Q. When can I transplant and propagate spirea?
Spiraea sp. is in the family Rosaceae family. It is commonly called bridal wreath or often just spirea. Taking cuttings of green wood in summer is often the most convenient way of increasing spireas. However, both leafy summer cuttings of firm shoots and leafless hardwood cuttings taken in fall are used for rooting.
Many spireas lend themselves to increase by removing root suckers or even by dividing the plants when they are transplanted. Divide suckering species, such as S. x billiardii and S. douglasii, in late autumn or early spring. Layering is also an easy way to multiply many kinds of spirea.
Grow your spirea in fertile, moist, well-drained soil in full sun.
