Planting winter greens may differ depending on your location and brand. Nonetheless, winter greens are ideally best to plant during late summer since it needs enough sunlight before the upcoming cold months. Deer food plot brands have their specific planting dates for every product. When planting winter greens, following the recommended planting dates would be best. An excellent example of this is the Whitetail Institute Winter-Greens. The product has specific planting dates for every corresponding location. Since it is drought resistant, it allows you to plant it from late summer to early fall. Planting it late in the fall will likely produce little results since winter greens need enough sunlight to grow before winter arrives.
