In general, we would recommend killing the undesirable plants and clearing out the dead plant debris before dethatching and then reseeding the lawn. Dethatching will be easier and you will get better germination with your new seed when the ground is better prepared for it. You can learn more about these treatments in our Do My Own Lawncare Video Series, too. You can find them on the bottom of our Lawn Care Guides page here.
Tenacity will keep for 3-5 years from the date of purchase if stored away from extreme temperatures. If yours was purchased in 2013 it may still be good. You may wish to contact the manufacturer directly to see what they recommend. You can reach Syngenta by calling 800-334-9481.
