I am trying to kill killinga in my lawn with salt. I have had limited success with it but have not totally killed off the plant. it seems to set it back but does not kill it completely. I have used salt, with no ill effect, on seashore paspalum for clover and other weeds that are not conducive to pulling, but due to the succulent nature of the killinga I think that it will take a mega dose of salt to kill it. I'm afraid that I will permanently destroy the soil by using such a large dose salt on the area. is there any way, besides manage, to kill off killinga?
