Man, those are pretty cucumber plants! Mine are not doing well at all. Usually they produce like rabbits, but we're just barely getting enough to eat. The plants are turning yellow and dying for some reason. I replanted the cukes, hoping maybe they would produce something by this Fall. The tomatoes have done really well this year though.
When I hear yellow and dying makes me think fungus. We have high humidity here in Michigan which promotes fungus growth.
The TSC cattle panels for tomato cages is a good idea. Do you have a photo of one? I have thought of doing this myself.
Yeah, that makes sense. Humidity is not normally a problem here, but this year we have had a lot of rain...my farmer friend says he lost 35 acres of Alfalfa because of the rain. I love the Heritage tomatoes, but I don't have much luck growing them here. I plant a variety called "Super Fantastic" which are very disease resistant and will almost always give me a crop.
I Planted a few super fantastic this year. So far they look really good. I don't have much luck with heritage tomatoes either, very susceptible to the fungus. I deal with a fungus that has affected my cukes and tomatoes for many years. The best I hope for is managing the fungus till the crop comes in. Remove the infected plants. They become microscopic spore producers left unchecked. Don't compost the infected plants, fungal spores can survive the composting process. This year I sprayed all the tomato cages with bleach water and replaced all the wood tomato stakes with new. So far, better year controlling the fungus than previous years.
We fight tomato enemies down our way as well. Best I can determine my issue is Southern Bacterial Wilt. The plants take off, look green and lush, put on about tennis ball size fruit, and then just wilt away. Normally one stem branch at a time. Rotation is supposedly the only cure, but I don't have the space at home to rotate, so I grow most of my tomatoes at my Mom's house.
