I've had good luck with tomatoes overall in the past, though this is my first year with this many heirlooms.

Other things going are broccoli, cabbage, about 4 varieties of cucumbers, zucchini, and a few peppers. Peppers are tough to grow in New England, but I'm trying to get them going this year. Oh yeah, and tons of bush and pole beans.
