Petunia Blue Star Sowing in seed trays

Petunia Blue Star Sow your Wave petunia seed into a moistened germination media or potting soil. Petunias benefit from light for best germination, therefore do not cover the seeds. Place the tray in a warm and bright location.

Fluorescent lights are suitable for a light source, both for germination and for growing on. Place the fluorescent light approximately 3-6 inches (7-15 cm) above the top of the tray. The lights can remain on for 14-16 hours per day. A timer may be helpful to turn on/off the lights. And though light is important, you don’t want to place the tray in direct sunlight.

For tray temperature, you’re looking for 70-75 degrees F (21-23 degrees C) at the soil level for optimum germination.

The seed tray should be kept moist, not soaking wet or dry. Misting the tray with a clean spray bottle is the best method to water in this early stage, as this does not disturb the seed. Check your tray daily and water when the soil looks dry on top and the trays feel light. Do not allow the tray to completely dry out. Here’s a quick tip: Covering the tray with clear plastic may help maintain temperature and increase humidity.

After germination

Once germination occurs and small green leaves (called cotyledons) are visible, remove the plastic cover. These early first leaves emerge in about 5-12 days.

Keep your tray in the bright or fluorescent-lit area. The temperatures can start to cool, ranging from 65-70 degrees F (18-21 degrees C). Night temperatures can go down to 55 degrees F (12 degrees C).

As the plants grow, and if you’re using fluorescent lights, move the light fixture up to maintain the 3-6 in. (7-15 cm) distance from top of plants. Once the young plants have between 4-6 sets of “true” leaves, it’s time to transplant them to individual pots or packs.
