Use soil

Guangdong evergreen likes loose, fertile, humus rich and slightly acidic soil with good drainage. Potting soil can be prepared with peat soil or fine sand soil and a small amount of stable manure

Temperature

Guangdong evergreen likes a warm living environment and is not resistant to cold. The overwintering temperature should be kept above 5 ℃ to 8 ℃ in order to grow normally. The suitable temperature for overwintering of Guangdong evergreen of three varieties of Leucaena javanica, Leucaena macula and Leucaena leaf should not be lower than 18 ℃

Illumination

Guangdong evergreen likes half shade environment and is extremely resistant to shade. It is afraid of direct sunlight. It can be cultivated and maintained indoors for many years. Even in places with too dark light, it will not grow in vain like other plants. Avoid direct sunlight in summer. When the light is strong, it is easy to cause dry tips, scorched edges and even withered and yellow of leaves, affecting the viewing effect. Therefore, shade after leaving the room in early spring

Watering

In addition to keeping the basin soil moist in summer, Guangdong evergreen should not be watered too often in spring and autumn, and should be controlled in winter. Evergreen is a fleshy root, so it is most afraid of ponding. If it is watered too much, it is easy to rot. However, the air must be kept moist. If the air is dry, adverse phenomena such as dry tips of leaves are easy to occur. In the early dry season, pay attention to spraying water around the plant to increase the air humidity

Fertilization

In spring and autumn, applying rotten cake fertilizer and water every 3 ~ 4 weeks can make the plant grow strong and the leaves green. During the growth period, liquid fertilizer dominated by nitrogen fertilizer is applied every two weeks

Diseases and insect pests

Evergreen is vulnerable to leaf spot, anthrax, scale insects and brown soft ants during its growth, so we should pay attention to prevention and control

Pruning

If the evergreen plant is too tall and the plant shape is not good, it can be kept for short cutting after 1 ~ 2 knots, and the re germinated plant will grow more vigorously. The cut branches with top can be directly inserted into the water bottle for viewing, and white tender roots can grow after about 30 days. In addition, before and after the beginning of summer, several old leaves on the periphery of the adult plant should be cut off to facilitate the germination of new buds, new leaves and pumping flowers and plants
