Should you cut back New Guinea impatiens?

Taking a proactive approach and routinely trimming will encourage flowering and healthier branching and lead to a more dense plant.

How do you keep New Guinea impatiens blooming?

Impatiens plants bloom best with some shade, a requirement that often leads to misunderstanding.

Avoid planting your impatiens in full sun.

What do you do with impatiens at the end of the season?

How do you prepare impatiens for winter?

Water indoor impatiens sufficiently to keep the potting mix just moist during the winter months, when the plant's growth slows down. Fertilizer should not be required. To discourage impatiens from growing leggy, pinch off the tips of the stems above the nearest side shoot about once per month.
