WAS Anderson deep propagation flats; Now lowering the water table in pots

I don't use many band pots (the term for the kind of open-based pots 
being discussed here), but when I do, I crumble some oak leaves coarsely 
to put in the bottom, since I don't have screen handy to cut up in 
little squares as done by growers who use band pots a lot. I don't think 
this creates a perched water table in the mix I use, which does not 
contain Perlite, and there are always plenty of oak leaves around here 
(the neighborhood is known as Oak Grove and was originally a Quercus 
garryana savanna plant community, with many of the old oaks still 
around). Any slow-rotting leaves would probably do.
Band pots come in quite a range of sizes, but they are made of rather 
brittle plastic. Growers who need large, sturdy pots with a great deal 
of air circulation might be interested in a kind of larger pot used by 
field nurseries for young trees, which are heavy black plastic with 
large openings all over; they sink these in the soil and root prune 
around them to lift and deliver the trees. I have a few left over from 
tree planting and will use them if I need to grow a big, rather tender 
epiphytic plant that has to be moved indoors in winter. Probably the 
suppliers mentioned here earlier sell these also.
