What am I doing wrong?

Asked August 17, 2019, 8:54 PM EDT

I plant my pickle plants on a trellis, my tomato plants separate from each other. I started to spray fungicide on them when they started showing something was wrong. I water every day. Is it me doing something wrong, or is it the weather.? I look @ my brother’s plants & his pickles are just full of them. He also has his tomato plants growing together close & doesn’t have to spray anything. He lives down the street.

Fungicide application is most effective before or just as a plant shows symptoms, as fungicides cannot cure a plant from disease. Many fungal diseases are airborne, meaning that transmission can be haphazard. When applying fungicide, it's also important to read the label. Fungicide application when it's too hot can damage plants. A few additional resources on fungicides in tomatoes: https://njaes.rutgers.edu/fs547/

It's hard to diagnose what is wrong with the cucumbers. It's not powdery mildew. Again, if the cause is a disease, transmission can be random. Your plants could be affected but the cucumbers down the block may be doing well. Overfertilizing could be another cause. Overfertilized cucumbers have excellent vine growth but produce few fruits. Finally, your cucumbers may have received inadequate pollination.
