Japanese Rose (Hibiscus) cutting propagation is not a hard operation if you respect some basic rules regarding cutting manufacture, choosing the substrate and providing an optimal temperature. The right time for multiplying is spring or autumn, but it can also be sown in other seasons.
When you prepare to cut the sprouts to make the cuttings, look carefully at the plant. Choose the top-of-the-line cuttings. It will be great if you spray the sprouts with a stimulant (eg Clonex spray) 2 days before the cutting. Of course, you can propagate it without this procedure.
– For cutting propagation at the Japanese Rose (Hibiscus), you should prepare 3-4 knots cuttings.
– Cut a few millimeters under the last node.
– Remove the leaves to the last pair of knots.
– This way you’ll reduce transpiration, and the plant will focus its effort to produce new roots, not to feed the rest of the organs.
– You can also pass the base of the stem through a rooting stimulant that will help the plant form new roots faster.
It would be great to put the cuttings into a mixture made of equal parts of fibrous and perlite peat. For more safety and to create a microclimate, you can cover the planted sprout with a plastic bottle or a glass bell. The cuttings give roots quite easily and in water containers. You can change the water periodically, otherwise you risk that the new roots will rot.
If you want to multiply Japanese Rose (Hibiscus) by cuttings, you should provide an optimal temperature of 71.6-77 degrees Fahrenheit and high air humidity (85-90%). Under these conditions, the seedling will give roots in about a month. When they are developed enough, the new plantlets move into pots. You must pinch them once or twice for branching.
