Growing directions
Sow seeds vertically, pointed end down, barely covered, as they are sensitive to orientation; maintain 70–75°F for germination. Plant so the crown sits slightly above soil level to prevent crown rot, which is the most common cause of plant failure. Water at the base rather than overhead; gerberas prefer a dry-wet-dry cycle rather than constantly moist soil. Deadhead spent flowers by cutting the stem to the base to encourage continuous bloom from spring through fall in mild climates.
Source and local conditions
Typical planning ranges from OpenPlantDB (CC0). Cultivar, climate, season and growing method can change these values. Confirm the seed label and local guidance before planting.
