Question
there is a lot of moss on the tree stump and branches.kindly let me know what i should apply to kill it

Answer
Vcsrajan:

Moss occurs frequently in environments that are consistently moist or wet.  Consider methods to allow these surfaces to dry- which will in turn discourage moss.  Check out the web for several products sold that can be sprayed directly on the moss.  I have not had experience with any products, so shop carefully.

Thanks
