If you google “propagating Rosemary from cuttings” you will find many resources that say it’s easy.
The most common method you will find is sticking it in water.
So i cut new sprigs with green stems cut at an angle from my healthy plant. I removed the leaves from the bottom 2.5 inches. Then, i stuck in in water. I changed water every 2 days.
The leaves and stems are browning and it has only been 4 days. Rooting takes anywhere from 2 to 4 weeks. It looks like these cuttings aren’t going to form roots. I will let it sit around some more, in the hope that something might grow. Maybe the weather down here is too hot and humid for the water method.
