Hi all. Hope someone can shed a little light on this tomatofruit I found today. There was one other like it. This plant has many other healthy fruit on it, but I’m wondering if I should be concerned. It’s on the side, not the stem or blossom end. The tomato doesn’t stink or feel weird, and the bad patch is almost leathery.
My hypothesis is damage of some kind that the plant managed to heal.
Clay, shade, neighbor’s Norway maples.....we’ll work it out.
That's anthracnose. It's caused by a fungus, and likes hot, humid conditions. I've found it more problematic in my gardens when tomato plants are planted too close together which limits air flow through the plants. Tomato plants transpire a lot of water and good air flow from breezes can really help keep things from getting too moist.
