What climate do macadamias grow in?

A general recommendation is for periodic application of 8:10:5 NPK ratio fertilizer. Use one pound of fertilizer for every year of a tree’s life, but don’t exceed 10 pounds per tree. Grow green manure crops, such as clover, between orchard rows to improve nutrient availability.
Are macadamia trees self pollinating?
