Edible uses

There are no edible uses listed for Tagetes micrantha.

Material uses

Many members of this genus are widely used in companion planting schemes[1]. Secretions from the roots of growing plants have an insecticidal effect on the soil, effective against nematodes and to some extent against keeled slugs. These secretions are produced about 3 - 4 months after sowing[2]. These root secretions also have a herbicidal effect, inhibiting the growth of certain plants growing nearby. It has been found effective against perennial weeds such as Ranunculus ficaria (Celandine), Aegopodium podagraria Ground elder), Glechoma hederacea (Ground ivy), Agropyron repens (Couch grass) and Convolvulus arvensis (Field bindweed)[2][1].

An essential oil distilled from the leaves and flowering stems, harvested when the plant is forming seeds, is used as an insect repellent[3][4]. It is also used in perfumery[1].

Dried plants can be hung indoors as an insect repellent[1].

Cultivation

Requires a well-drained moderately fertile soil in a sunny position[2].

Plants are not very resistant to frosts and need to be grown as half hardy annuals. Removing dead flowers before the seed is formed will extend the flowering season[6]. Most members of this genus are very good companion plants, see 'Other Uses' below for more details[1].

Plants are prone to slugs, snails and botrytis[6].
