I have cut the old growth of my Autumn Joy because I like the appearance of the new healthy greens that are sprouting. Now I have collected a number of stems with the dry tops of last years bloom. Can those be replanted? Do I root from the dry tops or doI put the stem and all in water to root? As you can see I am new at this.

The stems you have cut are most likely dead plant material that won't root. You can cut spent blossom stalks in fall if you wish. In spring you run the risk of cutting the crown or new sprouts. Sedums need good drainage and will rot when kept too wet, so they can't be rooted in water. They are best propagated from seed, or cuttings placed flats of moistened, well-drained medium, such as perlite or vermiculite. The stems with roots at their joints easily make new plants when moved. Cuttings are best done in spring and summer when the greatest growth occurs. Feel free to visit anytime - we're here to help you enjoy and succeed in gardening!
