Frequently Asked Questions

u

What is the ideal root depth for pistachio trees?

The average root depth of a mature pistachio tree is around 10 feet (3 meters), but the roots can spread even wider, up to 26 feet (8 meters).

u

How do pistachio trees flower?

Pistachio trees produce small, inconspicuous flowers that are crucial for the pollination process. Male and female flowers are found on separate trees.

u

Do pistachio trees require a pollinator?

Yes, pistachio trees need a pollinator. Pollen from male trees is transferred to female trees primarily by wind, though artificial pollination can also be used.

u

When is the best time to harvest pistachios?

Harvesting typically begins in late summer, from August to mid-September, depending on the variety and region. The process can take 15 to 20 days.

u

How are pistachios harvested?

Pistachios can be harvested manually by shaking the trees or using mechanical shakers. The fruits are collected on nets or directly into bins for sorting and processing.

u

What are common pests and diseases affecting pistachio trees?

Common issues include Verticillium wilt, Phytophthora root rot, and Armillaria root rot. Proper soil management and resistant rootstocks can help mitigate these problems.

u

How long does it take for a pistachio tree to bear fruit?

Pistachio trees usually start bearing fruit in their fourth or fifth year, with full production achieved around 12 to 14 years of age.

u

What is the average yield of a mature pistachio tree?

A mature pistachio tree can produce up to 33 lbs (15 kg) of dry nuts or 83 lbs (37.5 kg) of fresh harvested fruits annually.

u

How should pistachios be stored after harvesting?

After harvesting, pistachios should be peeled and dried within 10-12 hours to maintain quality. They should be stored in a cool, dry place.

Harvesting Pistachios

The Labor-Intensive Process of Pistachio Harvesting

Harvesting pistachios is a meticulous and labor-intensive process. It begins with shaking the trees, either manually or using mechanical shakers, to collect the fruits. The pistachios are then gathered on nets or directly into bins. This is followed by a thorough sorting process to remove leaves, broken seeds, and other debris. Within 10-12 hours of harvesting, the nuts must be peeled to prevent quality deterioration. In large orchards, the harvested fruits are quickly transported to processing units, ensuring the nuts are processed within a few hours to maintain their freshness and quality.

Common Diseases and Pests in Pistachio Orchards

Verticillium Wilt: This soil-borne fungal disease can severely impact pistachio trees by blocking water and nutrient flow, leading to the collapse of branches. It is caused by the pathogen Verticillium dahliae and can persist in soil for many years.

Phytophthora Root Rot: This disease weakens the roots, hindering the tree’s ability to transport water and nutrients. It thrives in heavy, waterlogged soils and can cause slow growth, defoliation, and reduced fruit production.
