Cocos nucifera 'Malayan Dwarf': 'Malayan Dwarf' Coconut Palm1

Edward F. Gilman and Dennis G. Watson2

Introduction

One of man's most useful plants. The heavy crown of long flowing fronds and gently curved trunks of Coconut Palm lend a tropical effect to any landscape setting in which they can grow. A beautiful street tree, Coconut Palm is also ideal as a background tree, framing tree, or as a striking freestanding specimen. Coconut Palms located along streets, walkways or near patios require pruning to remove the flowers or developing fruit so it doesn't fall and cause injury or property damage.

Fruit

Use and Management

Due to the widespread devastation of lethal yellowing disease, use the resistant Malayan strains, often called dwarf or pygmy coconuts, and labelled yellow, golden, red, and green, according to the color of their fruits, such as `Golden Malayan Dwarf'. The Malayan palms are very similar to the Jamaican Tall except for having straight trunks. The red strain is the most rugged of the three (more resistant to lethal yellowing) but has the least attractive foliage. Fronds have a distinct yellow cast to them and many people prefer the green frond types. Unfortunately, the green frond types are less resistant to lethal yellowing disease. The variety `Maypan', a hybrid of Malayan x Panama Tall, has the most robust and rapid growth yet retains its resistance to lethal yellowing disease. It also grows well on poor sites. All Coconut Palms are highly salt-tolerant and make nice street trees if planted when they are tall enough. Be aware that falling fruit can damage vehicles or hit pedestrians and the flower stalks (in spring) or developing fruit (summer) may need to be removed.

Coconut Palms grow in full sun on any well-drained soils. Plants respond well to being fertilized. Malayan Dwarf selections require more fertilizer and may be more susceptible to palm aphids than Jamaican Tall coconut palms.

Propagation is by seed. The large coconuts, with outer husk, should be half-buried on their side in soil. Germination can take many months.

Pests

Nematodes may infest this palm.

Diseases

Lethal yellowing disease, virus diseases, and fungi all affect Coconut Palms. Be sure to only plant selections which are resistant to lethal yellowing disease. Ganoderma butt rot can infect the lower trunk and roots, and can kill the palm. Avoid injury to the palm in this area. There is no control for butt rot, only prevention.
