You can move this tough shrub any time it is leaf less or dormant so November through April is best. However if you see new growth and still are itching for a move, play the odds and move the plant if you promise to keep it watered while it makes new roots. You may not have as many blooms the year after a transplant but it will adapt and adjust and you get to have this flowering shrub right where you want it. Keep growing, Marianne Binetti
