*BUMP* Hope someone here has personal growing experience and can help. I have never grown any Asian greens - but I probably should.
Bok Choy: Zones 4-7. They are heavy feeders. I learned that with my Brussels Sprouts this season. Dosed them 2x with Blood Meal for the nitrogen and iron...they were 4-5’ tall!

Bok Choy is a cabbage/brassica and the Asian greens I planted are brassica.
Seems like the leafy stuff isn’t quite as hungry as head or thick stalk forming are because mustard is a brassica and did ok here but cauliflower/broccoli, not so much. I really don’t know if it’s pH or N though and didn’t know if someone might have some brassica tips.
