Like other gardeners I forgot to add micronutrients and had a zinc deficiency on my squash and cantaloupes. This was a major disaster in my cantaloupes because they got a fungal disease and only produced a few fruit before they crashed.
This in contrast to previous years when I had amazing success and five pound fruit.
I am definitely on task with mineralizing my soil again and might talk about this and compost in October.
The good news with the zucchini is they bounced back and started growing fresh green leaves again late in the season so I will get a second chance.
