T. minuta is a vigorous, erect, half-hardy annual with edible, pinnate leaves divided into linear or narrowly lance-shaped, toothed, mid- to dark green leaflets and clusters of tiny, light yellow flowers in summer. A miniature marigold (Tagetes minuta) is a warm-season annual with a long flowering season. It works well as edgings for walkways, flower beds, borders and window boxes, growing less than 12 inches tall. These bright-colored summer flowers are planted 6 to 12 inches apart in a sunny location with enriched soil. Miniature marigolds grow smaller versions of larger types with just a little care.
Established marigolds in garden beds need a good soak once each week. give them enough water so that the soil is moist to a depth of 6 to 8 inches (15-20cm) if the weather is unusually hot or windy, they'll need extra water.
Liquid fertilizers are applied more frequently, bi-weekly or monthly, for example. Granular products are used less frequently, perhaps once every month or two. Slow-release houseplant fertilizers break down slowly and release their nutrients in small amounts, over a longer period of time. A single application of most of these products lasts for three to four months.
