No worries Nancy. My BW's experienced the same thing and eventually out grew the blossom drop thing. How long has it been since you put them out. It took mine about 5-6 weeks after I planted them out before they started seting fruit.

Actually, I put it out as an 8" start the week of April 15th (our last frost). All the other maters are doing fine and have fruit coming along great, except 1 roma that withered up and died for no apparent reason.
I did toss some finished compost around all the plants this year (FAQ mentioned too much N), but, as I said all other plants are fine.

Well your BW's have been out much longer than mine. As you probably know BW's are a bit tempermental. Your weather report is the same as mine . My BW's did drop a few blossoms but also continued to set fruit. Hmmmm.....

my first BW was pretty tempermental too. dropped a lot of blossoms, and those that made it are pretty catfaced. new fruit looks better tho.

My experience this year has been the same as schwankmoe. Dropped lots of blossoms, and the first fruit that did set were catfaced. The second wave of fruit looks much better. I was getting worried about the Sudduth's. It was putting out lots of foliage and dropping blossoms, putting out ugly looking fruit, and I haven't fertilized or amended the soil at all. I just noticed a day or two ago, that it's actually setting a new wave of fruit that looks much better and more plentiful than the first wave. A late bloomer, if you will. :) People say Brandywines don't like the heat, but I think it actually helped mine. Temps were VERY mild here in June, when the tomatoes first starting setting. A few days in the high 80's and into the 90's, and they are loving it.

Me too with the brandy-bloosom problem.

I have four brandywines growing in pots on a third-floor balcony, overlooking the harbor, on Cape Cod. They have an abundance of flowers. They don't seem to be dropping the flowers, it's just that no fruit is coming of them after about two weeks of all these flowers. There are other tomatoes out on the balcony also--juliets and Mr. Stripey and Mr. Fasano plum--and they are setting a reasonable amount of fruit so far, but not very many. Plants are all extremely healthy looking, very big, and staked. A lot of wind up here, and rain lately, but being pots, with holes in the bottom, I don't think they're water-logged.

The bees don't make the trip up here very often, but there's an abundance of wind. So I assume it isn't polination.

Two possibilities: too cold at night? It's been about 60-64 degrees for two weeks at night, 70-82 during the day.

Also, too much nitrogen or not enough fertilizer? I haven't fertilized in three or four weeks, and am about to use a low-nitrogen one. Isn't it fair to assume nitrogen is not the problem if the plants haven't produced an abundance of new foliage over the last two weeks?

I'm inclined to think more fertilizer or warmer nights are in order.

Anybody with advice, I'd be grateful. Zero experience with Brandywine up to now.
