Growing Information
|
How to plant:
Propagate by
seed
- Balsam is a prolific self-sower. After one season of growth, it generally reappears from self sown seeds the next year. After frost has passed, scatter seeds where desired, or sow seeds indoors 6 to 8 weeks before the last spring frost. Do not cover the seeds with soil, as they need light to germinate. Until the seeds germinate, cover the seed trays with clear plastic to maintain high humidity. Water from below to prevent damping off.
Germination temperature: 65 F to 70 F
Days to emergence: 7 to 14
Maintenance and care:
May be a weedy nuisance due to its self seeding habits. Keep soil moist but not soggy.
