Hello Peter,i have a small Garden at my home with Tomato Plants. It seems as though my plants have started to get Septoria leaf Spot. It is starting to work its way up the plants. I always water from the bottom of the plants to avoid wetting the leafs. Are there any organic products I can get to slow this process down. Thank you Dave
You are not alone. The weather this summer has been wetting the leaves plenty. You can treat with copper or sulfur fungicides and that will the leaf spot from spreading but won’t cure the leaves already damaged…they should be cut off and disposed of into the trash…not the compost bin. Pruning away some of the leaves will also improve air movement through the plant helping it dry more quickly and keeping it a bit healthier. Don’t plant tomatoes in that spot for a couple of years.
