Jojoba prefers light, coarsely textured soils. Good drainage and water penetration is necessary. It tolerates salinity and nutrient-poor soils. Soil pH should be between 5 and 8. High temperatures are tolerated by jojoba, but frost can damage or kill plants. Requirements are minimal, so jojoba plants do not need intensive cultivation. Weed problems only occur during the first two years after planting and there is little damage by insects. Supplemental irrigation could maximize production where rainfall is less than 400 mm. There is no need for high fertilisation, but, especially in the first year, nitrogen increases growth. Jojoba is normally harvested by hand because seeds do not all mature in the same time. Yield is around 3.5 t/ha depending on the age of the plantation.
