Growing Mixed Double Trailing Petunias from Seed
- From January onwards sow either indoors, or outdoors, heated undercover at 21-27C (70-80F)
- Sow petunia seeds on the surface of a good fine seed compost; gently firming down. Ensure not to cover them fully, as the small seeds need light to germinate.
- For better handling, add some horticultural sand into the provided bag. Seeds can then be poured out easier.
- Keeping the soil moist, not wet, seal in a polythene bag or cling film after sowing to retain moisture.
- Light is needed for successful germination which usually takes between 10-21 days.
- When seedlings large enough to handle, transport into trays and continue to grow in cooler conditions before gradually acclimatizing to outdoor conditions once the last frost has passed.
