Apply the herbicide meant for Sissoo tree root removal into the holes. And let the tissue transport the solution to the roots and sprouts. So, avoid digging out the stump a few days after spraying the solution. 

Step 3: Treat the Sissoo Tree Sprouts Around

Some sprouts grow too far from the stump that the solution hardly transfers to them. In that case, spot those sprouts and dig a larger surface around them to chase and expose roots near or under them.

Then, spray the herbicide on the greens and expose the Sissoo roots. In a month or so, it will weaken and kill the root growth. Avoid pulling out the little sprouts otherwise, the conduction process will hamper.
