Plant care & info
Family: Asteraceae
Genus: Tagetes
Origin: Mexico and Central America
Marigold are a classic summer blooming annual in our region. Marigolds need full sun (6-8 hours a day), average to well-drained soil and regular watering to thrive.
Plant marigold seedlings about 6”-12” apart depending on variety, adding compost to the area if the ground is particularly dense or nutrient depleted.
Apply a favorite flower fertilizer as directed throughout spring and summer to keep Tagetes performing at their best.
As they mature, overhead watering can cause branch breakage, especially with taller and larger-bloomed varieties, so opt for watering at the base of plant instead. The flowering period can extend to frost if withered blooms are removed regularly.
Tagetes seeds germinate quickly – often in less than a week in warm, moist soil. Once seedlings appear, these plants grow rapidly and are typically ready to bloom in 45 to 50 days.
Many gardeners start marigold seeds indoors in trays or pots of soil six to eight weeks before the last expected frost in their location, so they will be ready to bloom in late spring when moved outside.
Seedlings grow quickly and require little care other than watering and occasional pinching to force dense compact foliage. In general, Tagetes adjust quickly to transplanting and resume growing almost immediately as long as the soil is moist.
Tagetes seeds can also be directly sown in the soil in the spring as soon as the danger of frost passes, but keep in mind they will not produce blooms for nearly eight weeks.
Many gardeners prefer to save their own seed from marigolds by allowing the final flush of blooms to ‘go to seed’ on the plant. It should be noted, however, that hybrid seeds will not reproduce true to the parent plant and some may fail to germinate. Saving your own seed comes with some risk, but even hybrid seeds may produce interesting varieties in color, shape or size.
Tagetes are fairly pest and disease resistant, however young plants are susceptible to slugs, snails and botrytis.
A note on companion planting and insecticidal properties: The roots of certain Tagetes species have been found to exude a substance that minimizes soil borne pests (such as certain nematodes), but only after being established for at least three months.
These lovely flowers attract beneficial pollinators, are edible, can be used to make natural dyes, and in the case of specific species, have insecticidal properties that make them a favorite for companion planting in the vegetable garden.
Add Color To Your Garden With Annuals
Annuals are planted every year and provide color summer till frost. Many annuals can be wintered over indoors or reseed outdoors providing extra value to their flower power!
