Impatiens Impatiens Sun Harmony Deep Orange = 'Dhar328' (PBR) (Sun Harmony Series) (NG)

Water

New Guinea Impatiens should be watered regularly to maintain evenly moist soil, especially in the heat of summer. Water deeply to saturate the root zone at least once a week, although you may need to water more frequently during prolonged dry spells or when temperatures are particularly high. Avoid shallow watering, which can lead to weaker root growth. On average, this might translate to about 1 gallon of water per plant each week, but this can vary based on climate and soil conditions. Ensure proper drainage to prevent waterlogging, which can cause rot.

Light

New Guinea Impatiens thrive in bright, indirect light or dappled sunlight. They are tolerant of some direct sunlight but perform best when shielded from the intense midday sun, which can scorch their leaves. A spot that receives morning sun followed by afternoon shade or filtered light throughout the day is ideal.

Temperature

New Guinea Impatiens prefer temperatures between 70 and 85 degrees Fahrenheit but can tolerate a range from about 60 to 90 degrees Fahrenheit. They may not survive temperatures that drop significantly below 60 degrees Fahrenheit for prolonged periods. The ideal temperature range for robust growth and flowering is on the warmer side of their tolerance.

Pruning

Pruning New Guinea Impatiens is beneficial to encourage bushier growth and more blooms. Pinch back the stem tips every few weeks to promote branching, focusing on leggy or overgrown stems. The best time for pruning is in late spring or early summer as the plant starts to take off in growth, and thereafter, as needed to maintain shape and vigor.

Cleaning

As needed

Soil

New Guinea Impatiens thrive in well-draining, rich organic soil with a pH of 6.0 to 6.5. For best growth, mix peat moss, potting soil, and perlite in equal parts to ensure moisture retention and good drainage.

Repotting

New Guinea Impatiens should typically be repotted every 1-2 years during spring. Choose a container slightly larger than the previous one to give roots room to grow.

Humidity & Misting

New Guinea Impatiens prefer high humidity levels, around 50-70%. They flourish when the air is moist but not too wet, which helps their foliage stay healthy.

Suitable locations

• Indoor

  Place in bright, indirect light and keep soil moist.

• Outdoor

  Choose partial sun location, protect from strong wind.

• Hardiness zone

  10-12 USDA

Life cycle

New Guinea Impatiens 'Sun Harmony Deep Orange' begins its life cycle as a seed that germinates in warm, moist soil, typically in late winter or early spring in greenhouse conditions. After germination, the seedling develops true leaves and grows rapidly, transitioning into the vegetative stage where it focuses on leaf and stem growth. As the plant matures, it enters the flowering stage, usually in late spring or early summer, producing vibrant deep orange blooms that attract pollinators and can self-fertilize to produce seeds. Throughout the summer and into fall, the plant continues to flower profusely as long as it is provided with enough light and kept from extreme heat. As temperatures cool and daylight shortens, the plant transitions into senescence, where growth slows, and flowers drop off, signaling the end of its annual lifecycle, as New Guinea Impatiens are generally treated as annuals outside of their native tropical climate. However, some gardeners may overwinter the plants indoors or propagate cuttings to preserve the plant for the following season.

Propogation

• Propogation time

  Spring-Early Summer

• The Impatiens Sun Harmony Deep Orange is typically propagated using seed or cuttings, with cuttings being the more popular method due to the plant's patent protection, which can restrict the use of seeds for propagation without permission. To propagate from cuttings, a healthy, non-flowering stem approximately 4 to 6 inches (about 10 to 15 cm) long is taken with a sharp, clean tool. This cutting should have at least two sets of leaves. The bottom set of leaves is removed, and the cut end is dipped in rooting hormone before being placed in a well-draining potting mix. The container is then kept moist but not waterlogged, in bright, indirect sunlight at a warm temperature until roots develop, which can take several weeks. Once the cutting has established a strong root system, it can be transplanted to its final location.
