The water from which the calcium and magnesium sulphate sounds are removed through chemical treatment is known as soft water. They are usable water and used for consumption and also to water your lawn grass. They thus are not the ones for getting rid of the grasses in ones lawn.
If your using salt yes it will kill grass and plants eventually. You can use Potassium instead it's better for you and your plants, it costs more but will still soften your water the same as salt.
No it won't kill it.
no
Yes, hot water can kill leaves, grass, and yard weeds.
If it is a lot of bleach, it will kill the grass.
No, Chuck Norris does.
It may but it won't kill the weeds. It the same way hot water burns you if you get scalded by too hot a water supply from the spigot. Grass seed has a heat limit or it cooks and kills the baby.
The best time is in the early morning. If you water at night the grass could catch a fungus disease. If you water during the day some water gets evaporated so you have to use more water. Early morning is best.
No, by the time it gets deep enough the salt has gone
I cant see how ice would kill grass. as ice is just a solid form of water. which eventu ally melts, which will feed the grass. right?
If sufficiently concentrated, yes. The amount of chlorine in drinking water, however, is not enough to harm your lawn. Even swimming pool water is usually not chlorinated enough to kill grass though normal splashing or draining.
I'm no expert, but if chlorine can kill you, then it can easily kill grass.
