 Over on my daylily list there is a discussion about using copper
 infused felt bags

Copper is very toxic to plant roots and one can buy copper paint and paint
landscaping fabric.  When the roots hit the painted fabric with the copper
the ends die.

In the tree business many pots are painted with a copper compound that makes
the root systems branch out more.

Even container grown perennials are some times planted in copper treated pots
to give a more balanced root system.

Paul,
You have hit what was bothering me square on the head. I understand the rational for the pots, avoids root bound plants/trees, BUT
what about the plant that is on the inside of the copper felt bag - eventually the plant will run out of room. I thinking of hostas that can have huge root systems; wouldn't the plant eventually weaken and die?
