What you need to know to Plant & Grow
‘Goldsturm’ is a robust perennial that can be started indoors in early spring or sown directly outdoors in the fall for natural winter stratification.
-
Outdoor Fall Sowing (Recommended): Direct sow seeds outdoors in September or October in a sunny location. Allowing the seeds to naturally stratify over the winter breaks seed dormancy for strong spring emergence.
-
Indoor Sowing:
-
Start seeds indoors in a quality soilless starter mix from February to early March.
-
Maintain a temperature of 20°C during the 14 to 21 day germination window.
-
Once sprouted, grow on under lights at slightly cooler temperatures.
-
Harden off seedlings and transplant outdoors after frost danger passes.
-
-
Spacing & Care: Space plants 30 cm apart in full sun. Avoid rich, high-fertility soils, as overly lush growth can weaken flower stems. Water at ground level to keep foliage dry and promote plant health.
