WAS Anderson deep propagation flats; Now lowering the water table in pots
Tim Eck (Tue, 20 Oct 2015 15:51:57 PDT)
Fiberglass insulation might work for wicks and hemp is rather rot-proof too.
I used to put my crinums on shelves in the basement and run paper towels out
the drain holes to dry them off for the winter.
Now I dry off my crinums for the winter by putting them under plastic and
planting winter wheat or ryegrass in them (and then hit them with Poast or
Arrow herbicides in the spring to kill the grasses).
By the way, fiberglass insulation is not a bad way to separate a fine
aggregate from a coarse aggregate in a bed. I have seen a lot of bed
designs which were far less porous than the designer thought because they
placed finer aggregates on top of coarser ones, resulting in a bed far less
permeable than either one alone.

Rimmer, I was just today trying to figure out how to drain a low spot in a
raised bed I built. The base of the box has chicken wire to keep out the
rodents & the ground has landscape cloth then 2 layers of black plastic to
keep out the mulberry tree roots. Mulberry tree providing essential shade
but roots are terribly invasive, so I don't want to put a hole in the
plastic. Now
I can try to put in some wicks to do the job! Thank you, sometimes the
obvious is everything but. Any suggestions for large scale wicks would be
appreciated.....my 'box' is 8' x 4' x 8".

i heard at a bonsai show lecture, (method also used by Streptocarpus
growers )
that if you put a piece of yarn in the pot extending down you not only
keep
the pot media moist by adding a wick to soak up water from below, but it
also lowers the water table in the pot.
think- hydro communication with the media below.
they recommend a yarn that does not rot, so not cotton but Orlon or some
other synthetic yard.

Putting screen in the bottom, which is, of course, the only way to
prevent
the growing medium (in my case, perlite) from falling out, will still
create a
perched water table, but hopefully far enough down in the deep pots to
prevent root rot.
