Days to Germination for Rose Parade Impatiens Seeds

Uses

• With their deep green foliage and baby rose-like blooms, Rose Parade impatiens can be used a number of ways. Since they thrive in shady spots, used as ground cover, they brighten up the understories of large trees. They make suitable container plants where, if hung from a rafter, spill their blooms over the side. Consider using the Rose Parade as edging plants or as a complement to other bedding plants, such as hostas.

Soil

• Rose Parade impatiens seeds require a loose, soilless mix in which to germinate. Seed starting mixes are available at nurseries and large home improvement stores. Make your own by combining one part peat moss with three parts perlite. When you transplant the impatiens into the garden, till the soil until it is light and fluffy to a depth of 10 inches and incorporate 2 inches of sand and 2 inches of compost into the soil. This mixture will provide the nutrients and quick drainage required to get the impatiens seedlings off to a good start.

Seed Germination

• Start the Rose Parade impatiens seeds indoors, eight to 10 weeks before the last frost date in your area. Scatter them across the surface of the soil and sprinkle a very thin layer -- no more than 1/8 inch -- of sand or perlite over the top. Impatiens seeds require light to germinate, so if you cover the seeds too deep, they may not sprout. Keep the soil moist and the germination container in an area that remains between 70 and 75 degrees Fahrenheit, and the Rose Parade seeds will germinate within 18 to 28 days.

Transplanting the Seedlings

• After the last frost begin hardening off the impatiens seedlings. Hardening off is a method whereby you gradually introduce the seedlings to the outdoors. For the first three days, place them in an area that is protected from wind and direct sun. Bring them back indoors after three hours. After the initial three days, begin lengthening the time the seedlings remain outdoors for 10 days. By then they should be able to withstand transplantation into the garden. Space the Rose Parade impatiens plants at least 12 inches apart and keep them moist at all times.
