Comprehensive guide for starting and caring for calendula seeds:

Starting Calendula Seeds

Indoors:

Timing: Start seeds indoors 6-8 weeks before the last expected frost date. Zone 4b, March 30th

Containers: Use seed trays or small pots filled with seed-starting mix.

Planting Depth: Sow seeds about 1/4 inch deep.

Light: Place the trays in a sunny location or under grow lights. Calendula seeds need light to germinate.

Watering: Keep the soil consistently moist but not waterlogged.

Germination: Seeds typically germinate in 7-14 days.

Outdoors:

Timing: Direct sow seeds outdoors after the last frost date when the soil has warmed up.

Location: Choose a sunny spot with well-draining soil.

Planting Depth: Sow seeds about 1/4 inch deep.

Spacing: Space seeds about 6-12 inches apart.

Watering: Keep the soil consistently moist until seedlings emerge.

Planting Out

Hardening Off: Gradually acclimate indoor seedlings to outdoor conditions by placing them outside for a few hours each day, increasing the time over a week.

Transplanting: Transplant seedlings into the garden after the last frost date, spacing them 6-12 inches apart.

Soil: Ensure the soil is well-draining and enriched with compost.

Calendula, while versatile, has some plants it doesn’t pair well with in the garden. Avoid planting calendula near:

1. Marigolds: Both are in the daisy family and can compete for nutrients and water, potentially weakening each other.
2. Nasturtiums: They attract similar pests, like aphids and whiteflies, making pest control more challenging.
3. Tomatoes: They share susceptibility to diseases like blight, increasing the risk of spreading infections.
4. Beans: Calendula roots can stunt bean growth and disrupt beneficial nematodes.
5. Cabbage: While calendula can repel pests from cabbage, it often attracts them itself, harming its blooms.

Plant Care

Watering: Water regularly, keeping the soil consistently moist but not waterlogged.

Fertilizing: Calendula is not a heavy feeder, but you can add a balanced organic fertilizer or compost to the soil.

Deadheading: Remove spent flowers to encourage continuous blooming. Remember to save your seeds.

Saving calendula seeds is a rewarding and straightforward process that allows you to enjoy these beautiful flowers year after year. Here’s how you can do it:

1. Wait for Seed Maturity: Allow the calendula flowers to bloom and fade naturally. The seed heads will form where the flowers once were. Wait until the seed heads turn brown and dry on the plant.
2. Harvest the Seeds: Once the seed heads are dry, gently remove them from the plant. You can do this by cutting the stem just below the seed head or by carefully pulling the seed head off.
3. Separate the Seeds: Break open the seed heads to release the seeds. Calendula seeds are curved and resemble small, dry crescents. Remove any remaining plant debris.
4. Dry the Seeds: Spread the seeds out on a paper towel or a screen in a well-ventilated area. Allow them to dry completely for a few days to ensure they are free of moisture.
5. Store the Seeds: Place the dried seeds in a labeled envelope or a small glass jar with a tight-fitting lid. Store them in a cool, dark, and dry place until you’re ready to plant them next season.

By saving calendula seeds, you not only ensure a continuous supply of these vibrant flowers but also contribute to sustainable gardening practices.

Pests and Diseases: Calendula is generally pest-resistant, but watch for aphids and powdery mildew. Use organic pest control methods if needed.

Cut Flower Care

Cutting Time: Harvest flowers early in the morning when they are fully open.

Trimming Stems: Trim stems at a 45-degree angle to maximize water absorption.

Water: Place stems in clean, tepid water immediately after cutting.

Vase Care: Use a clean vase and change the water daily to prevent bacteria buildup.

Flower Food: Add flower food to the water to nourish the flowers and extend their vase life.

Calendula, also known as pot marigold, is a versatile and beneficial herb commonly used in soap and salve making. Here’s how you can use calendula for these purposes:

Calendula Soap

Calendula soap is gentle and soothing, making it ideal for sensitive or irritated skin. The petals of the calendula flower are infused into oils, which are then used to create the soap. The anti-inflammatory and antimicrobial properties of calendula help to calm and heal the skin, making it perfect for those with eczema, psoriasis, or other skin conditions. The vibrant yellow petals also add a beautiful, natural color to the soap.

Calendula Salve

Calendula salve is a healing balm that can be used to treat minor cuts, scrapes, burns, and insect bites. To make a calendula salve, the petals are infused into a carrier oil, such as olive or coconut oil, and then mixed with beeswax to create a solid balm. The salve harnesses the skin-soothing and healing properties of calendula, promoting faster healing and reducing inflammation. It’s a wonderful addition to any natural first aid kit.

By incorporating calendula into your soap and salves, you can enjoy its numerous skin benefits and create natural, healing products that are both effective and beautiful.
