I took these pictures after clearing blighted branches as best as possible. The blight hit each of the 12 tomato plants. This is a note to future Mark when he reads this next July, the moment you see what looks like blight pull the entire plant and get it off the roof.
Container 2 is the left most container. It’s a Celebrity brand tomato and it suffered 1/2 loss. Container 3 is some heirloom from Gesethemane and it was one of the first to develop symptoms. It is completely gone. I should have pulled this plant without mercy a week ago. Note to future Mark, no heirloom tomatoes. Container 4 is a Brandywine and doing OK — about 1/4 loss. Containers 5 and 6 are Early Girls. Tomatoes are small about 1/3 loss to blight so far. Leaves yellowing and little second growth. Note to future Mark, don’t plant Early Girls next year.
This picture shows containers 8 through 12. Container 8 is left most container. It supports an Early Girl that lost 1/2 its branches to blight. Container 9, a Brandywine, was a complete loss. Container 10 is a Celbrity, 1/3 loss but good second growth. Container 11, first container off the rails, is a Celbrity and almost (will be) a complete loss. This was a weak plant from the beginning. Note to future Mark, do not let weak plants grow. Pull them and replace them.
Theory: The risk of blight increases with weaker plants of any variety and the introduction of unknown heirloom varieties.
Container 12 is in a smaller container and I think it’s a Celebrity or Early Girl. Its prognosis is grim. Container 7 (not seen) is doing OK. Container 1 (not seen) is like Container 12 but in better condition. Both containers 1 and 12 used smaller pots as experiments.
