💧 Irrigation Management
Gemma Plus requires consistent soil moisture for optimal head development.

| Vegetative | 2–3 times per week | Maintain even moisture |
| Head Formation | 3 times per week | Critical stage for head firmness |
| Pre-Harvest | Reduce watering | Helps prevent splitting and rot |
For farmers with drip irrigation, maintain a uniform flow to keep soil moisture balanced throughout the root zone.
