New Guinea impatiens are a popular choice for gardeners who want to add a splash of color to their shady spots. These plants are easy to grow and care for, and they produce large, showy flowers in a range of colors from spring to fall.
New Guinea impatiens need regular watering to keep the soil evenly moist but not soggy. They do not tolerate drought and will wilt if the soil dries out. In hot summer months, this may mean daily watering that soaks deep into the root zone. In winter you can reduce the frequency to once or twice a week.
Place the plants in an area that receives bright but indirect sun for optimal growth and flowering. Indoors, place them near an east or west-facing window.
The plants prefer loamy soil that's rich in organic matter and drains well. If the growing medium is too heavy or clayey, you can amend it with compost or peat moss to improve its texture and drainage. When growing in containers, use a good-quality potting mix designed for flowering plants.
They can benefit from regular feeding during the growing season. Use a balanced fertilizer formulated for flowering plants. Alternatively, apply a slow-release dressing once at the beginning of the growing season.
Occasionally deadhead and pinch.
You can propagate by seed, cutting, or division.
