Answer 1

Generally when you fertilize with a weed killer you want to do it int the morning when the dew is on the grass so that the weed killer sticks to the leaves of the weeds as that contact is what kills the weeds.  Otherwise you lightly watter prior to spreading and then don't water for 12 to 24 hours for the effect to be greatest.With watering after spreading you may have lessened the effect of the weed killer but everything will green up pretty fast and you will have to mow more often.

Answer 2

Watering about 30 minutes is correct..however..do not water at night you are inviting a fungis to kill your grass from it standing all night..Water early in the morning  

Answer 3

30 secs???? do you mean mins?? 30 secs won't even begin to melt the pellets!! Water at least 30 mins to melt it and get it down into the root zone.When to water it again depends on how hot your weather is,and how soon the ground begins to dry up.In hot weather water every night for 15-30 mins.The grass should start greening up in about a week.
