Whereas stem cuttings are the preferred technique of propagation, vegetation will be propagated by different means.
- Root: Some woodies, similar to sassafras (Sassafras albidum, Zones 4–9) and sumac (Rhus spp. and cvs., Zones 3–8), and a few perennials, similar to backyard phlox (Phlox paniculata and cvs., Zones 4–9), Stokes’ aster (Stokesia laevis, Zones 5–9), blackberries (Rubus spp. and cvs., Zones 6–9), and big coneflower (Rudbeckia maxima, Zones 4–9), propagate properly from root cuttings. For root cuttings, reduce roots into 3- to 6-inch sections. Lay the roots right into a tray and canopy them thinly with roughly 1 inch of potting substrate. Hold the tray moist, and in a couple of month you need to begin seeing shoots emerge.
- Culm: Culms are the shoot growths that emerge off grass rhizomes similar to big reed (Arundo donax*, Zones 6–10) and sugarcane (Saccharum officinarum, Zones 9–10). These culms will be reduce after which laid horizontally in rising substrate in order that they’re half-buried. New shoots and roots will emerge from the node (the round traces across the stem).
- Leaves: Leaf propagation is a enjoyable means for gardeners to make extra houseplants. It’s notably enjoyable for kids, who can shortly see the leaves take root. African violet (Saintpaulia ionantha, Zones 11–12), begonia (Begonia spp. and cvs., Zones 6–11), and echeveria (Echeveria spp. and cvs., Zones 9–11) are all nice candidates. The top of the leaf nearer to the foundation is just caught into the substrate. African violet and begonia leaves will also be suspended in water to assist make new roots. The veins on the beneathaspect of begonia leaves will be sliced with a knife to encourage wound tissue to kind.
