About Screw Pine
A striking tropical tree with a spiraling rosette of long, sword-shaped leaves arranged in a dramatic screw pattern around the trunk. Stilt-like aerial prop roots emerge from the trunk, giving it a prehistoric, architectural appearance. Not to be confused with the culinary pandan (Pandanus amaryllifolius), this species is grown purely for its bold ornamental form and is a landscape statement piece. Screw Pine belongs to the Pandanaceae family and originates from Madagascar; widely planted as an ornamental throughout the tropics including the Philippines..
Pandanus species are deeply woven into Philippine culture, though most Filipinos associate 'pandan' with the fragrant culinary variety. The ornamental Screw Pine is increasingly used in modern Filipino landscape design for its architectural quality, especially in coastal resorts and modern tropical gardens. The native Pandanus tectorius (locally called 'pandan dagat') has leaves traditionally woven into banig (sleeping mats) and bayong (market bags) in the Visayas and Mindanao. Screw Pine is available at larger nurseries and landscape supply centers.
Also known as: Pandan Tree.
Popular Varieties
- Pandanus utilis (standard Screw Pine with blue-green leaves)
- Pandanus veitchii (variegated white-edged leaves, popular ornamental)
- Pandanus amaryllifolius (fragrant pandan, culinary use, different species)
- Pandanus tectorius (Philippine native coastal pandan, woven into mats)
How to Plant Screw Pine in the Philippines
Screw Pine can be propagated through seeds, offshoots (suckers), stem cuttings. The recommended method is separation of basal offshoots from established plants.
Propagation Steps
- Step 1: Locate a well-rooted offshoot at the base of a mature plant.
- Step 2: Cut cleanly from the mother plant with a sharp knife, including some roots.
- Step 3: Let the cut dry for a day in shade.
- Step 4: Plant in sandy, well-draining soil mix.
- Step 5: Water sparingly until new growth appears (2-4 weeks).
- Step 6: Gradually move to a sunnier location.
Care Guide
Sunlight
Full sun to partial shade (full sun for best symmetrical growth). Position your screw pine where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Moderate watering; allow soil to dry slightly between waterings. Tolerates coastal salt spray and sandy soils. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity
Ideal temperature range: 25-35°C (tropical; does not tolerate frost). Moderate to high — adapts well to Philippine coastal and inland conditions The warm, humid Philippine climate is well-suited for growing screw pine outdoors or indoors.
Fertilizer
Balanced fertilizer (14-14-14) every 3 months during growing season. Responds well to organic compost.
Pruning
Remove old, yellowing lower leaves to maintain a clean trunk. Trim brown leaf tips with scissors. Allow prop roots to grow naturally.
Toxicity & Safety
Non-toxic. However, leaf margins have sharp spines that can scratch skin — handle with gloves.
Common Problems & Solutions
Brown, dry leaf tips
Cause: Low humidity or underwatering
Solution: Increase watering frequency. Trim brown tips for aesthetics. Mulch around the base to retain moisture.
Scale insects along leaf margins
Cause: Spiny leaf edges trap debris and harbor pests
Solution: Wipe leaves with neem oil solution. Remove heavily infested leaves.
Leaning trunk
Cause: Uneven light or wind exposure
Solution: Stake young plants. The aerial prop roots will eventually stabilize the tree naturally.
Mealybugs in leaf axils
Cause: Tight leaf arrangement traps moisture and pests
Solution: Spray forcefully with water to dislodge bugs. Follow with neem oil or insecticidal soap.
