Key Takeaways:

  • Calendula Flowers Care: Calendulas are easy to grow, requiring minimal maintenance besides regular watering, deadheading, and ensuring the soil has a pH between 6.0 and 7.0. They flourish in nutrient-rich soil and prefer full sunlight, though they can tolerate partial shade.
  • Maximizing Blooms: To maximize the number of blooms, proper spacing of the seeds is essential. Provide them with ample sunlight, ensure the soil stays moist, regularly deadhead spent flowers, and reduce watering as the root system develops. 
  • Companion Plants: Marigold flowers serve as excellent companion plants for calendulas. They not only add beauty but also deter pests and nematodes, protecting your garden’s health and vitality. 
  • Medicinal Benefits: Calendula is known for its multiple medicinal properties. Its oil is often used to soothe irritated skin, reduce inflammation, and promote wound healing. Additionally, it has antimicrobial properties, making it beneficial for treating minor cuts, burns, and skin conditions like eczema and psoriasis. 
  • Edible Uses: Calendula’s petals and leaves can be used in many culinary creations such as salads, infused oils, baked goods, and herbal teas due to their mild, slightly peppery taste.

Calendula Flower Care Tips

To ensure healthy growth and continuous blooms, make sure you plant and space your calendula plants correctly in the garden. Calendula seeds germinate quickly, so you can directly sow them in the garden bed.

Plant the seeds about ½ inch deep and 10 inches apart. Within 5 to 10 days, you’ll see seedlings emerging.

If you prefer, you can also start the seeds indoors 4-6 weeks before the last frost.

Calendula thrives in nutrient-rich garden soil, so choose a well-draining soil with a pH between 6.0 and 7.0. It requires minimal maintenance to bloom and thrive.

Maximizing Blooms

For maximum blooms in your calendula garden, make sure to space your plants correctly and provide them with adequate sunlight. Here’s what you need to know:

  • Proper Spacing: Plant calendula seeds ½ inch deep and 10 inches apart. For established plants, space them 8 to 12 inches apart, with rows spaced 18 inches apart. This allows for airflow and prevents diseases like powdery mildew while ensuring the spread of blooms.
  • Sunlight Requirements: Calendulas thrive in full sun conditions, so plant them in an area that receives at least 6-8 hours of sunlight daily. While they can tolerate partial shade, full sun produces the most vigorous blooms. Adequate sunlight is crucial for their growth and development.
  • Watering: Keep the soil moist when planting seeds and caring for young plants. As the root systems develop, reduce watering frequency. Mature calendula plants are drought-resistant and require less direct care.
  • Deadheading: Regularly deadhead spent flowers to promote continuous blooms. This practice encourages profuse flower production and ensures a beautiful, blooming calendula garden.

Companion Plants for Calendula

Marigolds, which are from the same family, also help repel pests and nematodes in the garden. These vibrant flowers not only add beauty to your garden, but they also serve as excellent companion plants for calendula.

By interplanting marigolds with your calendula plants, you can naturally deter common garden pests like slugs. The strong scent of marigolds acts as a natural repellent, keeping these unwanted visitors away from your precious flowers.

Additionally, marigolds can help control nematodes, microscopic pests that can damage plant roots.

By planting marigolds alongside your calendula, you create a pest-repelling barrier that helps protect the health and vitality of your garden.
