Where to buy Sucker Stopper
 

I think it was on this forum some time back that there was a discussion
about stopping tree roots from sending up shoots by applying a product
called
Sucker Stopper. I am wondering if anyone has seen it for sale at any place
other than Red Barn? (The store near me is out of stock and neither Home
Depot nor Lowes carry it.)

I'm looking for the 8 or 22 oz spray bottle ($10 & $25.00) rather than the
quart of concentrate ($100+).

Thanks,
TR
