Caring for an Oleander tree is simple and only requires that you keep a few things in mind. Oleander plants are fragrant evergreen trees that are one of the most popular shrubs in the US. Because of the little work needed to maintain them and their ability to thrive in poor soil conditions with little water, oleanders are grown throughout the northern and southern sections of the country. Their bright flowers that bloom in the summer and the wonderful fragrance they bring are of the chief reasons for the plants’ popularity. They are often used for privacy because they retain their leaves all year round.
Since they don’t need incredibly rich soil Oleanders can be planted anywhere they will receive ample direct sunlight throughout the year. Water is usually a big issue with plants, but in the case of Oleander plants you don’t have much to worry about. In the case of severe or prolonged drought conditions water the plant once per week to prevent damage.
Oleander trees in general do not require fertilizer, but fertilizer can be used in cases where extra growth is desired or the plant is not responding well to the soil. Store brought tree fertilizer applied at the beginning of fall and once again and the beginning of spring is all that is necessary.
Pruning is not required of Oleander trees for their health, but you can still prune for aesthetic reasons. Pruning should be done in early fall and no later than October. Prune low hanging branches at the branch nodes, where they enter the tree.
Once the Oleander plant is established even less care is needed. Mature plants are usually able to survive and thrive without watering, fertilizer, or outside help of any kind. The only for you to do is to pay attention to water conditions and make sure no pests affect the tree.
As an important side note: Oleanders are highly toxic and can make humans or animals very sick if they ingest leaves, twigs, or flowers. Exercise caution if you have small children or pets.
