I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
I would avoid the weed and feed products on your lawn. The best weed control is a dense, healthy turf. Do all you can to develop a good, dense turf (regular mowing, deep infrequent watering and moderate fertilizing) and over a year or two you will eliminate the vast majority of weeds in your turf.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
