Description : How can I repair the soil after having tomato blight?
Last Answer : I would mix that soil with very old horsemanure, lime, mulch, hay, grass & leaves and turn it in. PH for tomatoes is 5.5-7.5 If blight happens again, take the whole plant out and bag & ... plants and bagged & trashed them. Please do not mulch these as you will keep the blight in your garden.
