2. Starting From a Clipping
If you want to root a plant or cutting in water, add aspirin or two to the container. purchase a cheap bottle of aspirin and grind it up before you join it to the water. This helps in water absorption and will aid the cutting to start roots.
You can simply commence plants from cuttings from roses, geraniums, and saliva. Just dip the cuttings into a rooting hormone, then put them into potting soil. Spray the cuttings multiple times daily with water until you make sure they are rooted. Hibiscus is also easy to root this way.
