Yes, not my day to post, but I just received an email with a link to a new product called Packing Pearls. These are polystyrene balls that fill the bottom of large containers so they aren’t so heavy. They are promoted as “improving water drainage and oxygen flow.” You can find a link here
The “pearls” are separated from the soil and plant roots with a pot liner (composition unknown). We’re told that the roots can’t grow through the pot liner. So now my question: can a material that “improves water drainage and oxygen flow” be impervious to root growth? Doesn’t it sound as though you’d be waterlogging the soil by installing this liner?
I honestly don’t know the answers to these questions, and the web site is not detailed (nor does it contain any links to research). The emailed advertisement states “Tests show that flowering plants bloom two to three months longer when grown in containers with a base of Packing Pearls. Plants are also visibly healthier and hardier.”
Anyone used this system before?
