Hot temps

18 years ago

I'm new to growing tomatoes, and I've learned a lot from this forum and the FAQs. But I'm a little uncertain what is meant when we're told that tomatoes won't "set fruit" at certain temperatures.

I planted my seedlings a couple of weeks ago--a few days after a late frost at the end of April. Now we are at 100 degrees in California, for the next few days at least. Obviously, it isn't 100 degrees all day. Will the tomatoes "set fruit" during the cooler part of the day? Or is the possibility of fruiting lost entirely for the buds at those temperatures? What will happen in 6 weeks when the temperature may very well be over a hundred degrees for a week or so (but again, not all day--though it may never get below 75, even at night)? Will my tomato production be affected in August and even Sept?

I know this is a good tomato growing region--there are large commercial tomato fields half a mile from me (and the grower set out his tomatoes at about the same time as I did).

My experience is that yes, when the weather gets really hot you can be witness to blossom dropping.During the night when it is cooler I'm not sure, I'm not positive but I believe that there is a certain temp. range in which blossoms set fruit better. But not worry, it will eventually (hopefully) cool down and fruiting will continue. And yes its been a weird spring in Ca. so far. Many other gardeners I talk to are seeing the affects too. I'm actually coming up on 80 days in the ground on three plants that went in late Febuary and just one single fruit finally set as of today. Dont believe anything you read about days to maturity, its all relative to whats going on around and in the garden. Anyways I'm rambling on, you will get fruit, just pe patient. Good luck.

I am in 8b and already seeing some blossom drop. It has been really hot and dry here so far this season (Central FL). Especially on my sungold it seems. I have a few trusses with only 2-3 tomatoes.
