This does not seem like the time of year to spray for dandelions. You do not see them now! But September is the best time to spray for dandelions. This is when dandelions are moving carbohydrates down into the roots for winter. So they also take weed killer down into the deep roots. The best time to take care of many problems is long before they become obvious. Bishop Rosie O’Neal says “Procrastination is the arrogant assumption that God will give you another chance in the future to do something he called you to do today.”
