From seed to a productive flower display
Planting
Surface sow warm and grow seedlings brightly.
Start early because the seedlings are tiny. Warmth, light, and prompt potting-on create sturdy transplants for the outdoor season.
Press seed onto the surface
Use fine moist mix and do not cover; a clear dome can help hold humidity.
Remove the cover after emergence
Give bright light and gentle airflow, then pot on when seedlings are easy to handle.
Wait for warm nights
Harden carefully and transplant after frost when nighttime temperatures remain mild.
Ongoing care
Keep plants healthy and flowers productive
Balance light and leaf color
Morning sun or bright filtered light suits most varieties; protect leaves from harsh afternoon scorch.
Water before wilting
Containers and established beds perform best with consistent moisture and good drainage.
Pinch growing tips
Pinch young tips and later soft shoots to encourage a dense branching habit.
Remove flower spikes if desired
Snip spikes to keep attention on foliage and prolong compact growth.
