About
Thai basil is the liquorice-mint square-stemmed workhorse of stir-fries and phở—purple stems, pointed leaves, and flower spikes bees treat like a runway. Distinct from sweet basil; do not substitute unless you enjoy flavor chaos. Grow spring through fall; bolts in heat but keeps producing if you steal tips. Frost ends the party—extend with row cover or pots. ☀️💧 Sun and Water Requirements: Full sun, rich well-drained soil, steady moisture. Wilts fast in pots—mulch and check daily in August. ✂️ Propagation: Seed indoors after last frost or direct sow warm soil; cuttings root in water in a week if you forget to label them. 🌾 Harvest / Best Use Timing: Pinch tips and flower spikes for continuous kitchen harvest until frost stops growth.
Permaculture Functions
- Edible: Liquorice-anise basil for stir-fries, phở, and hot-climate kitchens.
- Pollinator: Flower spikes pull bees when you allow bloom between harvests.
- Pest Management: Strong scent may confuse some pests—companion use, not a magic shield.
Practitioner Notes
- Blanch or process within hours if you are freezing—enzymes keep chewing while paperwork waits.
- Cluster patches three feet or wider—tiny one-offs get ignored by bees cruising for volume.
- Soil smell and root color tell more than gadget overload—dig a small hole twice a season.
- Overfertilized fast growth dilutes flavor and invites sap feeders—lean soil often tastes more like itself.
