unused jars of tomatoes on garden
Can I dump unused jars of tomatoes on my garden without putting too much acid into the ground. I plan on roto-tilling it under before winter. I have 100-150 jars.
It would probably be ok since you are planning on tilling it all up, though I think adding them to the compost pile might be better. In a compost pile, you would be adding additional items to help balance out all that acidity. You may want to test the soil first should you decide to put them directly into the garden to make sure the area isn't already too acidic, which would not be a good thing. But a soil test would at least let you know what other nutrients, if any, need to be added so you can take care of it at one time.
