Re: [APD] holes in new sword leaves

[Dave Wilson <aqua_green at bigpond.com>]

Hello Stuart,
I buy potassium bicarbonate from and Agricultural Supplies business here
called "Barnyard Trading" just outside Darwin in the NT.   It comes in 25kg
bag for about $7.50 a kilo.   They also supply other agricultural chemical
fertilisers and chelated trace elements, all the nice chemicals people talk
about here on this list.

You should try outside the city in a rural area where there is a
horticultural industry (fruit trees or vegetable growing business).
Perhaps a hydroponics supply outlet may also be able to get some.   I pay
$7.50 Australian a kilo as opposed to about $1 a kilo for bicarb soda.  If
you really get stuck I could mail you some but postage costs would be
enormous.

Hope this helps a little.

Cheers
Dave
