Anderson's 5-5-25 Fertilizer with Barricade for pre emergent control of weeds should be applied in late fall when soil temps drop to 70 degrees and continue to drop. In spring time, you want to apply pre emergents when soil temps reach around 50-55 degrees. For the fertilizer aspect, a soil analysis is recommended to determine what nutrients your lawn has or needs going into winter. Typically, the best time to apply winterizer is in late fall, about three weeks before the ground is frozen but for specific timing, we recommend contacting your local cooperative extension office Master Gardener Division for their recommendation on timing and the best NPK value for your turfgrass, nutrients it may need and for your zone.
