Oops, sorry, I didn't get the photos onto here ( the phone rang and I got distracted).
The photos aren't very good so I uploaded all of them thinking that people's monitors would differ. The first two are the roots of one of the plants, not the worst looking of them, I'm sorry to say.
Do other people put polystyrene into pots for drainage or whatever? I hat the stuff, it's bad enough in the boxes for packing...and I like to have some weight in the bottom of the pot so that they won't tip over as easily.
