What has your weather been like? High temperatures, low temperatures, high humidity will mess up the pollination of tomato and pepper blossoms. Since the blossoms don't get pollinated, they turn yellow and drop off. All you can do is wait until sufficient weather for good pollination. Hang in there! :wink:

Night 18C.

Day in the sun even 40C.


I think the flowers are dusty, you can see on the 3rd picture.

I'm afraid I can't read Celcius. I only understand F. But obviously something is causing the blossoms to not pollinate. The temperature or humidity is got to be the cause. Have you been getting a lot of rain lately?
But pardon me for admiring your greenhouse. 😊

You're not the only one. One website I looked at says 40C is 72F, which is quite wrong. The proper answer is 104F. Obviously someone neglected to add the 32 Fahrenheit degrees which is zero on the C scale. Here's a better site:

If the air temp outside was 104F (?) I wonder what it was inside the greenhouse. A bit too hot for tomatoes I imagine, but maybe I'm misunderstanding what the conditions really were. I do think I see some shade cloth on the roof.

Yes, that's a very nice greenhouse, majmaj. Did you design & build it yourself?

If the temperature outside is hot, then the tomatoes won't need a greenhouse. The extreme heat would cause blossom death and drop. Do you have a thermometer inside your greenhouse?

Yes, I have a thermometer, on hot days in the greenhouse it is even 104f.
I built it myself.

That extreme temperature is causing the problem, then. When it gets that hot, your greenhouse either needs to be taken down like I do mine, it have more doors or windows that can be opened to ensure adequate air flow. A fan may also help blow out the heat.

majmaj, we've had tomatoes survive 40C summers in the past although some got sunscald (? - white patches on the skin) & had to be shaded. But by then fruit was already growing.

(Edited) ... Maybe they're only damaged by high temps in the earlier stages.

Where are you located and what's the weather going to be like for the rest of the season? I wonder if the plants might make more flowers given some cooler weather.

By the way I'm no expert, except in terms of my own experience but with limited attention to detail.
