Marigold Bloom Timing: Regional Norms and Phosphorus Boost

Ohio reference: Mid-May planting → July 4th blooms. Your Mississippi timing similar.

Actionable Boost

• Till in granular 10-30-10 (high phosphorus)
• Phosphorus = bloom nutrient
• Available at garden centers

Patience Principle

Proper beds + high-phosphorus boost + time = profuse bloom until frost. Plants follow their calendar, not yours.
