Beat tomato blight.
I read through my February/March 2015 issue of Mother Earth News with great interest, particularly the article "ID and Prevent 6 Common Tomato Diseases." I have a recipe to prevent early blight that I got from an old farmer in North Clarendon, Vt., and it has been working well for me for years.
Before transplanting, mix: 3 cups compost 1/2 cup powdered, nonfat milk 1/2 cup Epsom salts 1 tbsp baking soda
Sprinkle a handful of the mixture into each tomato's planting hole. Then, after planting, sprinkle a little more powered milk on top of the soil around the plant, repeating once a month throughout the growing season. This will also help prevent late blight and certain other tomato diseases.

Using large amounts of Epsom salts (magnesium sulfate) can be helpful or harmful, depending on your soil's mineral levels and pH. It's a good idea to have your soil tested before applying any soluble minerals (such as Epsom salts) in your garden.--Mother
