Zone 7b specific growing notes
In zone 7b (Atlanta GA, Raleigh NC), your 210-day growing season means kale should be one of your first spring plantings. Cool-season crops thrive in the mild part of your growing window. Monitor soil temperature ā kale germinates best when soil is 40-75Ā°F.
Your first fall frost around Nov 1 means your last possible harvest is roughly late Nov. For a continuous supply, consider succession planting every 2-3 weeks from Mar 15 through mid-season.
Pro tip for kale
Frost converts starches to sugarākale harvested after a light freeze tastes noticeably sweeter. Harvest the oldest outer leaves first and the plant keeps producing from the center for months.
Troubleshooting kale
Cabbage aphids cluster in dense gray colonies inside leaf crevices and growing tips. A strong jet of water knocks most off. For persistent infestations, insecticidal soap or neem oil applied to leaf undersides works well.

Can you plant kale twice a year?
