New Guinea impatiens need a daily water check on dry days in the summer, especially if they're growing in pots.
Impatiens flaccida grows best at temperatures between about 50 and 85 degrees F (10-29°C), with nights that are cool.
Fertilizing -- Feed weekly with a very dilute (1/8 strength) liquid fertilizer. Hydroponic fertilizer is ideal for this, because it is easily absorbed and contains all essential nutrients. After 6-8 weeks, you may switch to a granular fertilizer that contains micronutrients, following the dosage on the package. Or continue feeding weekly with liquid fertilizer at 1/8 strength.
Impatiens flaccida grows vigorously to about 18 inches tall and wide. Its leaves are large, lush, and thick, making this a first-rate hanging plant. .
Impatiens are one of those plants that benefit from "pinching," or pruning off spent blooms as well as stems. Pinching back stems encourages branching growth that makes the plants more bushy, while also promoting the development of new buds and flowers.
Impatiens flaccida grows best at temperatures between about 50 and 85 degrees F (10-29°C), with nights that are cool. It doesn't seem to like cold temperatures, and it probably cannot survive frost.
