I took four cuttings of Jersey in July and rooted two of them. One died after being transplanted. The remaining one was kept in an unheated garage over winter and then spent the summer potted outside. It’s now about 5 inches tall. Considering how inexpensive blueberry plants are in the spring at places like Home Depot and Walmart it’s not worth the effort rooting cuttings unless it’s a special variety or many plants are needed.
