Impatiens devendrae – Flowering plants
How to grow and care for
It thrives best in bright sunlight to partial shade for healthy growth. In an area with very hot summers, plant them in partial shade, or shade them from the afternoon sun. An excessive amount of sun may cause browning of foliage, though a lot of shade may make the balsam plant leggy and flowerless.
It grows well in an evenly moist, organically rich, well-drained, peat moss-based potting mix.
Water regularly, Keep the soil evenly moist but not soggy. Flowering plants are thirsty, and they dry out quickly in containers, so check them often. Impatiens will quickly wilt if they are allowed to dry out.
It prefers average room temperatures 60°F – 75°F / 16°C – 24°C. In winter do not let the temperature fall below 13°C (55°F).
Fertilize every two weeks from spring through fall with a high-potassium liquid fertilizer diluted by half.
It can be easily propagated by seed or stem cuttings. Sow impatiens seeds in spring or early summer. Germination takes 10 to 20 days at 75 degrees Fahrenheit. Take 10 cm stem tip cuttings in spring or summer. They’ll root easily in water or moist soil.
