Normally, mid-May into mid-June are the weeks where you grab a tall, cool glass of Kombucha and sit down in your comfy deck chair and watch things grow…normally.

My garden in the mist
This year, 2018, what I am frequently doing is sighing, drying off my dogs and hoping that the cold (low 50’s right now), wet weather doesn’t finish off all the plants I raised from seed.
This is my garden, in the mist. It looks pretty good, from a distance.
But my tomato plants are really starting to show the wear of 4 weeks of wet weather. The yellowing and spotting on the leaves is spreading and, because of the persistent wet growing conditions, I don’t think I will be able to stop the destruction.
What my tomatoes have is called Septoria Leaf Spot.

Septoria on my tomato babies.
Septoria is a fungal disease. In normal weather conditions, you can usually prevent or at least slow it down by following good gardening practices like:
- removing diseased leaves quickly
- watering with soaker hoses,
- never watering at night,
- spacing your plants so each one catches the breezes and dries out,
- rotating where you put tomato plants from year to year.
But I’m not experiencing normal weather conditions. And this fungal disease loves it when it’s wet out.
According to Michigan State University Extension (MSUE), my back yard is the perfect storm for Septoria, “When conditions are wet, spores are exuded from the Septoria fruiting bodies present on the infected tomato leaves. Once the spores land on a healthy leaf, spotting can appear in five days if weather conditions are ideal.”

Septoria will affect 2019 garden, too
Worse than experiencing Septoria, this year, is the fact that the spores shed by the fungus live on in the ground cover and even in the soil. So, even if I remove the infected foliage, even if I rotate my plants, the chances of recurrence in 2019 are high.
I certainly have ideal conditions for this fungal invader!
I will fight back this year by using an organic fungicide called Serenade. I don’t like resorting to this solution but it is non-toxic to birds, bees, beneficial insects, fish, and wildlife.
As an organic gardener, I hate introducing this into my eco-system but I know the long-term damage Septoria can cause and I have to take necessary measures to reduce or eliminate this “perennial” from my garden.
And I will soldier on with the rest of my plants because that’s what gardeners do and because there are other plants growing quietly, albeit slowly, in my garden that need tending to. Here are some photos of these brave, green soldiers.
