grow carrots in a large container filled with soil which has been finely riddled and mixed with sharp sand, could I reuse that soil to carrots again or would I need to empty it out and start again?? or even change just some of the soil?
It was hard work but I decided to do it this way instead of straight in the plot, i'm hoping going to be able to use it again but have a feeling i'm going to be told differentley.
Thanks
