I planted two gardens both about 70x100 each. I had the soil tested and it came back good just had to add 3lbs N per 1000 sqft. The problem is everything starts great and when it gets close to harvest it rots or busts. The only thing that does good is the zuchini and squash. tomatoes,canalope and cucumbers rot quickly. I pulled some tomatoes and let them ripen in the house and they had a bitter tate to them. I thought it might be some kind of fungus but I don't know. Any Ideas?
