Need help identifying what is killing my plants
stems. I have also observed small black droppings beneath the plant, but have not seen any bugs. The density of the plants is high which prevents getting a good look. I read through a tomato book I have but could not really identify the problem. I will also say the plants are in pots which have peat, vermiculite and the other small glass rock. My home made equivalent of a earthbox.
The plants are on the south side of my house, and get full sun at least 708 hours a day. The house blocks early morning and late afternoon sun this time of year. I would appreciate any tips on slowing or removing this problem, as my tomatoes are big and would love to have a full season worth.
