Calendula

Grow calendula in well-drained soil with a pH of 6.0-7.0 and moderate fertility. A small amount of compost is usually sufficient; deadheading extends flowering, especially in cool weather.

Tips

• Sow seeds about 1/4-1/2 inch deep and thin seedlings to 10 inches apart.
• Supply about 1 inch of water weekly while allowing the soil surface to dry between waterings.
• Mix a modest amount of compost into the bed and avoid excess nitrogen fertilizer.
• Watch for powdery mildew and improve air circulation rather than wetting foliage.
• Remove faded blooms regularly, or pick fresh, pesticide-free flowers if you want their edible petals.
