What are the pros? Easy -- best to direct sow
What are the cons? None!
If you can grow only one green, choose this one. It's the most versatile and reliable one, no matter the season. No pests, either.
This plant makes it into our family's diet, every single day. The first thing I do upon waking is to stroll out to the garden and pick a thick handful of leaves with which to make green smoothies for the entire family. Not even a hint of bitterness, super tasty and slurped up by everyone. This is the second year I've grown it out, and it will have a home with us always.
