Answer: A tsunami is a giant wave (or series of waves) created by an undersea earthquake, volcanic eruption or landslide. Tsunamis are often called tidal waves, but this is not an accurate description because tides have little effect on giant tsunami waves.nswer: A tsunami is a giant wave (or series of waves) created by an undersea earthquake, volcanic eruption or landslide.

Roundup is not persistent in the soil. You can lay your sod one week after spraying the weeds. The herbicide will get into the growth of any plant it touches, not anything the chemical does not touch. I don't know of a pre-m herbicide that controls germination of any weeds likely to grow this time of year. Pre-m only prevents weed seeds from germinating.
Roundup is effective on grasses and broadleaf weeds. Donning your armor of long sleeves and pants, safety glasses and plastic gloves, you're ready to do battle with the never-ending weeds in your garden. Wielding your sprayer filled with Roundup (glyphosate), you briskly step outside into the chilly morning air.While you may wonder if it's too cold to spray those weeds, according to the manufacturer the ideal temperature for applying Roundup is between 53 and 77 degrees Fahrenheit.oundup is a nonselective weed killer, usually applied to the foliage of weeds and other unwanted plants. To ensure success, spray the weeds' leaves until they're completely wet, but not dripping.
