Vinegar for weeds

To Leo Martin, You know as well as I that if you have enough money and the  
right connections (say through a Botanic Garden) there is no plant that is  
unobtainable. It may be hard to find but depending on a person's. cash  
outlay anything can be bought. I know of a case where a gardener had a huge pot 
 of peyote cactus. He was not a member of the Native American Church ( 
which can  possess this plant), it is a Federal Crime to grow and yet there it 
was. I would  consider the grower quite talented and the huge clump was grow 
to perfection.  This proves that under the right conditions you can get 
anything. I should  add, because this cactus is being rapidly destroyed I think 
the grower was  doing a good service helping to preserve this plant. If you 
don't care to give  or sell plant material why don't you consider sending 
members to sources so they  can get something they want. I really feel that 
the members are not gullible.  They are just looking for a source for some 
hard to find plant. By the way my  huge variegated Cycas revoluta, I think the 
parent was from Okinawa,is doing  very well in our growing conditions in 
Phoenix,trunk about 6 inches thick. Now  this is rather rare but it is possible 
to find a seller-Russ

With  grasses I would think the idea would be the younger the better so they
have  not had time to develop a large root base - which takes more vinegar.
In  dealing with Whitetop, the extension agent said if one is going to  
they need to time the spraying to when the plant is winding down for  the
season and is taking food stores back down to the roots .   Otherwise all 
would be doing was burning the tops.  Yes that could  serve to set the plant
back and enough of it might kill the plant, but it  wouldn't happen 
So, this line of thinking appears to agree with  what you were taught.  It
does make sense.  The risk I see is  that if you are a bit too late with the
herbicide, you have allowed for  another year's seed set, which is what 
to happen with this method and  Whitetop.

Dell  writes that his vinegar potion only kills the tops of  undesired

On this, long ago in  our
"Kill-raspberries-et-al.-that-competes-against-spruce-&-fir" course  in
Forest Management @ UNB, Canada, we were instilled with the notion  that
"weeds" are best dealt with near the end of the growing season when  they
have used up all their resources.

Perhaps timing is a concern  here.
