About MacArthur Palm
An elegant, slender clumping palm that produces multiple thin trunks with smooth green crownshafts and feathery, arching fronds. Its clustering habit creates a lush, tropical grove effect that is perfect for screening and garden backdrops. Named after Sir William MacArthur, it is one of the most widely planted palms in Philippine landscapes due to its fast growth, easy care, and graceful form. MacArthur Palm belongs to the Arecaceae family and originates from Papua New Guinea and northern Australia. Extensively cultivated throughout the Philippines as a landscape palm..
MacArthur Palm is one of the most commonly planted palms in Philippine subdivisions, resorts, and commercial landscapes. Its affordable price, fast growth, and clumping habit make it a go-to choice for privacy screening and garden backdrops. You will see it in nearly every major subdivision from Ayala Alabang to Nuvali to Cebu's South Road Properties. Seedlings are widely available and very cheap (50-150 pesos for seedlings). The name has a pleasant connection to General Douglas MacArthur's Philippine legacy, though the palm is actually named after a different MacArthur.
Also known as: Cluster Palm, Hurricane Palm.

Care Guide
Sunlight
Partial shade to full sun (prefers filtered light or morning sun with afternoon shade). Position your macarthur palm where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Regular watering; keep soil consistently moist. Not as drought-tolerant as some palms — wilts in prolonged dry spells. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity

Fertilizer
Palm fertilizer with magnesium (8-2-12 + Mg) every 3 months. Responds well to regular feeding with faster growth.
Pruning
Remove only fully dead, brown fronds. Do not cut green or yellow fronds. Remove old fruit clusters and dead trunks from clumps.
Toxicity & Safety
Non-toxic. Fruits are not edible but not harmful.
Common Problems & Solutions
Yellowing fronds
Cause: Magnesium or potassium deficiency
Solution: Apply palm fertilizer with extra magnesium. Epsom salt foliar spray (1 tbsp per gallon) helps.
Frond tip burn
Cause: Too much direct afternoon sun or drought stress
Solution: Provide afternoon shade. Increase watering frequency. Mulch around the base.
Scale insects on crownshaft
Cause: Pests favoring smooth crownshaft surface
Solution: Wipe crownshaft with neem oil solution. For heavy infestations, use systemic insecticide.
Excessive self-seeding
Cause: Birds eat the bright red fruits and scatter seeds throughout the garden
Solution: Remove fruit clusters before seeds fully ripen. Pull volunteer seedlings as they appear.
