Soil & site
Rich, limed soil, pH 6.5+. A heavy feeder — side-dress with compost midseason.
Seedling care
Transplant at 4–6 weeks, buried to the first leaves. Row cover at transplant stops cabbage worms cold.
Growing notes
The Southern staple for a reason: collards handle both Tennessee summer heat and winter cold better than kale does.
Harvest
Pick lower leaves and let the crown keep producing — a fall planting feeds you clear through winter, sweetest after frost.
