Calendulas

Calendulas, also commonly referred to as pot marigolds, are delightful annual flowers that can add a burst of color and beauty to any garden. These cheerful and versatile plants are known for their vibrant petals, ranging in shades from bright yellows and oranges to soft creams and apricots. With their distinctive daisy-like appearance and a range of sizes, calendulas make a charming addition to flower beds, borders, containers, and even herb gardens. Celenduals can be grown as annual or biennial (if temperatures never drop below zero).

How To Grow

Growing calendulas is relatively easy, making them an ideal choice for both beginner and experienced gardeners. Follow these simple steps to ensure successful growth and abundant blooms: Choosing the Right Location: Select a sunny spot in your garden for planting calendulas. These plants thrive in full sun, though they can tolerate some partial shade. Ensure the location has well-draining soil to prevent waterlogging, as soggy soil can lead to root rot. Soil Preparation: Prepare the soil by removing any weeds, rocks, or debris. Calendulas prefer fertile, loamy soil with a slightly acidic to neutral pH level. If your soil is heavy or clay-like, consider adding organic matter such as compost to improve its texture and drainage. Sowing Seeds or Transplants: Calendulas can be grown from seeds or transplants. If starting from seeds, sow them directly into the garden after the last frost date. Scatter the seeds lightly over the prepared soil and cover them with a thin layer of soil. Water gently to keep the soil moist but not waterlogged. If using transplants, which are young calendula plants purchased from nurseries or started indoors, transplant them into the garden once the danger of frost has passed. Dig a hole slightly larger than the root ball, place the transplant in the hole, and gently firm the soil around it. Water thoroughly to help the plant establish itself. Watering and Care: Keep the soil evenly moist but avoid overwatering, as calendulas are susceptible to root rot. Water at the base of the plant, taking care to avoid wetting the foliage. Mulching around the plants can help conserve moisture and suppress weed growth. Feeding: Calendulas are not heavy feeders, but they can benefit from a balanced, water-soluble fertilizer applied once a month during the growing season. Follow the manufacturer's instructions for proper dosage and application. Pest and Disease Control: Calendulas are generally resistant to pests and diseases. However, keeping the garden area clean and removing any dead or decaying plant material can help prevent issues such as aphids or fungal diseases. If necessary, treat pest or disease problems with organic insecticides or fungicides.

How/When To Harvesting

Harvesting calendula flowers is a rewarding experience. Follow these steps to ensure a bountiful harvest: Choosing the Right Time: Harvest calendula flowers when they are fully open and in their prime. Look for vibrant, undamaged blooms with their petals fully extended. Morning is often the best time to harvest, as the flowers tend to be fresher and have not been affected by the heat of the day. Harvesting Method: To harvest calendula flowers, hold the stem just below the flower head and gently twist it to detach the bloom from the plant. Alternatively, you can use sharp garden scissors or pruners to cut the stem about an inch below the flower head. Post-Harvest Care: After harvesting, place the calendula flowers in a clean container with water immediately to maintain their freshness. Remove any leaves or foliage that may be submerged in the water to prevent bacterial growth. Store the flowers in a cool location away from direct sunlight until you are ready to use or dry them.
