Can you grow Geranium on a balcony?
Pelargonium
Yes — great in containers
Geranium (Pelargonium) grows well on a balcony in a pot of at least 10 litres (about 30 cm deep). It needs full sun — around 5+ hours of direct sun a day. Flowers through summer until first autumn frost (ornamental, not a food crop). All figures below are sourced from RHS and the Old Farmer's Almanac.
