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.
Trees and shrubs can be planted in this time frame, as well as flowers whose blossoms you don't plan to eat. Roundup Ready-To-Use Weed and Grass Killer III and Roundup Weed and Grass Killer Concentrate Plus are two formulas that fall into this category. Be sure to wait the entire 24 hours before replanting.ou should wait a minimum of three days, from the time of the last treatment, with either of the products, to plant edible plants like vegetables and herbs or fruit-bearing plants.
