|What is the amount of light needed to germinate Petunia and Geranium seeds?
|Petunia and geranium seeds will germinate without light. Just sow them in flats of potting mix, cover with plastic, and put them in a warm place for 10-14 days (or until they've sprouted). Then remove the plastic and place them in a brightly lit area. Geranium seeds prefer heat (70F) when germinating, but petunia's don't have a heat requirement.|
