Per the product label, Ferti-Lome Winterizer and Weed Preventer II 10 - 0 -14 can be applied in the early fall, in August and up to November but that depends on soil temperatures and when you're expecting the first frost. In the north, typically between August and September is best, especially because this product is also a pre-emergent, but we do also recommend checking with your local extension office for the best time to make an application.
