As mentioned in a previous post earlier this year, we are using cattle panels as tomato trellises. I am happy to report they have done a phenomenal job at supporting the tomatoes, providing adequate airflow, and making weeding a quick chore with the weed wacker. Our rows are seven feet wide which sounds kind of ridiculous, but this distance has really kept the plants from getting tangled together, and we can walk down the rows without brushing leaves and releasing blight spores. The tomatoes are showing some blight, but it is very minimal this year despite being a wet year.
This year we also used old t-shirts as tie-backs for the tomato stems. The t-shirts work well in the tomato patch because they don't cut into the stems like twine and rope do.
