Marigolds are colorful and vibrant flowers that are highly popular among gardeners. Also known by their scientific name Tagetes, these plants belong to the family Asteraceae. They are native to the Americas, specifically Mexico and Central America, and have a rich history dating back to ancient times. Some scholars believe the name “Marigold” originated as a way to honor the Virgin Mary. Marigolds have become a staple in gardens and landscapes because of their cheerful appearance, distinct scent, and ease of care.
Our Selection of Marigolds
At Martin Garden Center, we carry both African and French Marigolds in flats, beginning in April. Usually, these flats are gone before mid-May. Any 4-packs that remain in June, which happens rarely, are potted up to 4″ containers. Marigold seeds are also available of other varieties.
The African marigold (Tagetes erecta) is known for its large, double flowers that can reach up to 4 inches in diameter. African marigolds are often used in flower beds, providing a burst of color, and can bloom throughout the summer and fall. We carry the African Marigolds in Vanilla, Yellow, Orange and mixed flats.
Another popular species is the French marigold (Tagetes patula), which has smaller, single, or double flowers and a more compact growth habit. The French varieties we carry include the Bonanza series and the Durango Series in all colors and combinations.
Growing and Caring For Marigolds
- Planting: Marigolds prefer well-draining soil with a slightly acidic to neutral pH. Start seeds indoors about 6-8 weeks before the last expected frost, or sow them directly in the garden after the danger of frost has passed. Space the plants according to their specific variety, providing enough room for air circulation.
- Sunlight: These sun-loving plants thrive in bright, direct light. Plant them in a location that receives at least 6 to 8 hours of direct sunlight daily to produce their vibrant and prolific blooms.
- Soil: Marigolds are adaptable to different soil types but flourish in well-draining soil with good fertility. Amending the soil with compost or organic matter before planting can provide the nutrients needed for healthy growth and flowering.
- Watering: While they are relatively drought-tolerant once established, Marigolds benefit from consistent moisture during the growing season. Water them at the base to prevent fungal issues and avoid overhead watering, which can lead to foliage diseases. Allow the soil to dry between watering to prevent root rot.
- Fertilizing: Marigolds are not heavy feeders, but a balanced, all-purpose fertilizer applied at planting and then again during the growing season can enhance their performance. Avoid excessive nitrogen, as it may result in lush foliage at the expense of flowers.
- Pruning and Deadheading: Regular deadheading and pruning encourage continuous blooming and prevent the formation of seeds. Prune leggy or damaged stems to promote bushier growth. Pinch off the tips of young plants when they reach about 4-6 inches in height.
- Pest Control: Marigolds are known for their pest-repelling properties due in part to their strong-smelling foliage and because they naturally produce pyrethrum, which is an insecticide. This makes them popular for companion planting. However, they may still face challenges like thrip or spider mites. Inspect plants regularly and address pest issues promptly to ensure the health and longevity of your marigold garden. Note that in many vegetable gardens, Marigolds are used as sacrificial plants to draw thrip and spider mites away from the food.
Leaves and Flowers
Marigold leaves exhibit a distinct and finely divided structure, showcasing their feathery appearance. The foliage of marigolds is typically dark green and pinnate, with serrated edges along the leaflets. The leaves are arranged oppositely along the stems, creating a lush and symmetrical overall plant structure.
Marigold flowers are the highlight of these plants, boasting vibrant and warm colors that range from shades of gold and orange to yellow and red. The flower heads are typically composed of dense clusters of small, tubular disc flowers surrounded by prominent ray petals, creating a distinct daisy-like appearance. Their unique coloration and shape make them popular in gardens and floral arrangements.
Uses in the Garden
Marigolds are prized for their ornamental value, and their vibrant colors can add a cheerful and lively ambiance to any garden. Whether planted in borders, containers, or as part of mixed flower beds, marigolds contribute to the landscape’s visual appeal. Marigolds are also frequently used in cut flower arrangements, bringing their bright and distinctive blooms indoors to enhance the beauty of bouquets and floral displays.
Marigolds are often strategically used in companion planting to benefit neighboring plants. The roots of Marigold plants release compounds that deter nematodes, microscopic soil-dwelling pests that can damage the roots of many plants. The strong aroma of marigold foliage helps repel insects like mosquitoes and whiteflies. Certain varieties of marigolds, such as French marigolds, are known to deter pests like aphids and tomato hornworms when planted near tomatoes. And, yellow and lighter cream/vanilla-colored Marigolds are often used as sacrificial plants for thrip. Marigold’s vibrant flowers can also attract pollinators like bees and butterflies, promoting overall biodiversity in the garden.
Frequently Asked Questions
Are Marigolds Perennials or Annuals?
Marigolds are typically grown as annuals, meaning they complete their life cycle within one growing season. However, some varieties may exhibit perennial characteristics in certain climates.
Are Marigolds Edible?
Some Marigolds varieties are edible and cultivated for culinary purposes. Marigolds are often a colorful and flavorful addition to salads, soups, and other dishes. Not all marigold varieties are suitable for consumption, so make sure to choose edible varieties specifically grown for culinary use.
Do Deer Eat Marigolds?
Marigolds are deer-resistant; deer typically avoid feeding on them. Marigolds’ strong scent and bitter taste deter deer, making them less likely to browse on these plants. While no plant can be guaranteed to be entirely deer-proof, marigolds are commonly chosen for gardens in areas with deer populations.
Are Marigolds Pest Resistant?
Marigolds are known for repelling certain insects due to natural compounds in their foliage. The most commonly mentioned benefit is their ability to deter nematodes, a type of soil-dwelling pest that can damage plant roots. Marigolds produce compounds, such as thiophenes and terpenes, that have been found to have nematode-repelling properties.
