Can you root impatiens cuttings in water? Yes. The RHS says impatiens root easily from softwood cuttings and that stems will also root if you strip the lower leaves and stand the bottom couple of centimeters (about 1 inch (2.5 cm)) in water. Take soft shoot tips in spring or early summer, keep them warm and bright, and pot them once roots form.
Key takeaway: Impatiens cuttings are a cheap way to multiply busy Lizzie (Impatiens walleriana) and New Guinea impatiens (I. hawkeri). The RHS says impatiens root easily from softwood cuttings taken from spring to early summer, and NC State Extension says New Guinea impatiens cuttings root in 8 to 18 days in a warm mist bed.

When Should You Take Impatiens Cuttings?
Spring to early summer. The RHS says impatiens root easily from softwood cuttings taken from April to June, using soft, flexible shoot tips from the current season’s growth. Cuttings taken in early spring should be ready to plant outside by early summer. Summer bedding impatiens are tender perennials that the RHS says are usually composted in early autumn, so taking cuttings first is a way to keep a favorite plant going.
- Best: soft, non-flowering shoot tips.
- Avoid: woody, damaged or diseased stems.
- Morning: cut when stems are fully hydrated.
How Do You Root Impatiens Cuttings in Water Step by Step?
Keep it simple. The RHS says impatiens stems root when you remove the lower leaves and immerse the bottom couple of centimeters in water. Use a clean glass in bright, indirect light, keep leaves out of the water, and refresh it every few days. Illinois Extension notes that tender plants with water-filled stems often root within a week.
- Cut a healthy, non-flowering shoot tip.
- Trim just below a leaf node.
- Remove the lower leaves and any flower buds.
- Stand the bottom 1 inch (2–3 cm) in clean water.
- Place in bright, indirect light away from direct sun.
- Change the water every few days.
- Pot up once roots appear.
How Many Impatiens Cuttings Should You Plant Per Pot?
More cuttings make fuller pots. NC State Extension recommends one rooted New Guinea impatiens cutting for a 4–5 inch (10–13 cm) pot, two for a 6 inch (15 cm) pot, three to four for an 8 inch (20 cm) pot and four to five for a 10–12 inch (25–30 cm) basket. It names a 3/4 to 1 inch (2–2.5 cm) tip as the best material for commercial propagation.
How Long Do Impatiens Cuttings Take to Root?
About one to three weeks. NC State Extension says New Guinea impatiens cuttings root in 8 to 18 days depending on variety, using 72–75°F (22–24°C) bottom heat in a mist bed, and a second NC State article says cuttings should root in two to three weeks. Water cuttings indoors may take a little longer if the room is cool.

Do Impatiens Cuttings Need Rooting Hormone?
No. NC State Extension says growth regulators are not required to root New Guinea impatiens cuttings. What matters more is preventing wilting: commercial growers use intermittent mist, and at home a clear cover over soil-rooted cuttings or a glass of water does the same job. Keep air at 65–75°F (18–24°C) and root zones near 70–75°F (21–24°C).
Should Impatiens Cuttings Go in Soil or Water?
Both work. The RHS describes both softwood cuttings in compost and rooting in water. Soil-rooted cuttings skip the transplant adjustment, while water lets you watch roots grow. Use a well-drained, low-nutrient mix; NC State Extension warns New Guinea impatiens are very susceptible to salt injury and says to use clear water, without fertilizer, for the first two weeks after potting.
Which Impatiens Can You Propagate Legally?
Check the label first. The RHS notes that some impatiens are protected by Plant Breeder’s Rights, so you may not propagate them for sale. NC State Extension says New Guinea impatiens cutting production is strictly controlled for most cultivars, with licensed propagators paying royalties. Rooting a few cuttings for your own garden is the common home use; never sell protected varieties.
How Do You Keep Impatiens Cuttings Healthy?
Start with clean stock. NC State Extension says to propagate from clean plants only and warns that western flower thrips spread impatiens necrotic spot virus (INSV) to impatiens and many other plants; our INSV guide explains the symptoms. The RHS says impatiens downy mildew affects busy Lizzie, causing yellowing and rapid leaf drop, while New Guinea hybrids are not affected.
How Do You Care for Rooted Impatiens Cuttings?
Pot them into moist, well-drained mix and keep them warm. NC State Extension says to avoid temperatures below 65°F (18°C) while growing New Guinea impatiens on, and that growth ceases at 60°F (16°C). The RHS says impatiens are killed by frost, so plant out only when night temperatures stay above 45°F (7°C), in part to full shade for busy Lizzie.
