Propagating New Guinea Impatiens
New Guinea impatiens are the perfect flowers to choose for shaded areas of your landscaping. They will add an explosion of color in these areas from early summer to fall. One of the many wonderful things about new guinea impatiens is that they are very easy to care for and do not require a lot of maintenance. They will thrive as a potted plant and directly sown into the soil. However, they will not tolerate frost very well as they are very sensitive to any type of cold weather. Propagating new guinea impatiens is a good way to keep new flowers growing throughout the winter for spring sowing. There are a few different ways to propagate your new guinea impatiens.
Taking a cutting of the impatiens in the fall will keep the flower growing throughout the winter inside your home. They will do quite well in the home where it is warm as long as they can receive some sunlight during the day.
Cut the stem of the new guinea impatiens about 4 to 6 inches below the bloom. You can use regular scissors for this as the stem is not stiff or hard. It is quite soft and can even be broken by hand. The need for a clean cut is not necessary with your impatiens. Remove all the leaves on the bottom of the cutting and any buds or blooms. By doing so, you are helping the plant conserve its energy and put it towards making roots.
Place cutting in a jar of water and do not let any leaves touch the water. Place it on a windowsill that will receive some sunlight during the day. Keep watch on the jar each day until you see roots forming. It will take a few days for this to happen. Once the roots have formed, place the new guinea impatiens in a pot full of potting soil. Place it on the windowsill and water regularly.
If you do not take any cuttings of the flower in the fall, you can propagate through seed in the winter. Start the seed about 6 weeks before the frost leaves the ground.
Place the seed in a small plastic container with about ¼ inch of water. Place a thin plastic cover over the container and place in a warm area that has some sun. Watch until the seed begins to sprout.
As the seed sprouts, move the seedling to a small pot with soil in it. Form a small hole with your finger in the middle of the pot and place the seedling in it. Cover over lightly and mist with water. Place the pot where it will receive filtered sunlight. After a few weeks, you should see a small impatiens forming. When the frost leaves the ground, you can sow the flower into the soil in your garden. If you want to keep the flower inside, just transplant to a new pot or window planter. Your impatiens will grow quite nicely and supply you with great looking blooms throughout the season.
