Suttons Seeds - Green Manure Winter Mix Transform dormant soil into living fertility. This bold blend of winter-hardy crops captures nitrogen, breaks compacted earth, and builds organic matter while your garden sleeps. Sow in autumn, let it work through the cold months, then dig in come spring for richer, more resilient beds. Skip the synthetic inputs—grow your own soil health. Perfect for gardeners who think beyond the season and refuse to let winter waste precious growing potential.
