ข้อเท็จจริงสำคัญ

• Triggered by high temperatures (above 24°C / 75°F for lettuce), long days, or water stress
• Plant shifts energy from leaf production to flowering and seed set
• Leaves become bitter, tough, and unsuitable for fresh eating
• Bolted plants develop a central flower stalk (called a scape in some crops)
• Prevention: maintain cool temperatures, use short-day or heat-tolerant varieties
• Indoor growing advantage: controlled photoperiod and temperature prevents bolting year-round
