How do I propagate jojoba and get the right male to female plant ratio?

Jojoba is dioecious, meaning male and female flowers are on separate plants, and only female plants bear the seed you sell, so getting the planting material and ratio right is the single most important decision and a common reason past plantings failed. If you raise plants from seed you cannot tell the sex until they flower years later, which wastes land on unknown plants, so the better route for a serious planting is vegetative propagation from cuttings of identified, good yielding female clones plus a smaller proportion of selected male plants for pollination. A common approach is to keep only a modest share of plants as males, enough for good wind pollination, with the rest as proven females, but confirm the exact recommended ratio and clone choice with the arid research station. Buy planting material only from a reliable source that can guarantee the sex and clone, because poor unsexed material is exactly what disappointed earlier growers. Verify propagation method and ratio locally before planting, and start small to learn.
