Fertilome Weed Free Zone is not labeled for eradicating sandspur. You should apply Barricade as a pre-emergent (check with your Master Gardener at your local cooperative extension office for correct timing). Hi-Yield 2, 4-D Selective Weed Killer can be applied to established lawns for post emergent applicaton. Please refer to the product label for instructions on mixing and application.
