Everything You Need to Know About Thai Basil — Care, Propagation & More
Your complete Filipino gardener’s guide to growing, caring for, and harvesting Balanoy Thai — from seed to stir-fry.
What Can You Eat?
Discover the edible parts and how Filipinos enjoy this plant in everyday cooking.
Thai basil is the essential herb in pad krapow (Thai basil stir-fry) and green/red Thai curries, both hugely popular in Filipino-Thai fusion restaurants. Fresh leaves are also added to Vietnamese-style pho, spring rolls, and spicy stir-fried dishes. Its anise-like flavor holds up well under high heat cooking.
With the explosion of Thai food popularity in Metro Manila, Thai basil has become a sought-after herb in urban gardens. It is hardier than sweet basil in tropical heat and humidity, making it better suited to year-round Philippine growing. Many Filipino home cooks now distinguish between sweet basil, Thai basil, and native albahaka.

Spot issues early and fix them fast.
Japanese beetles or leaf chewers

Solution: Hand-pick pests in the morning. Spray with neem oil. Use row covers for severe infestations.
Fusarium wilt
Cause: Soil-borne fungal disease causing brown, wilting stems
Solution: Use sterile potting mix. Remove affected plants immediately. Rotate planting locations.
Root rot in monsoon season
Cause: Waterlogged soil during heavy rains
Solution: Ensure excellent drainage. Elevate containers. Move under cover during prolonged downpours.
Sparse, leggy growth
Cause: Insufficient light or failure to pinch tips
Solution: Move to sunnier spot. Regularly pinch growing tips to encourage side branching and bushier form.
