🌱 Tips for Success

• Start seeds indoors 6–8 weeks before transplanting.
• Provide consistent moisture — dry soil can cause “buttoning” (tiny heads).
• Maintain even temperatures; avoid heat stress for compact heads.
• When heads begin to form, wrap outer leaves over them to protect from light (keeps them white and tender).
• Fertilize every 2–3 weeks with a balanced organic fertilizer.

💧 Watering Tip

Cauliflower prefers steady moisture. Water deeply and regularly to prevent the heads from becoming loose or bitter.

🌼 Fun Fact

Cauliflower is actually a flower! The edible head is an undeveloped cluster of flower buds.
