When Should I Apply a Winter Fertilizer to My Lawn?
When should I apply a winter fertilizer to my lawn?
Winter fertilizers are usually applied in late October or early November to cool-season lawns. To take full advantage of the effects of winterizer fertilizer, you should also apply fertilizer to your lawn in early September. The early fall feeding stimulates root growth.
If you plan to make only one fertilizer application in fall, the best time is late September or early October.
