Propagation of Rhododendron alabamense Rehd.
Rhododendron alabamense Rehd., commonly known as the Alabama Azalea, is a native shrub that can be propagated using various methods, including seeds, cuttings, and layering.
Propagation by Seeds
Seeds are a viable method for propagating Rhododendron alabamense Rehd. Collect seeds during the summer or fall, and plant them in late winter or early spring. Before planting, soak the seeds in warm water for at least 24 hours to soften the seed coat.
You can also germinate rhododendron seeds in a plastic ziplock bag. Place the seeds in a moistened paper towel, seal the bag, and store it in a warm and bright spot. After they germinate, move the seedlings to pots with well-draining soil.
Propagation by Cuttings
Cuttings are another effective method for propagating Rhododendron alabamense Rehd. Take cuttings from the current year's growth during the late spring or early summer. Choose healthy, vigorous stems and cut just below a leaf node. Remove all leaves on the bottom half of the cutting leaving only two or three leaves at the top.
Dip the cuttings in rooting hormone and plant in a pot with a loose soil mix. Water the cuttings regularly and cover with a plastic bag to maintain high humidity and encourage rooting.
Propagation by Layering
Layering is a useful method for propagating Rhododendron alabamense Rehd. in the fall after new growth has hardened. Choose a low stem and make a wound or scratch on the underside of the branch. Apply rooting hormone to the wound and cover it with soil. The section should remain attached to the parent plant and is not cut until roots develop. After several months, roots will begin to develop, and the cutting can be detached from the parent plant and transplanted.
