I have three varieties of tom in the GH this year: Marmande which are doing fine if a bit slowly, Yellow Brandywine and a black type called Carbon are healthy but worrying. The latter two (growing for the first time) have been in heavy flower now for at least a couple of weeks but hardly any fruit is set. I keep the GH doors open for insects and also go around a couple of times a day tapping the plants to generate the pollen. Because the Marmande seems to be behaving, I suspect these other varieties may be problem germinators... or is it just the awful weather?
Tomatoes not setting fruit
