Growing Lubeg: A Guide to Cultivating and Utilizing the Philippine Cherry

Lubeg (Syzygium lineatum), locally known as Malubeg or Alebadu, is a lesser-known fruit tree that naturally grows in northern regions of the Philippines, particularly thriving in regions like Cagayan Valley and Apayao. A member of the Myrtaceae family, this indigenous tree produces small, deep purple fruits that are rich in antioxidants and vitamin C. Today, this fruit is gaining attention for its potential in both agricultural and food-processing ventures.

Here’s a detailed care guide for cultivating Lubeg effectively:

Propagation Methods for Lubeg

1. By Seeds

• Most traditional method.
• It may take 3 to 5 years before the tree bears fruit.
• Best started from ripe fruits.

2. By Grafting

• Grafting from a healthy mature tree (scion) onto a strong rootstock is possible.
• Faster fruiting (1–2 years).
• Advantage: Ensures consistent fruit quality and vigor.

3. By Marcotting (Air Layering)

• Suitable for Lubeg, especially if you’re replicating a productive tree.
• Roots typically develop within 3–6 weeks.
• Offers a faster and more predictable method of propagation.

Growing Conditions and Fertilizer Needs

Soil and Location

• Soil Type: Well-draining loamy soil rich in organic matter.
• pH Range: 5.5–6.5
• Location: Full sun, elevated areas that do not flood.

Fertilizer Recommendations

For Young Trees (0–1 year):

• Organic compost or vermicast: 3–5 kg per planting hole.
• Complete Fertilizer (14-14-14): 100–150g every 3 months.

For Fruit-Bearing Trees (2+ years):

• Urea (46-0-0): 100g per tree every 4 months to boost growth.
• Organic fertilizer: Apply yearly, especially before the rainy season.
• Potassium fertilizer (e.g., 0-0-60): Enhances fruit size and sweetness.

Tip: Use mulch such as dried grass or rice straw to conserve soil moisture and suppress weeds.

Common Pests and Diseases

Pests:

1. Aphids and Mealybugs – Suck sap from leaves and young shoots.
   • Solution: Spray with neem oil or mild dish soap solution (1 tbsp per liter of water).
2. Fruit Borers – Bore holes into fruits, causing spoilage.
   • Solution: Harvest fruits promptly and use light traps at night.

Diseases:

1. Anthracnose (fungal disease) – Causes black spots and rotting of fruits or leaves.
   • Solution: Use copper-based fungicide every 10–14 days, especially in wet seasons.
2. Leaf Spot – Brown or black patches on leaves.
   • Solution: Remove affected leaves and apply a suitable fungicide.

Care and Maintenance Tips

• Regular pruning – Prevent overcrowding of branches, improve airflow and sunlight penetration.
• Weeding – Keep the base of the tree free from weeds.
• Watering – Especially important in the first year; water 2–3 times a week during dry spells.
