I am going to be transplanting some chard and kale seedlings. The mature size of different types vary widely yet I read broad generalizations like plant 8 inches or 18 inches apart.

These are the varieties I will be planting.

What spacing would you recommended?

I will be doing cut-and-come-again and this will be a slightly shaded area.

Swiss Chard

Perpetual Spinach

Bionda di Lyon

Verde de Taglio

Barese

Five Color Silverbeet (Baker Creek)

Oriole (Baker Creek)

Kale

Dazzling Blue

Red Russian

Thank you so much!
