How to grow Petunias from Seeds

The Petunia bloom throughout the summer and most of its varieties prefer to be grown in full sun.  During the peak summer, it is better to grow them in partial shade.  Normally, a petunia plant starts to exist from a seed within 10 to 12 days from planting the seeds.  Adequate sunlight and moisture is required for the seeds to germinate.  If starting the seeds early, it is ideal to germinate the seeds indoors in a warm place using bottom heat more than 25C, no more than 27C.

To grow the seeds, all is needed is to sprinkle the seed to the soil surface. Sow the seeds on top of moist soil.  Use sterile seed raising mix to germinate the seeds because potting mix can burn young seedlings.

Pat the seeds lightly or press the seeds gently using a small wooden block of wood.  It is important not to cover the seeds with soil but cover the seeds with a sheet of clear glass or plastic wrap once they are sown.

Petunia seeds must have light to germinate.  When the seeds show signs of germination, remove the covering off the seeds and move the seeds to warmer areas.

If planting outdoors, then you must wait till the cooler temperatures and frost are over as the petunia seedlings are not frost resistant.

Keep the seedlings moist, using a fine misting bottle, at the same time fertilising the seedlings with half strength fertiliser solution.

Pinching the seedling back when planting, will encourage more branches and this means more flowers.  Petunias will thrive in moist rich soil, but do not like over wet soil, so water the plant carefully.  They will not tolerate dry periods for a long length of time.
