Step-by-Step Guide to Sowing Platycodon English Bell Flower Seeds

Indoor Sowing

1. Prepare Containers: Use pots or seed trays filled with fine, well-draining seed compost.
2. Sowing the Seeds: Scatter seeds across the compost surface and press them lightly into the soil without fully covering them. The seeds need light to germinate.
3. Temperature: Maintain temperatures between 12–20°C (54–68°F) for successful germination.
4. Moisture: Mist the soil gently to keep it moist but not waterlogged.
5. Light Requirements: Place containers in a bright, sunny location such as a windowsill or greenhouse.
6. Germination Period: Expect seeds to germinate within 7–14 days under optimal conditions.

Outdoor Sowing

1. Soil Preparation: Choose a sunny, well-drained spot in your garden. Loosen the soil and remove weeds or debris.
2. Sowing Depth: Press seeds gently into the soil surface, leaving them partially exposed to light.
3. Watering: Water lightly to settle the seeds and keep the soil moist throughout the germination period.
4. Spacing: Once seedlings appear, thin them to a spacing of 10–15 cm (4–6 inches) apart.

Caring for Platycodon English Bell Flower Plants
