Comparison of cold tolerance between coffee and macadamia nuts

An authoritative agronomic expert reminded me that when promoting shaded coffee trees, we should consider carefully. He found that the bark of macadamia nuts would burst after frost. In the course of my research in the countryside, I deliberately observed the performance of macadamia nuts and coffee in frost disasters.

I visited some fields where nuts and coffee were interplanted, and found that under the same temperature and planting environment, nuts are more resistant to cold. Coffee has been frozen to death, but macadamia nuts do no harm. I think macadamia nuts can be planted in coffee fields, because this can increase the income of coffee growers, but in the process of planting, we should pay attention to scientifically control the planting density.
