New Guinea Impatiens Harmony Salmon Cream Rooted Cutting Liner

For best results with New Guinea Impatiens, we recommend using a constant feed program of 100-150 ppm N. Maintain a pH between 5.8 - 6.2. New Guineas are very susceptible to salts injury so ensure proper run-off and plan for a clear water drench weekly.

Pinching is not recommended as New Guineas are free-branching plants. Pinching will delay flower production by 2-3 weeks, so it can be used as an effective timing tool to delay flowering.

Spacing too close will result in excessive stretching. Space pots adequately to allow for light penetration and airflow between foliage of adjacent pots. We recommend seven inches for 4” pots and eighteen inches for 10” pots.

Stretching is best controlled with high levels of light, proper watering, and low fertilization. If PGRs are desired for varieties that stretch, NC State has tested a foliar spray of Bonzi at 5-30 ppm with good results.

Spider mites and thrips are the primary pests attracted to New Guinea Impatiens.

Harmony Salmon Cream 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.

1. We recommend planting 4 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 not recommended.
