Sun requirement for kale: Plant in Full Sun
Kale is a cultivar of the species Brassica oleracea. It has green or purple leaves that branch off from one to multiple upright stems and do not form a head like cabbage. The plant is usually grown as an annual, but if grown as a perennial, it will form seeds in the second year. Current popular varieties include Curly kale, Italian kale, and Red Russian kale (green leaves with pale purple stems). It can be grown as baby salad greens or for bunching adult leaves. Leaves are sweeter after a frost and delicious eaten raw, added to salads, sautéed, or added to stews and casseroles.

Getting ready for spring!
by maco,
I've got seeds either on-hand or ordered for just about everything I'm starting from seed this year. I've been working out what I want to plant, and this is the plan I've come up with for the 72 square feet of my backyard raised beds:
 |
| Optimal soil texture | heavy, medium, light, organic |
| Optimal soil fertility | high |
| Optimal soil drainage | well (dry spells) |
| Optimal soil salinity | low (<4 dS/m) |
| Photoperiod | short day (<12 hours), neutral day (12-14 hours), long day (>14 hours) |
| Optimal light | clear skies |
