I dont know whats going on

My dwarfs are refusing to set flower. My micros are all setting and giving fruit but the dwarves keep dropping them.

I have so many leaves and only 3 fruit.

I have them in the sun in my balcony in 4 gallon pots next to the micros. They did get white fly Idont know if that could be the issue?

Any thoughts on causes for flower drop?

Thanks!

What varieties and what's the temperature and humidity.

I have tasmania chocolate, rosella purple, summertime gold and sweet scarlet.

Im in US zone 9b with a lot of morning marine fog. Temperatures have been mild like around 15-22C in the spring and 15-25C now in the summer.

Tasmania is the only one that has set 3 fruit. The rest nada.
The micros are doing fine though setting a lot of fruit.

Well the temperature doesn't seem too high but the morning marine fig may have something to do with it.
Lack of pollination due to high humidity and a wee bit cold at night.

Thanks worth

Just checked with some tomato growing coworkers and seems everyone in my area is having a bad season. So i guess the good thing is that is not just me messing up.

It could be the humidity. Try pollinating them with an electric toothbrush or a tuning fork in the morning. Just touch each blossom for a second or two to get the pollen to drop down onto the stigma. Some people will hand shake the plants but in this situation I would be a bit more aggressive.

I had the same problem with the dwarfs I grew, mainly Rosella Purple, Sweet Scarlet and Adelaide Festival. Pink Passion did well and eventually EM-Champion started setting after a lot of blossom drop. I'm in zone 8a.

I do wonder but the micros had no issue. I usually hand shake them but will use the toothbrush see if it helps with whats left of the season ( not much).
