How to eliminate the roots of brush at waterline within a pond? I have a two acre pond surrounded by the northeast and on...

I have a two acre pond surrounded by the northeast and on the waterline on the dam is a obstinate bush/brush species( oval leaves, has a small sphere (ball) for a flower that almost looks like a pincushion)........ due to concluding years rain , at this point the stumps are above the waterline(I've be cutting them back)

these stumps are exceptionally established so digging them out is not possible, Is here something to put on these stumps to kill the roots(round-up?) (salt?)....(burning them?) If it rain at some point the stumps will be underwater..........help

Answers:    That's tricky - you don't want to poison the pond - means of access too many transparent things in near.

I recommend (even without the pond issue), using concentrated Brush-B-Gon or other Brush assassin - UNdiluted. Make a fresh cut on the stumps, cut any new sprouts, and next very painstakingly, paint the cut surfaces using a small paint brush.

You might have to do this 2-3 times the first year, and later maybe once a year for a couple years - but it will evenutally dispense up and stop trying to re-grow itself.

Use round up. It is actually thoroughly safe. I doubt it will work until spring and the sap starts running. You will enjoy to keep applying it several months, but it should kill in cold blood them eventually.
