About Collard Greens
Collard greens are a Southern staple — extremely hardy, tolerating both frost and summer heat better than most brassicas. Rich in nutrients and one of the most productive greens per square foot.
Start indoors 4-6 weeks before last frost or direct sow. Harvest lower leaves as needed. Plants withstand hard frosts — flavor improves after cold snaps. In warm zones, grow as a fall/winter crop.
