My grandmother used to root Impatiens a lot. You don't need anything fancy. I've chosen shotglasses.
Gather some cuttings and place them in clean water. Try to angle the cut slightly and scrape the side of stem a bit.
I'll keep them on my bathroom windowsill until roots magically appear.
A little over one week and roots are starting to appear.
Get a good root system established before planting them in soil.
I'm going to plant in this old log. I'm at the cottage, so a rustic look will do fine here. Keep Impatiens out of direct sunlight.
I used regular potting mix and a coffee filter to line the log. Its hard to see, but these cuttings have lots of buds and will flower soon.
I remember the huge plant that my grandmother kept inside all winter. All you need is one plant to start and you can have several in no time!
