Your personal fluid requirements also can vary each day, depending on the other things you're doing, eating, and drinking. The Institute of Medicine recommends that women get 2.7 litersâthatâs 11 cupsâof water per day. Note, they donât say you need to drink 11 cups of water a day. That includes all sources of waterâfrom a basic glass of tap, to a cup of coffee, to the water content of the foods you eat (which, the IOM estimates, makes up about one-fifth of your daily fluid intake).
Roundup will work in the winter, it just takes longer. On a summers day it will start to kill weeds within 2-3 hours, with visible signs in within 4-5 days it takes 6 or more hours in the winter.

The weed needs to be actively growing in order for the herbicide to be absorbed.t 35 deg. there is very little growth in most plants and thus very little herbicide absorption. Wait until a warm day, when the weed is actively growing and the effectiveness will be greatly improved. Roundup has no soil activity, so it does not work on weeds that have not already germinated and are actively growing.
