Oleander not only has bright flowers but also high ornamental value. However, when cultivating oleander, how to create a suitable growing environment is a question worth paying attention to. And whether oleander prefers shade or sun has always been a controversial topic. Therefore, this article will analyze from multiple perspectives to explore the growing environment needs of oleander.
Ecological Overview of Oleander
Before understanding the growing environment needs of oleander, let's briefly introduce its ecological environment. Oleander is native to the Indochinese Peninsula and northeastern India, and is a plant with strong drought, cold, and salt tolerance, and high stress resistance.
Oleander's Light Requirements
Although oleander is shade-tolerant, its demand for sunlight is also high. In southern China, the duration and intensity of direct sunlight are greater, so oleander prefers a semi-shaded and semi-sunny environment; in the north, a sunny location should be chosen.
The Harm of Excessive Sunlight for Oleander
If oleander is exposed to strong sunlight for a long time, it will cause its leaves to fade, wilt, or even get sunburned. When planting, choose a location with good shade or take sun protection measures.
Oleander Likes a Warm Environment
Oleander is a tropical and subtropical plant with high temperature requirements. The suitable temperature range for growth is 20°C-30°C. When the temperature is too low or too high, it will adversely affect the growth of oleander.
Oleander has Strong Drought Tolerance
Oleander has good drought tolerance, so it does not need to be watered too much when cultivated. However, during the summer drought period, appropriate watering can increase its growth rate.
Oleander's Soil Requirements
The soil requirements for oleander's growing environment are not high, as long as it is well-drained, fertile, and loose. If the soil is too heavy, it is recommended to add an appropriate amount of well-rotted organic fertilizer.
Oleander Loves Fertilizer
Oleander is a plant that loves fertilizer, so attention needs to be paid to the selection and application of fertilizers. Summer is the peak growing season for oleander, and it is recommended to apply more potassium fertilizer and organic fertilizer to increase its drought resistance and nutrient absorption capacity.
Does Oleander Need Pruning
During the growth process, oleander needs appropriate pruning. Cutting off dead branches and leaves, keeping the main trunk clear, is beneficial for its branching and lush growth.
Precautions During Oleander's Flowering Period
Oleander has a long flowering period, but some issues need to be paid attention to during this time. During the high temperatures of summer, flowers are prone to withering. During the flowering period, the frequency of watering should be appropriately increased to keep the soil moist.
Prevention and Control of Oleander Leaf Diseases
The leaves of oleander are relatively tender and susceptible to diseases and pests. During the growth process, prevention and control need to be strengthened, and water on the leaves, weeds, and dead leaves should be cleared in time to avoid the spread of diseases.
Protection of Oleander's Root System
The root system of oleander is relatively fragile during its growth process and needs protection. When transplanting, be careful not to damage the roots. At the same time, when planting, also pay attention to leaving enough space for its growth.
Oleander Prefers a Well-Drained Environment
Oleander prefers a well-drained environment, so drainage measures need to be taken when planting. If the soil drainage is poor, it is easy to cause root rot in oleander, thus affecting its normal growth.
Oleander Dislikes Wind
Oleander dislikes windy environments because wind can easily cause its flowers to wither and leaves to fall off. When choosing a planting location, pay attention to selecting a wind-sheltered environment.
The Legend of Oleander's Flower Language
Oleander is a plant rich in cultural connotations. In Chinese, oleander has the meaning of "refusing guests". In legends, oleander is also associated with meanings like "longing" and "parting".
Conclusion
Through the introduction of oleander's growing environment needs, it can be seen that oleander likes both sun and shade, but its requirements for the environment are not high. As long as suitable conditions such as light, temperature, water, and fertilizer are provided, oleander can grow strong and show off its beautiful flowers.
