Questions about cabbages
When to plant cabbages?
In zone 8: plant out from April to June and in August. The four other zones are in the calendar above; at altitude or after a long winter, aim for the end of the window.
How long until harvest?
About 100 days after planting in zone 8, then the harvest lasts about 30 days.
How far apart?
50 cm between plants along the row and 50 cm between rows.
Can you grow cabbages in a pot?
Open ground is better: the crop needs room and depth that a pot does not give.
What to plant nearby?
Good companions: dwarf bean, celery, lettuce, mint, potato, rosemary and thyme. Keep apart: strawberry and tomato.
