Indeed very healthy... we used to have 2.5 acres of hilly land with 300 avocado trees in Spain. It came with the property we bought that we renovated. It was fun to grow avocados in the beginning, we built a huge water tank of 100k liters capacity. The problem was we were not always in Spain as our stay there was just 6 months during the winter season. We had an automated irrigation combined with a fertilizer tool. We hired our neighbor to take care of the property. Having the plantation on a hilly plot is not easy, the costs to run didn't pay ..the labor was expensive, water is costly in Spain and besides, the job to control pipe leakage, prune the trees and cleaning the weeds were backbreaking job. We sold the property after 8 years of running it.. it was a very good experience, but we'd rather be enjoying the andalucian sun as retirees for health reasons.
