New Guinea impatiens isconstantly being hybridized.
However, if you are happy with flower production and it has a full appearance, refrain from pruning.

However, a few cultivars have stabilized enough so that seeds are available.
To grow impatiens from seed, ensure you’re in it for the long haul.
Seeds must be started indoors about three months before the average last frost date.
Treat an infestation by first reducing the population with a spray from the garden hose.
Then, spray the plant with insecticidal soap.
Necrotic spot and tomato-spotted wilt can move into an inpatiens bed infested with thrips.
There is no cure for these viruses, so prevention is crucial.
Eliminating thrips will thwart the chances of disease moving in.
Downy mildew, botrytis blight, and verticillium wilt are fungal conditions that can affect impatiens with soggy soil.
you might prevent this by maintaining a consistent watering schedule and increasing the space between plants when planting.

Plant your starts about 18 inches apart in a mixture of soil and compost.
Maintain proper conditions, like light and soil, and then prune plants once they look leggy.
Clipping back spindly stems, in addition to perfect growing conditions, will encourage fuller growth.
