I've just come back from a week in the US and was buying plants in pots at at GC (as you do ;D).....
Apart from the larger plants in 1 gal. containers, and therefore in the standard rigid non-recycleable plastic pots we know, anything under that was sold in what was to me a 'jiffy' pot which had only a thin plastic collar on which was printed the plant name, growing instructions, etc.....and THAT collar was made of 'degradeable material'.(according to the blurb)....?
I was SO impressed..
But is this news? Are UK retailers doing the same? I'd love to know, cheers!
