How to Grow Impatiens
Busy Lizzies are commonly brought as young plants from garden centers. While Impatiens can be grown from seed, this can be a difficult process.
Starting Busy Lizzies From Seed
Sow Impatiens seeds undercover 8 to 10 weeks before your last local frost date.
Busy Lizzies require warm soil, at least 75°F, and light to germinate. If soil temperature is not maintained during germination the Impatiens seeds will rot.
Sow the Impatiens seeds in trays or pots filled with fresh or sterilized soil. Water with hot water, at least 100°F. Repeat this process after an hour.
When the soil has cooled sow the impatiens seeds thinly. Simply press the Impatiens seed into the soil. Don’t cover the Impatiens seeds.
Sow Busy Lizzie seeds on top of the soil. Loosely cover to prevent the Impatiens seeds from baking in the humidity. The cover can be removed once the seeds have germinated.
Cover the trays or pots in a loose plastic bag. This is intended to maintain humidity. Keep the bag loose to prevent the humidity from rising too much and cooking the seeds. Place the trays in a light position and keep the soil warm, 75-80°F.
On a bright day you can lightly mist the Impatiens seeds. This helps to maintain humidity levels but is not necessary for successful germination. Don’t overdo misting. Also don’t mist on cool or cloudy days.
If germination is successful, white Impatiens sprouts will emerge from the seeds within 7 days. This process may take slightly longer in cooler climates. Some Impatiens varieties may also take longer to germinate.
Following germination, allow the seedlings to grow on until they are large enough to transplant.
How to Plant Impatiens

In shaded landscapes and in Zones 9 and higher the Impatiens plants will reseed. This allows you to enjoy Busy Lizzies throughout the year.
Impatiens desire to sit in moist positions means that the soil should be rich and well draining. If the soil isn’t well draining the roots will begin to rot.

Busy Lizzies do best in partial or full shade. If you want to plant the Impatiens flowers in full sun the Impatiens will need to be acclimatized to the position. This is done by slowly exposing the Impatiens flowers to increasing amounts of light over the space of a week.

You can dip the cutting in rooting hormone to encourage propagation but this is not necessary.
Place the cuttings in trays or pots filled with fresh potting soil. You can also place cuttings in a damp mixture of perlite or vermiculite. Water well and place in a bright but indirect light.
