How to Grow Rudbeckia ‘Sahara’ from Seed
Sowing Rudbeckia Seeds
- Start seeds indoors March–April for earlier flowering
- Sow into modules or a seed tray and cover lightly with compost
- Keep warm at 18–21°C until germination
- Prick out / pot on once seedlings have true leaves
- Harden off for 7–10 days before planting out after the last frosts
Planting Out & Spacing
- Plant out May–June once nights are reliably mild
- Space 30–40cm apart for airflow and straight stems
- Choose full sun and reasonably fertile, free-draining soil
Growing On
- Water to establish, then water deeply only during dry spells
- Pinch out the growing tip when young (optional) to encourage branching
- Stake only if your site is exposed — most plants stand well if spaced correctly
- Deadhead regularly to keep flowers coming
Aftercare
- Feed lightly every 2–3 weeks in summer (especially in containers)
