Detailed Guide to Oleander Propagation Methods: Teach You to Grow Robust Seedlings

Nursery Stock 0 views
Oleander, also known as willow-leaf peach, is an evergreen shrub of the genus Nerium. It likes light and prefers a warm, humid climate. It is not demanding about water and highly adaptable to soil, and can resist smoke, dust and some toxic gases. Oleander leaves resemble bamboo leaves and its flowers resemble peach blossoms; it blooms in summer when few other plants are in flower, and its flowering period is long. Above all, it is a vigorous tree, making it an important landscaping species for streets, green belts, industrial and mining areas and other places with poor soil conditions. Propagation methods include cuttings and layering, with cuttings being the main method. (1) Cutting propagation: Hardwood cuttings are taken in spring or early spring. Select thick branches about 1-1.5 cm in diameter (sucker shoots can be used), cut them into 15-20 cm long cuttings, tie dozens of cuttings together in sequence, and soak the lower about 1/3 in water for about 10 days. Change the water frequently so that the soaking water does not spoil. When the soaked part of the cutting turns white and the top becomes sticky, take it out and insert it into the seedbed. Cuttings that have undergone water treatment grow very fast and have a high survival rate; generally they can root 15-20 days after insertion. Oleander can also be propagated by water rooting. Place the lower part of the cuttings in 20°C water for 30-40 days, changing the water frequently, and they will also root easily. Then plant the rooted cuttings in a seedbed for cultivation, but it is best to provide shade. (2) Layering propagation: Oleander is also very easy to propagate by layering. Layering is generally done in the rainy season. Before layering, wound the branch near the ground, press it into water, and after about 60 days it can be separated from the mother plant to obtain a new plant.
