Propagating lilac bushes from cuttings is tricky, but definitely not impossible. Take cuttings of lilac bushes from tender new growth in late spring or early summer, and take several cuttings to increase your chances of success. Some plants develop roots quickly in a glass of water on a sunny windowsill, but this practice isn’t usually recommended for lilacs. If the stem develops roots, plant the cutting in a pot and let it mature until the young plant is well established, then move it outdoors.
