I had always snobbishly regarded potting soil as something marketed to apartment dwellers or people who didn't understand gardening.
Now have to re-evaluate.
I made a rectangular planter in wood shop years ago. About twice the size of the redwood planters sold in stores. Today gardener helped me get it back on wheels (from which a (*&^%#%&* person had removed it -- don't ask!!). Very heavy.
He said it was because I was using ordinary garden soil; said potting soil would be much lighter. Said it would work just as well.
QUESTIONS: a. Is potting soil just as good as garden soil (assuming garden soil is OK)?
b. Is it worth replacing x% of garden soil with potting?
c. Or remove and replace all?
d. Leave it alone.
I am NOT looking for work!!! Planter is back on wheels and can be moved, with some difficulty. For now, just asking if anyone agrees with gardener's opinion re: potting soil vs garden.
