Growing Artemisia is not simple. That is why certain conditions are required to start growing successfully

Cultivation site

Do not cultivate in areas contaminated by hazardous substances (heavy metals, agrochemicals and other industrial waste). Avoid any risk of soil, air or water pollution. Evaluate the impact of past land use on the chosen cultivation site (previous plantations and, in particular, any possible applications of phytosanitary products) [1].

Access to water

Growing Artemisia annua requires a significant amount of water since each plant must be watered generously morning and evening during the dry season. The amount of water must be reduced according to rainfall during the rainy season.

Excess water is also to be avoided! This can induce leaching of nutrients or reduction in root depth of the plant [2].
Moreover, Artemisia annua is sensitive to waterlogging. For this reason, drainage channels must be provided when growing Artemisia annua during the rainy season [3].

It’s important to reduce the physical impact of water on fragile seedlings to avoid destroying them [5].

Do not cultivate next to plants requiring chemical treatments!

It is vital to use only non-toxic cultivation techniques because species of the genus Artemisia are powerful bio-accumulators! [8] ie, they absorb and accumulate heavy metals (Cr, Ni, Co, Fe, Mn, Cu, Zn), chemical elements and radioactive waste.
