Growing Impatiens Flowers: Planting the Seed, Transplanting and/or Root Division

The following resources offer effective, healthy and/or well-rounded options. Click the links to go there now...

Sow your impatiens seeds in early spring. Fill a seed tray with your own sieved compost or a nutrient-rich seed starting mix. Water lightly before sowing the seeds. Sprinkle seeds lightly on the compost then cover with another fine layer.

Place in a cold frame or on a windowsill. Once true leaves emerge, prick out into modules to allow each plant to grow its own root system. Harden plants off as the temperature warms up towards the end of spring.

Impatiens can also be grown from softwood cuttings. Take these in spring or summer to overwinter. Cut off shoots about 4 inches (10 cm) long. Remove all the leaves apart from those at the tip. Push the shoot into compost so that just the leaves are left resting on the top. Keep them moist while the roots develop.
