Tips on Growing Impatiens From Seed

Growing impatiens from seeds is a slow process, but a simple one. Fill each cell with a moistened commercial seed-starting mix, leaving a ½ inch (1.5 cm.) space between the top of the soil and the edge of the planter. Put the cells on a tray and fill the tray with water. Allow the mix to soak up water from the bottom until the top of the mix is moist. Pour the rest of the water out of the tray. Place two seeds on top of the soil in each cell and sprinkle a light dusting of mix over them. Mist the top of the cells with clear water. Cover the cells with plastic to keep in moisture, and place it in a bright spot to sprout.

Once the seeds have sprouted and have produced a pair of leaves, remove the plastic and place the tray filled with cells in a sunny south window. If you don’t have a bright window available, grow the impatiens under fluorescent lights for 16 hours a day. Some garden experts argue that, while propagating impatiens by seed does need an initial burst of sunlight to wake up the seeds, they grow stockier and stronger if you then move them to a dark area. Experiment with this theory by leaving the seeds uncovered and in a bright, sunny window for the first two days. Then, sprinkle the seeds with starting mix, cover with plastic and move them to a dark place to sprout.
