1、 Curing conditions

1. Watering: it is very important to grasp the amount of watering when maintaining oleander. If it is not watered correctly, the plant may die. Watering can be carried out every day in spring and twice a day in summer when the temperature is slightly higher. At ordinary times, water should be sprayed properly to clean the dust of the leaves. Watering should be controlled in winter

2. Fertilization: about 20% of the base fertilizer should be applied when the pot is put into the pot. The fertilizer should be applied once before the Qingming Festival, and the bean cake water should be applied once every 10 days after the Qingming Festival; Fertilizer should be applied once after the autumn equinox, and once every 10 days after the autumn equinox

3. Pruning: prune the plants in spring, and cut off all the long and thin branches. Over dense branches also need appropriate thinning, so that the plant will grow fuller

2、 Breeding method

1. Sowing method: generally, when the fruit is ripe, it is collected and sown while sowing. After sowing, the pot soil is put into the greenhouse, and the seedlings will grow in 3 months

2. Water insertion method: during its growth, cut a section of branches about 30cm with a knife, cut the bottom about 4-6cm with a knife, and insert it into the container containing water. New roots will grow in about half a month. Note that you need to change the water before rooting

3、 Disease control

Brown spot and black spot are the main hazards of plants, so management needs to be strengthened at ordinary times. When planting, don't be too dense. Apply fertilizer appropriately to make the plant grow stronger. After the occurrence of disease, the diseased leaves need to be cleaned up, and carbendazim or chlorothalonil should be sprayed for control in serious cases
