STARTING YOUR SEEDS
Sow indoors from fall until mid-February, spacing 25 cm apart. Cover the seed lightly with vermiculite and maintain high humidity. Keep the room temperatures at 15-18°C. Germination takes about 3 weeks.
When 5-6 leaves open, you can start to introduce them to cooler temperatures (13-15°C). After a few more weeks, you can transplant them into bigger pots or directly in the flower beds. Do not allow the plants to dry out in order to prevent tip burn.
Support is recommended to avoid damage to plants during windy periods; especially for single-stem production.
