Conocarpus erectus (Button Mangrove) is a native tree to Tropical America and it is suitable for bonsai types. It has a spreading crown and grows between 10-20 ft in height, with a diameter of 20 cm. Its evergreen leaves are oblong to lance-shaped, 2-4 inches in length and arranged alternately. The tree is also known for its ethnomedical uses where the leaves are eaten or their decoction is drunk for reducing fever. Furthermore, it is an easy plant to take care for and is relatively tolerant to seaside and salt.
This plant is hardy to USDA Zone 9-11 and prefers full sun to semi-shade. It requires moderate water and well-drained soil to keep its roots moist. If you live in cold regions, make sure to protect your plant during winter and grow it in a pot with well-draining soil. If the soil remains dry, you might consider adding some compost or other materials to improve drainage. You should also water your plant once in a while, making sure not to overwater or to make the soil stay soggy.
In addition, depending on your soil pH level, you may need to feed your plant with an appropriate fertilizer. The best feeding strategy for this plant is to apply a slow-release fertilizer which contains essential nutrients and minerals such as nitrogen, phosphorus and potassium. If your soil has too much salt, use a dilute solution of fertilizer instead.
So, if you are looking for an easy to take care plant, that can be used for bonsai, can tolerate salt and enhance your garden with its evergreen leaves, Conocarpus erectus (Button Mangrove) is the perfect choice.
