How to propagate oleander? A few practical propagation methods to teach you
Oleander blooms from May to October, with a flowering period lasting as long as half a year, hence it also has the elegant name "Half-Year Red." The main means of propagating oleander are cuttings and sowing. 1) Cutting propagation. During shaping and pruning, the small side branches sprouting from the main trunk of the oleander should be regularly cut off, so that they do not interfere with the tree shape and consume nutrients. Using these small side branches as propagation material, they are most likely to survive after cuttings. These small branches are all relatively short; although thin and weak, their tissue is relatively plump, and they also carry terminal buds, so they take shape quickly after rooting. When cutting the above-mentioned cuttings

How do you make oleander form a "three-fork, nine-top" crown?
Oleander has whorled leaves in threes and is a typical three-fork brancher, meaning that after each pruning, 3 new shoots grow from the stem nodes. People can take advantage of this branching trait to prune and shape it so that it becomes a "three-fork, nine-top" plant. When the main trunk grows to a certain height, pinch off the top, and 3 main branches will grow from the main trunk. When the main branches grow to about 20 cm or more, keep 20 cm on each and pinch off the tops again to make them sprout new shoots. On each main branch, keep another 3 branches, keep 20 cm to 30 cm on each branch, and cut off all the upper branches.

How to prevent and control pests and diseases of oleander? A detailed guide to practical methods
1. After aphids are found, spray the plants with a 40% dichlorvos emulsion at 800 times dilution, or with water in which cigarette butts have been soaked; when there are only a few, they can also be brushed off. For other control methods, refer to the pest and disease control section for Chinese rose and scarlet sage. 2. Scale insects damage the branches and leaves. Control method: spray the plants with Jiesha at 2000 times dilution. For other control methods, refer to pest and disease control for crape myrtle. 3. Black spot disease This disease occurs easily under high temperature and high humidity and damages the leaves. After it appears, spray with 50% carbendazim at 500 times dilution or thiophanate-methyl at 600 times dilution. For other control methods
