My tomatos are dropping blossoms. Could this be from the cold nights we have been having? The low last night was 46, but it is grtting into the 70s or even low 80s in the daytime. Do you think spraying with blossom set would help? I think I will give that a try.
The most frequent cause of tomato blossom drop is temperature.
•High daytime temperatures (above 85 F / 29 C)
•High Nighttime Temperatures (Below 70 / 21 C)
•Low Nighttime Temperatures (Below 55 / 13 C)
“Do you think spraying with blossom set would help? I think I will give that a try.”
We’re having the same problem here, and I’ve sold a lot of blossom set spray this season; more than normal. And, yes. It’s due to the cool nights. And drought also effects blossom set, as does too HOT of weather. You can’t win, LOL!
It’s up to you. I sell it because people want it, not because I, myself, use it. No one has come back to me in nearly four years and said, “This stuff don’t work” so it must work!
