Right now is a perfect time. I use coarse sand (river sand) to strike cuttings. I also use hormone powder as I think it improves the strike rate considerably. ( It is readily available in garden departments and a lot of nurseries as " Rooting Powder" '" Cutting Gel" etc.)
I have tried tip cuttings and stem cuttings and both seem to work with duranta ( Sheena's Gold and Geisha Girl). Dip the stem in the hormone powder and use a stick ( a pencil is good) to make a hole in the sand for the cutting. Firm the sand around the cutting. I generally do a lot in each pot and move them into larger pots when they have reasonable root growth. Water in well, but from then on keep the sand just moist - never wet. How do you tell when they have good root growth? Pull one out and check it. That's the beauty of having plenty in each pot.
It is also possible to start duranta cuttings in a container of water. I prefer the sand method as I feel I get stronger root growth.
