My cherry tomatoes are still growing and producing. They probably will continue till the weather gets cold enough that soil temperatures drop.
However they do need some TLC now.
Any small ‘non producing’ branches that start to turn yellow, need to go. This allows more light through the bush to ripen the fruit. Also it stops valuable energy being directed to the small branches – all goodness needs to go to fruit producing and growing.
Looks more attractive too.
Place the removed branches into the compost or even toss onto the ground to break down over time (or do both).
The sweetest cherry tomatoes in my opinion, have always been the ones people have grown at home.
