Marigold

Marigolds thrive in well-drained soil with a pH of 6.0-7.0 and average fertility. Add compost to poor soil, avoid heavy nitrogen feeding, and remove spent blooms to maintain flowering.

Tips

• Sow seeds about 1/4 inch deep and space compact plants about 10 inches apart, allowing more room for tall types.
• Water deeply when the surface soil dries, aiming for about 1 inch weekly during dry weather.
• Fertilize lightly only if growth is weak, since excess nitrogen favors leaves over flowers.
• Check leaf undersides for spider mites during hot, dry weather and rinse them off with water.
• Pinch off faded flower heads just above the next leaf or branch.
