I don't remember where I got the idea to use packing peanuts in the bottom of plant pots. Thinking my bucket would be lighter to move to a new house, Variegatta di Bologna got it's start as a band in a fairly large bucket with packing peanuts in the bottom.

It's almost August, haven't moved yet, and all VdB leaves were turning yellow. Turned it out of the pot and the roots were an abominable tangled mess around the peanuts that I had to break off.

The peanuts may work well temporarily for other plants, but It was a nutty idea for roses.
