Why Coriander Bolts Faster Than Any Other Kitchen Herb
Coriander has the shortest productive window of any herb commonly grown on Indian balconies — even a well-tended plant typically bolts to flower and seed within four to six weeks in warm weather, which is why serious growers treat it as a crop to re-sow every month rather than a perennial herb like mint or curry leaf. This fast bolting is a heat response built into the plant, not a sign of poor care, and it's the reason coriander grown in peak Indian summer rarely lasts long enough to be worth harvesting at all. A separate, purely mechanical issue trips up many first-time growers at the sowing stage: whole coriander seeds are actually two seeds fused together, and germination rates improve noticeably when the seed is gently crushed or split in half before sowing, rather than sown whole straight from a spice jar.

🌱 Quick Care Guide
- 🌱 Soil: Rich mix. 40% compost + 60% potting soil. Slightly acidic pH 6.0–6.8.
- 💧 Water: Keep lightly moist. Never waterlogged. Morning watering only.
- ☀️ Sun: 4–6 hours. Partial shade tolerated but reduces flavour intensity.
- 🌿 Fertilizer: Monthly diluted liquid feed (half-strength). Avoid heavy nitrogen.
- ✂️ Harvest: Harvest outer leaves — never more than ⅓ at once. Pinch flower buds.
⚠️ Common Problems & Fixes
| Problem | Cause | Fix |
|---|---|---|
| Bitter taste | Plant going to seed (bolting) | Pinch off flower buds immediately |
| Yellow leaves | Overwatering or nitrogen deficiency | Improve drainage · Add diluted liquid fertilizer |
| Leggy stems | Too little light or not harvesting | Move to window · Harvest regularly |
| Root rot | Waterlogged soil | Repot in well-draining mix · Reduce watering |
