Petunia x hybrida
| 10 Pelleted Seeds |
Trilogy Purple Petunia is smothered in stunning fuchsia trumpet-shaped flowers that begins blooming in mid-spring from an indoor winter sowing, and then keeps going all summer and into fall that is less day length sensitive than other leading spreading petunias, resulting in earlier flowering. Trilogy varieties are perfect candidates for hanging baskets, mixed combo planters and large pots. Trilogy is a spreading petunia series that is creating a buzz with its nicely controlled dome habit that is chock full of flowers. The plants almost smother one another with such a large quanity of large vibrant flowers. Trilogy is rain resistant that will not leave a bare spot in the center of your basket or container. Have a stronger root system then most trailing petunia means for you a better performance in the landscape. Short internodes keep the plants tightly branched and yield prolific flowering Height: 12 to 15", 30to 36" spread.
Tips on How to Grow Petunia from Seeds
Time Frame when plants are receptive to flower initiation: Days 14 – 21; 3 – 4 leaves.
Flowering Type: Long Day Plant – long days required for flowering.
Specific Flowering Mechanism: Flowering is affected by day length, irradiance and temperature.
Germination – Optimum conditions for seedling development that begins the day the crop is sown until cotyledon expansion.
Expect radicle emergence in 3 – 5 days.
Cover: Do not cover the seeds.
Media: • pH: 5.5 – 5.8
Light: Light is necessary for germination. Provide a light source of 10 – 100 foot candles (100 – 1000 lux) if utilizing a chamber.
Temperature: 72° – 76°F (22° – 24°C) until radicle emergence. Gradually reduce to 62° – 65°F (16° – 19°C) as cotyledons expand.
Finish Bulking/Flower Initiation – Optimum conditions during the vegetative period, beginning at transplant, needed for the root to reach the edge of the container; AND to make the plant receptive to flower initiation.
Media: pH: 5.5 – 5.8 Yellow upper leaves may indicate iron deficiencies when pH is > 6.6.
Light: Petunias need long days to flower. To initiate bud under short days, extend day length to 13 hours. Under long day, low light conditions, supplemental lighting of 350 – 500 foot candles (3500 – 5000 lux) may be necessary. Temperature: After transplant, Petunias require temperatures > 55°F (13°C) nights for the first 6 weeks to initiate flower bud development. After bud set, the night temperatures can be lowered to 50°F (10°C) to encourage basal branching and compactness. However, lower temperatures may also substantially decrease the number of flowers initiated. Downward cupping of leaves may indicate too cool temperatures in combination with overwatering. Average Daily Temperature (ADT): 67°F (19°C) Moisture: Alternate between moisture levels wet and dry Allow media to dry before re-saturating to level . Dehumidify: Provide horizontal airflow to aid in drying down the media through evapotranspiration under cool, low light conditions. Fertilizers: Under high light conditions, apply an ammonium-based feed (17-5- 17). Under low light conditions, apply a calcium-based feed (14-4-14). Under high light and long or extended days, an ammonium-based feed (20-10-20) is preferred. To prevent stretching under low light and cool temperatures, reduce ammonium and apply only calcium-based fertilizer.
Light: Full sun
