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 potting soil vs garden.
