New Guinea Impatiens Harmony Colorfall Neon Red Rooted Cutting Liner

For best results with Harmony Colorfall Neon Red, plant one rooted liner per 4- or 6-inch container or 10-inch basket. Use a well-drained soil with a pH of 5.8-6.2, EC of 0.8-1.0, light feed (100-125 ppm N), and average daily temperatures of 65-70 degrees. This plant doesn't require pinching and can be sensitive to salt. Chemical growth regulators aren't usually necessary, but New Guinea Impatiens will respond to Uniconazole at transplant and paclobutrazol shortly before finishing. Watch for aphids, thrips, botrytis, and root rot.

Bright red flowers bloom from spring to frost.

This plant doesn't require pinching.

Space containers for adequate airflow and sunlight penetration the base of each plant. We recommend spacing 4-inch containers 7" apart and 10-inch containers 18" apart. 

This plant doesn't typically need PGRs. However, it will respond to a drench of Uniconazole at 5-7 ppm at transplant and a Paclobutrazol drench of .25-.50 ppm two to three weeks before reaching its finished size. High light intensity, low fertilizer, and proper watering are the best ways to control stretching for Harmony Colorfall Neon Red.

You may see aphids and thrips.

This plant isn't prone to disease, but botrytis and root rot can develop in overly wet or humid conditions. Prevent infection in your greenhouse with a few basic steps:

1. Water at the base of each plant in the morning and allow the soil to dry out between watering.

2. Space containers so air and sunlight can reach the soil level of each plant.

3. Provide good airflow in your greenhouse. We recommend using horizontal airflow fans.

We recommend planting one rooted plug per 4-, 6-, or 10-inch container. Use a well-drained soil and completely bury the ellepot in the middle of the container.
