Dahlia Seeds (Beauty Mix)

Dahlia Beauty Mix is the slow build of this lineup - where zinnia or marigold give you colour inside two months, dahlia asks for patience and more room to reward you with the biggest, most layered blooms in the batch. It suits a gardener who's happy to treat one large pot as a season-long project rather than someone after a quick balcony refresh. Budget space for it: at 30-45 cm apart, this is the widest spacing in the range, so a single deep, wide pot per plant works better than a crowded tray. Germination itself takes 7-14 days, roughly double the wait of a marigold or zinnia, and the plant needs the same full sun window of 5-6 hours daily with watering only once the top soil feels dry. From sowing to bloom runs 90-110 days, and once the stems put on height, stake them - the flower heads get heavy enough to need the support.
