Q.Leaf spot on tomatoes

Zone NE Ohio | Jim Fischer added on October 12, 2019 | Answered

This past season I planted mostly heirloom tomatoes I grew from seed in my small garden and I was infected severely with septoria leaf spot.
I sprayed somewhat slowed down the septoria and cleaned up all infected leaves this fall.
My concern of course is having septoria return next season and with small garden I don not have the luxury of rotating my crops.
What might I do to prevent the return of septoria to my tomatos next season?

The best thing to do here will be to clean up ALL debris in the area. Dispose of it away from the site, and let it sit for a whole year before planting again. You will also want to treat it with a fungicide at the start of the waiting period.

since you don't have a way to rotate your crops, the empty waiting period will simulate this.
