Not having much luck with my tomatoes this year. When it got wet in early summer, I noticed my bush Roma plants were looking unhealthy, leaves starting to develop brown, yellow patches, holes etc. I did some pruning to get the leaves away from the soil, suspecting blight, and they did start to improve - I suspect thanks to the hot spell.
Now the weather's been more changeable, they've worsened (again I've got rid of affected branches) and more worryingly, a lot of the green fruit have got distinctive black 'holes' on them. A few flowers and their stems have also withered and gone brown.
Looking around, seems pretty clear this is bacterial spot, not blight. I've tried using a baking soda spray but suspect I'm too late. I'm wondering about spraying with Bayer Fruit and Veg fungus stuff too?
I've got 3 Roma bushes and then 10 assorted vines, which are healthier... But similar symptoms are now starting to develop.
Any thoughts/help greatly appreciated! Should I give up on the Roma bushes? They're pretty heavy with full size green fruit, and fresh growth is still coming. If I get some of the Bayer stuff, could that turn them, or at least the vines around?
