Calendula (Calendula officinalis), also known as pot marigold, is a cheerful flower famed for its powerful healing properties. Easily grown in gardens or pots, Calendula offers soothing skin remedies, boosts immunity, and brightens your herbal collection. Discover how you can cultivate and use this versatile herbal beauty right at home.
Fun Fact: Calendula’s nickname, “pot marigold,” comes from its historic use in cooking—flower petals were traditionally added to soups and stews.

Easy Tips for Planting Calendula

Calendula (Calendula officinalis), also known as pot marigold, is one of the easiest and most rewarding herbs to grow. Its bright golden-orange blooms aren’t just beautiful—they’re also medicinal powerhouses, prized for their skin-soothing, anti-inflammatory, and wound-healing properties. Whether you’re growing calendula for skincare remedies, tea, or pollinator appeal, it thrives with minimal effort in most climates.

Plant Type & Zones

Calendula is a hardy annual that adapts well to a wide range of environments, growing successfully in USDA Zones 2–11. In cooler climates, it blooms spring through fall; in warmer regions, it may slow or rest during peak summer heat but reblooms in cooler months.

Sunlight Requirements

Calendula prefers full sun (at least 6 hours per day) for the most abundant and vibrant flowers, though it can tolerate partial shade in hot climates. A little afternoon shade helps prevent wilting during summer heat waves.

Soil Preparation

Plant calendula in well-draining, moderately fertile soil. It isn’t picky and performs well even in average garden soil. Avoid overly rich soil, which can lead to excessive foliage and fewer blooms. Lightly amend with compost before planting to encourage steady growth.

Propagation & Planting

Direct-sow seeds outdoors in early spring as soon as the soil can be worked, or in fall in mild climates for early blooms. Sow seeds about ¼ inch deep and lightly cover with soil. Keep the soil moist until germination, which typically occurs in 7–10 days. Thin seedlings to 8–12 inches apart once they reach a few inches tall to give plants room to breathe and branch out.

Watering & Care

Calendula enjoys consistent moisture but dislikes soggy soil. Water at the base to keep leaves dry and reduce fungal issues. Deadhead (remove spent blooms) regularly to extend flowering. Occasional light pruning can also encourage fresh growth and continuous blooming.

Gardener’s Tip

Continuous sowing is the secret to keeping your calendula patch blooming all season long! Plant new seeds every 2–3 weeks for overlapping waves of flowers. Not only will this ensure a steady supply for teas, tinctures, or salves, but it also attracts pollinators and brightens the garden year-round.

Caring for Your Calendula Plants

Calendula is a resilient, low-maintenance herb that rewards even minimal care with an abundance of cheerful, healing blooms. Once established, it will flower prolifically from early summer through late autumn, making it a favorite for both herbalists and home gardeners. With just a few simple steps, you can keep your calendula patch thriving and productive season after season.

Watering

Calendula prefers moderate watering. Keep the soil evenly moist, especially during dry spells, but avoid overwatering or allowing water to pool around the roots. Overly wet soil can cause mildew or root rot. Water early in the morning at the base of the plant to prevent fungal issues and encourage strong root growth.

Feeding

This flower is not a heavy feeder. A light compost addition at planting usually provides all the nutrients calendula needs. Too much fertilizer encourages lush foliage instead of flowers. If growth slows midseason, you can refresh the soil with a thin layer of compost or worm castings.

Blooming Period

Calendula blooms continuously from early summer to late autumn, especially if flowers are harvested or deadheaded regularly. The more you pick, the more blooms you’ll get. These flowers are ideal for cutting, drying, or making into herbal skincare preparations.

Maintenance

Deadhead spent flowers to promote ongoing blooms and prevent self-seeding (unless you want calendula to reseed naturally). Trim back leggy growth to stimulate new branches. Calendula is self-sufficient, but regular care keeps it looking lush and full.

Gardener’s Tip

Calendula is a natural pest repellent—its scent helps deter aphids, nematodes, and other common garden pests. Plant it among vegetables like tomatoes, carrots, and beans to protect your edible crops while attracting pollinators and beneficial insects.

Active Compounds & Benefits

Calendula’s healing power comes from its high concentration of flavonoids and triterpenoids—potent anti-inflammatory and antimicrobial compounds that calm irritation, promote skin repair, and boost immunity. These active ingredients make calendula a staple in natural remedies for burns, cuts, eczema, and other skin conditions.

Pro Tip

Harvest flowers in the late morning after dew dries for the highest resin content. Dry them in a cool, dark place and store in airtight containers for year-round use in teas, oils, and salves.

Gardener’s Tip: Calendula naturally repels pests—plant it among vegetables to protect your edible garden.
