I do. One of my favorite flowers is geraniums. I bought them for my hanging baskets during my first year of gardening. After paying full retail prices, I decided to find a less expensive, but same quality, option.
I taught myself how to use geranium cuttings from existing plants to grow new plants. I am now on my fifth generation of plants.
Here's how to do it !
Here is a dug up and repotted, 1 full season old, geranium brought indoors for the winter. I haven't trimmed off the dead leaves yet. My priority was to get it indoors before the first hard frost. I have about 20, full-sized plants spending the winter near upstairs windows.
Take the plant, rotate it around, and look or a good "branch" or stem. I look for the one's that are sticking out to the side. I get to make a new plant and shape the larger plant at the same time.
Follow this method and you can save a lot of money making your own geraniums from cuttings!
