What are the latest propagation methods for oleander?
Oleander, also known as gou na and yang tao mei, has large, showy flowers that are highly ornamental, and it likes to grow in warm, humid environments, so many people cultivate it in their courtyards. In spring, when all things revive, it is a good time to propagate oleander, so how should oleander be propagated? Follow the editor and take a look.
1. Seed propagation
Seed propagation is the most common propagation method for plants. After the fruit of oleander matures, it can be harvested and sown. If seedlings are cultivated in a greenhouse, they generally only need three months to emerge. If cultivated outdoors, sowing needs to be done in autumn, and they will gradually grow only around Qingming in the following spring.
2. Layering propagation
The layering propagation method for oleander is generally carried out during the rainy season. This is the period of vigorous growth for oleander, with a high survival rate, and branches close to the ground can be selected. When layering, first cut a wound on the branch, then bury the wound in the soil and secure it. Because it is the rainy season, there is no need to water much, and the branch can generally take root in about 60 days. After rooting, it can be separated from the mother plant and replanted in another plot with suitable conditions. Seedlings propagated by this method have the excellent characteristics of the mother plant.
3. Cutting propagation
The branches selected for cutting propagation must be free from pests and diseases, and only branches that are robust and of excellent quality can be used as cuttings. After the branches are cut off, they should be directly shortened, and then cuttings can be made. To increase the survival rate during cutting, the cuttings need to be bundled together and soaked in rooting powder for 2-8 hours, which can significantly improve the cutting survival rate. When cutting, use loose soil, as this is beneficial for rooting and survival.
4. Water cutting propagation
In addition to normal soil cuttings, oleander has extremely strong vitality, and water cutting propagation can be carried out as long as it is in the growing season. Cut the removed branches into about 30-40 cm, then split the base by about 4-6 cm, and then place them in a container. Note that the water in the container should not be too deep. Also pay attention to the water temperature. They generally take root in about 15-20 days. In summer, when temperatures are high, change the water frequently to avoid root rot caused by water quality deterioration. After rooting, a small amount of fertilizer solution can be added to the water to promote strong seedling growth.
