Answer:
You should use a sharp knife, a scissor or pruning shears to make the cutting. Make sure to cut the branch horizontally rather than vertically. The cut should be just below a leaf node or a set of leaves. The cutting should be between 3 and 5 inches and should contain at least two sets of leaves.
You can root your calamansi cutting in a peat pot. Peat pots decompose over time. When you go to plant the cutting in the soil you can plant the whole pot without disturbing the root system. Traditional plastic pots are also suitable.
