Second, the roots must be thinned in time, and the capillary roots of oleander grow very fast. Too many roots will form a ball, which will not only hinder the absorption of water and fertilizer, but also affect growth. If root thinning is not carried out in time, there will be withering, falling leaves and death. The best time for root thinning is from the beginning of August to the end of September. At this time, the root of oleander is dormant, which is a good opportunity for root thinning.

Proper watering is the key to good management of oleander. Improper watering in winter and summer will cause fallen leaves, flowers and even death, once a day in spring, and once every morning and evening in summer. And the leaf surface should be sprayed with water frequently to keep it moist. ✿ oleander picture appreciation 5

Culture method of oleander Picture of oleander

Flower bonsai network flower maintenance flower maintenance column: oleander culture method oleander picture oleander is oleander family oleander, alias willow peach. Bamboo pick for evergreen shrubs or Xiao Qiao wood, plant height 2 to 6 meters, single leaf whorl, leathery bright, leaf blade lanceolate, margin slightly anti-roll. Terminal Cymes, Corolla funnelform, red or white, single or double, flowers 4-5 cm in diameter, fragrant. The flowering period is from June to September and the fruit is ripe in December.

Oleander likes sunny, warm and humid environment, although it is not cold-resistant, but it is adaptable. It can be cultivated in open field in central and eastern China. Oleander is not strict with the soil, and can adapt to slightly acidic and slightly alkaline soil, but it is suitable for loose and fertile soil. Potted soil is best made of 30% rotten leaf soil or 30% compost soil, 30% dung dry soil and 40% sandy soil. Oleander grows fast and the pot should be changed when it is moved out in late April every year. In addition to changing the basin soil, a small amount of hoof horn should also be used as base fertilizer. From potted fresh bamboo peach to flower fade from September to October, the fermented sesame paste residue dry fertilizer should be applied once a month, and the application amount depends on the size of the basin, such as 50g for 20cm pot and 200g for 50cm pot. The pot is watered as soon as it is dry. If the basin soil is too dry and the leaves have wilted, you should first pour small water and wait for the leaves to slow down and then pour through the water.

Potted oleander should be reshaped and pruned once a year. When pruning, there are generally 3 main branches on each trunk and 3 branches on each main branch. Each branch should be cut at 20cm to 30cm from the base, which is the commonly used "three branches and nine tops" method of shaping and pruning, which will also cover the head of the flower branches.

Oleander can be propagated easily, cuttings can be cut in spring and summer, cuttings without leaves can also be used to propagate in the air with high temperature and humidity, it is easy to root, but after rooting, transplanting must be careful, otherwise it is easy to hurt the root. In addition, there is water insertion, that is, branches with leaves are inserted into the water, so it is easy to root and transplant. If there is no need for mass reproduction, the method of ramet reproduction can be adopted.
