I noticed a question similar to this re soil that had been used for tomoatoes, but my question is regarding soil that has been used for everything.
This year I have grown all sorts of vegetables, herbs, flowers in containers and everything is now starting to come to an end. What do I do with the soil. Is it safe to dig up the flowers and veg and mix all of the soil to use for next years containers?
Any advice gratefully received.
