Scientific Name: Petunia nana compacta

Origin

Petunias are native to South America.

When To Sow

In cold climates sow petunia seeds from mid-Spring to late Summer.  In temperate climates sow petunia seeds from early Spring to late Summer.  In subtropical climates sow petunia seeds from early Spring to mid-Summer.  In tropical climates sow petunia seeds during the dry season from late Autumn to early Spring.

How To Sow

Petunia seeds require light to germinate.  Sprinkle the seeds over damp growing mix and cover with only a light sprinkling of mix, then press down gently to ensure good contact between the seeds and the damp growing mix.  Water regularly to ensure the fine seeds don't dry out as they are trying to germinate.  Prick out and pot up individual seedlings as soon as they are large enough to safely handle.

Germination Time

Petunia seeds take 10 to 15 days to germinate after sowing.

Growing Tips

When planting out space petunia seedlings 20cm apart, they will form a continuous matt of flowering colour as they grow.  Petunia will flower best when grown in a full sun aspect, but can also be grown in light shade.  Fertilise regularly for best results.  Can be grown in pots.

Time To Flowering

Petunias will take 12 to 14 weeks to begin flowering.
