FAQ: Frequently Asked Questions About Marigold Care

If marigolds are native to Mexico, why are some called French marigolds or African marigolds? Marigold seeds were brought to Europe from Mexico in the 16th century. French marigolds were developed by French plant breeders, while African marigolds arrived in Europe through trading routes that passed through Northern Africa.
Do marigolds really protect vegetables from insects? Marigolds have a reputation for repelling insects, but studies show the evidence is dubious—with one exception. There is some evidence that marigolds emit a soil chemical through the roots that can help control damaging nematodes. The powerful smell of marigolds does seem to be repugnant to deer and rabbits.
Are marigolds edible? Signet marigolds are often used in salads. The flower petals, chopped and mixed with salad greens, add interesting color and a slightly spicy taste. The other types of marigolds are not considered edible.
What is a pot marigold? Pot marigold (Calendula officinalis) is a flower species belonging to an entirely different genus from true marigolds, though it is in the same Asteraceae family. Its flowers resemble those of marigolds or chrysanthemums, but the foliage is much different, lacking the ferny texture.
What are the common landscape uses for marigolds? Marigolds make nice border plants, but their hot colors should be used with discretion. They work best with either other hot colors, like yellow and orange daylilies, or with complementary purples, like salvia and verbena. Because most varieties are short plants, marigolds are generally used in the front of a border or in containers. Taller African marigolds, however, are often planted in clumps near the back of the border garden.
How often should I water my marigolds? Water regularly when first planting seeds or seedlings. Once established, water weekly, adjusting based on weather conditions.
Do marigolds need fertilizer? Marigolds generally do not require supplemental fertilizer unless the soil is exceptionally poor.
How do I encourage my marigolds to bloom more? Ensure plants receive plenty of direct sunlight, regularly deadhead spent flowers, and avoid over-fertilizing.
What are some common pests that affect marigolds? Snails, slugs, and aphids are common pests that can affect marigolds.
How can I prevent powdery mildew on my marigolds? Ensure good air circulation, water at ground level, and avoid overhead spraying to prevent powdery mildew.
