Irrigation is applied daily in the first month and then every week in sandy soil and once in two to three weeks during the summer. Fertilizer is applied with the irrigation water, mainly nitrogen phosphate and potassium. The most serious problem in the two first years of the plantations are weeds. Timing of the first significant yields depends on the clone planted. Other clones may have harvestable yields on their fourth year.
Harvesting is done from the ground in late summer after most of the seeds have fallen onto the soil.
Seeds may be collected manually or by machines. Auxiliary equipment for the preparation of the soil, shaping of the bushes and other operations related to harvest is also available. The problem of pruning of young plantations grown from cuttings has still not been solved. It has been found that during the propagation of cuttings the dominant phytopathological problems in the nursery are caused by two species of Fusarium, F. solani and F. oxysporum . In jojoba plants in plantations, the major problems are infection by F. oxysporum and but also by F. solani .
