When harvesting is done in Pistachio?

Pistachio trees take longer time to produce nuts. These budded trees become ready to produce fruits for 5 years and will not reach maximum production until the 12th year of planting. Pistachio trees begin bearing the 5th year after budding. However, a significant crop is not harvested until the seventh or eight season. The first full production year starts occurring around 12th year only. The easy identification of maturity is when the hull separates easily from the shell. Generally, this period extends for 6 to 10 days. Care should be taken while harvesting by avoiding under developed kernels.
