I know..........this blossom drop thing sucks, I feel you on that one! I have BW's that are doing very well but dropping blossoms at an alarming rate. I have four BW's that are almost 4 feet tall and have only one fruit to show for. But after talking with a few people about this I'm confident that my BW's will out grow BD (fingers crossed)! We also have to keep in mind that BW's can be very temperamental plants. I wish nothing but the best of luck for you and your BW's!

High temperatures can cause blossom drop. Blossoms will also drop naturally if they are not fertilized. High nitrogen fertilizer can also trigger it. What are the N-P-K numbers for your fertilizer?

Say, Kubotabx2200, I've been following some of your other posts and wonder if you could advise.

I live at the end of Cape Cod, somehow three zones away from you although quite nearby as the crow flies. The moderating breeze keeps it from getting terribly hot here, as you probly know. My Brandywines, in pots, on a balcony, look great, and the blossoms don't fall off, but they're still sans fruit, at this late date. It is cooler here than other places, I know, but not below 55 at night. I've been underfertilizing in my pots maybe, but I wanted to know specifically if in our region you've found that an addition of phospherus will SOLVE the problem, or if it's a just a good necessay nutrient that prevents the problem from arising.

Up here on the third floor there's great sun and wind, but no bees, although I kind of don't think that's the problem, given the tomatoes on my non BWs up here are settign fruit, if not tons of it.

Any advice?
