Can you grow Celery on a balcony?
Apium graveolens
Possible, but tricky in pots
Celery (Apium graveolens) can be grown on a balcony in a suitable container. It needs full sun — around 6+ hours of direct sun a day. Up to 140 days to maturity (short-season varieties are quicker); begin harvesting when stalks are about 20cm tall. All figures below are sourced from RHS and the Old Farmer's Almanac.
