Impatienses are easy to grow from seed but as the name implies, it will take some time. As a matter of fact, it will take 3 months for the seeds to grow before they are ready to plant. While this is a long period, it is still worth the time and effort to grow your own impatiens from seed.
To begin this process, starts off with a calendar. To know when to plant your seed, you will need to count back 3 months from you local frost-free date. Once you have this date, you can begin the planting process.
This process begins with the container or flat. Regardless of which you choose you will need to process the container before planting. How do you do this? Well, the process is easy and starts off with clean water with a little squirt of dish soap. Once you have your basin filled with this, the next step is to scrub the container of your choice to remove soil, and debris. Next, rinse it in clear water with a little bleach added. After that is done, remove from the water and allow to dry.
After you container is dried, the next step is to fill with soil but do not fill it all the way. You will want about ½ an inch left from the top of the soil to the top of the container. Next, moisten the soil to the point that you see moisture come out of the bottom. Once that happens, dump out the water and begin the planting process.
To plant impatiens seeds, will require one to sprinkle them on top of the soil surface. Impatiens seeds are pretty small so the easiest approach is to sprinkle. Next, dust a thin layer of soil on top and mist with water. Then, place a thin layer of clear plastic or glass on top of the container and place in a sunny location. As soon as you begin to see little green dots of growth, remove the top and place back in the sunny location. Continue to grow until your seedlings have two sets of true leaves.
The next step of this process is transplanting, which should only occur once the seedlings have two sets of true leaves. After the seedlings have developed two sets of true leaves, transplant them into a four pack or a 3 inch pot.
Once they have been transplanted, continue to monitor soil moisture until you are ready to plant them outside.
