You also need to make sure that the scissors are sharp. Blunt instruments will damage the parent plant. You are looking to make a cut as clean as possible.
While looking for a cutting for propagation it is important to get at least two nodes. Nodes are the bumps on the stems and branches where the leaves emerge from.
The reason you require two nodes is cos you will need to have one node under the surface of the soil or water while planting it. The other will remain above the ground it is from here that new leaves and shoots will emerge from.
Step-2: Leaves removal
Once you have a good enough cutting you are a step closer to propagate citronella. You will need to make sure that all the leaves are taken off. Too much greenery on the cutting will drain the moisture which is required for the rooting process. If the cutting dries out before the roots form you will not be able to use the cutting.
You can leave just a leaf or two on the cutting provided they are small. If there are bigger leaves trim them to three fourth the size and leave them be.
Tip: you are looking for leaves of the size of a bottle cap
Step-3: application of rooting agent
When you are dealing with cuttings the use of a good rooting agent becomes imperative. Rooting compounds are not very expensive and you can get a jar and use it as and when required. There are also homemade rooting agents that can be used to promote the rooting process.
