Once a popular plant in many gardens and courtyards, oleander is loved for its showy flowers and unique form. However, in recent years, oleander has gradually been pulled into the "blacklist" by flower friends, and the reasons can be described as multifaceted. Here, I will introduce in detail the four main reasons why oleander is considered "unsuitable for maintenance", and I hope that the majority of flower lovers can choose plants rationally to avoid potential problems.
Although the flowers of oleander are gorgeous, their flowering ability is relatively poor, which is a common problem reported by many flower lovers. Compared to other flowers, oleander has a relatively short flowering cycle and a limited flowering time. Many people expect oleanders to bloom all year round, but this is often not the case.
When caring for oleanders, flower lovers may find that the flowering period of the plant is more concentrated, and it is difficult to see the flowers at other times. This short flowering period is not only disappointing, but also makes oleanders less attractive in the garden.
The root system of oleander is prone to decay, which is a serious problem faced by many flower lovers in the maintenance process. Oleander roots are extremely sensitive to moist environments, and if the soil is poorly drained or overwatered, it can easily lead to root rot. Decaying roots can directly affect the plant's ability to absorb nutrients, resulting in stunted plant growth and even overall plant weakness.
In order to avoid the problem of oleander root rot, flower lovers should choose well-drained soil when planting and ensure that the soil can quickly drain excess water after each watering. In addition, proper pruning can also help to improve the ventilation of the plants and reduce the chance of moisture in the roots.
Oleander leaves are prone to yellowing, which can be caused by a variety of reasons, including insufficient soil nutrients, pest and disease infestation, too much or too little water, etc. The yellowing of the leaves not only affects the beauty of oleander, but also directly affects its normal photosynthesis and nutrient absorption.
When caring for oleanders, flower friends should pay close attention to the color changes of the leaves and take corresponding measures in time. Reasonable fertilization, moderate watering, and timely control of pests and diseases are all effective means to maintain the health of oleander leaves. In addition, it is important to regularly check the pH of the soil to ensure that the soil is suitable.
Oleander is relatively weak in cold tolerance and is easily damaged in cold climates. In the cold winter, oleander often has yellowing leaves and dead branches, affecting the overall growth of the plant.
In order to improve the cold tolerance of oleander, flower lovers can take some measures before the onset of winter, such as covering and insulation, moving indoors, etc. In addition, in cold climates, moderately reducing the amount of watering to avoid overly moist roots can help reduce the problems caused by root rot.
On the whole, although oleander has a unique attraction in the appearance of flowers, due to its poor flowering ability, easy root rot, easy yellowing of leaves, and poor cold tolerance, more and more flower friends have listed it as one of the plants that are "not suitable for maintenance". When choosing plants, we should look at the characteristics of each plant rationally in order to better meet our own conservation needs. Hopefully, these questions and hints about oleander will help you make informed plant choices for a more beautiful and healthy garden.
