General Growing Tips For Your Unrooted Cuttings

Your unrooted cuttings will arrive freshly cut. You will need to plant them immediately and begin a misting cycle to root the cuttings. This will leech the soil of nutrients, so during the propagation phase use a constant feed of 1/3 the normal recommended dosage of fertilizer until well rooted.

For best results with Petunias, we recommend using a constant feed program of 250-300 ppm N with an E.C. between 1.5 - 1.8. Remember to leach periodically in order to prevent salt build up. Maintain a pH between 5.8 - 6.2.

Flowering

Petunias require high light intensity (full sun) for peak finishing. If you grow them in the shade, you will get stretching and lower bloom performance. For the long nights of the winter months, supplemental light is recommended.

Pinching

Pinching is recommended 5-10 days after transplantation. A second pinch may be necessary depending on the size and shape of the final pot.

Spacing

Space pots adequately to allow for light penetration and airflow between foliage of adjacent pots. We recommend eight inches for 4” pots and twenty-four inches for 10” pots.

Height Control

Pinching and high light intensity are the best ways to control height. An initial pinch is recommended, but additional pinching may be necessary to shape your final product. Bonzi has been shown effective in 4” pot production.

Pests

Whiteflies, aphids, leafminers, and thrips are the biggest pest problems with Petunias.

Disease

Trlg Imagination Pevensie Purple are not prone to many diseases, but watch for botrytis while the days are short. This grey rot is usually associated with wet or humid conditions. You can prevent botrytis by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis are Medallion and Banrot. Use them as a drench according to each label’s instructions.

Planting Trlg Imagination Pevensie Purple Liners

1. We recommend planting 4-5 starter plants per 10 inch basket. Use a well-drained soil in your baskets and plant your starter plants deep, allowing the ellepot to be completely covered by the soil. If you are planting 4” pots, 1 plant per pot should be sufficient if you have enough time. Plant it directly in the middle of your pot.
2. Pinching is recommended 5-10 days after transplantation. A second pinch may be necessary depending on the size and shape of the final pot.

Unrooted Cuttings

Cuttings vary in size between different plant families, but most can be described as tip cuttings (ivy are leaf-and-eye stem cuttings not tips) that stick nicely in small plug trays such as the 105-plug tray we use (some varieties are better suited for a 50 cell tray, i.e. Angelwing Begonia, Bougainvillea, Setcrecea, etc.). Please do not order unrooted cuttings unless you are an experienced propagator with mist systems and proper temperature control.
