Taxonomic Information

Appearance

Tagetes plants have dark green leaves and produce compact clusters of flowers that can range in size from 1 to 4 inches in diameter. The flowers are typically yellow, orange, or red and have a daisy-like shape with multiple layers of petals. Some varieties may also have a unique scent, which can range from sweet and floral to pungent and musky.

Care Guide

Tagetes plants are relatively easy to care for and can thrive in a variety of growing conditions. Here are some tips for keeping your Tagetes plants healthy and happy:

• Water: Water your Tagetes plants regularly, making sure that the soil stays moist but not waterlogged. During periods of drought, you may need to water more frequently to prevent the plants from wilting.
• Fertilization: Apply a balanced fertilizer every four to six weeks during the growing season to promote healthy growth and abundant blooms.
• Soil: Tagetes plants prefer well-draining soil that is rich in organic matter. If your soil is heavy or clay-like, consider adding compost or other organic matter to improve drainage and fertility.
• Sunlight: Tagetes plants require full sun to thrive, so be sure to plant them in a location that receives at least six hours of direct sunlight per day.
• Hardiness Zones: Tagetes plants are hardy in USDA zones 9-11 but can be grown as annuals in cooler climates.
