Marigold is a genus of about 50 species of annual herbs native to southwestern North America, tropical America, and South America. Several species are grown as garden ornamentals for their attractive flowers, and most marigolds have strong-scented leaves. The bright yellow-orange to red inflorescence of composite flowers is the most distinguishing characteristic of the flowering herb. Marigold scientifically known as Tagetes erecta L. is an herbaceous plant belonging to Aster family (Asteraceae ⁄ Compositae), cultivated commercially for its yellow flowers, both as an ornamental plant and as a source of feed pigments and food coloring additives. The plant is native to Central America, Mexico and Guatemala.
Here are some step-by-step instructions for taking care of marigolds: Planting: Marigolds can be grown from seeds or purchased as seedlings. They prefer full sun and well-draining soil. Water them regularly, keeping the soil evenly moist but not waterlogged. Watering: Marigolds require regular watering throughout the growing season (spring to fall). They need at least an inch or two of water every seven to ten days. If the rain doesn’t provide it, you should. Fertilizing: To stay healthy during the months-long blooming marathon, marigolds need a dose of diluted liquid fertilizer, provided once every month or so while they’re flowering. Select a balanced product (10-10-10 NPK). Pruning: Prune marigolds regularly to encourage bushy growth and more flowers. Deadheading spent blooms is also important to keep the plant looking tidy and to encourage more blooms. Propagation: Marigolds can be propagated by stem cuttings taken in late summer or early fall. Trim off a healthy portion of stem that’s around 6 inches long. Opt for a green, supple stem over one that’s older and… Remove foliage from the bottom half of the stem. Dip the cut end in rooting hormone. Plant the stem in a small container filled with moistened soilless potting mix.
