When to plant Crocus
Crocus is a fall-planted spring bloomer. Plant the corms in fall (Clemson suggests November in the South) before the ground freezes, so roots establish over winter for an early-spring bloom.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
