I have never been good at keeping a rosemary plant alive during winter indoors. It will not last outdoors in our climate, so they are dug up and brought inside.
I took a cutting from my outdoor plant, and put it in water, changing the water daily. I forgot to write the initial start date, but....
Here it is in August, and it has new life showing. So happy! By the way, the top turned brown at the beginning of potting this, so I cut back on the water. I also used soil specified for cactus type plants. If I can keep it alive all winter, I can start my own plants in the spring again, and not have to buy them.Here is a photo of the current growth. I'm so happy.
I enjoyed doing this, considering you could do this to sell plants, or share with family/friends too. Maybe a barter? With this day and age, we need to all help each other. Everyone I know is broke right now, or struggling with the high prices.
I attempted to propagate a few more cuttings too, but I think the earlier in the season works much better. It's in it's growing stage then, so your success rate is better.
