About this plant
Pistacia vera, commonly known as pistachio, is a small tree famous for its edible nuts. It has pinnate leaves and produces clusters of small flowers, followed by greenish nuts that mature to a beige shell with a tasty seed inside. Pistachios are widely enjoyed as snacks and used in cooking and desserts. The tree is valued for its drought tolerance and ability to grow in warm climates.

Watering. Water deeply but infrequently, allowing soil to dry between watering. Reduce watering in winter when the tree is dormant.
Fertilizing. Apply a balanced fertilizer in early spring before new growth begins. Additional feeding during the growing season can support nut production, but avoid over-fertilizing, which can harm the tree.
Pistachio trees are hardy and drought-tolerant but need full sun and well-drained soil to thrive. They require patience, as they take several years to start producing nuts. Regular watering during dry periods and occasional fertilizing help maintain healthy growth.

Toxicity & Safety
Pistachio nuts are safe to eat for most people but can cause allergic reactions in sensitive individuals. The tree's sap may cause mild skin irritation in some.
Allergy information
Pistacia vera, or pistachio, can cause allergic reactions in some people, especially those sensitive to tree nuts. The main trigger is the nut itself, which can cause symptoms like itching, swelling, or more severe reactions. To reduce exposure, avoid eating pistachios if you have nut allergies and be cautious around the tree during harvest.
Common problems
Pistachio trees may suffer from fungal diseases if overwatered or planted in poorly drained soil. Pests like aphids or mites can also affect them. Lack of sunlight or poor soil can reduce nut production.
Uses
Primarily grown for its edible nuts, pistachio is also used as an ornamental tree in warm climates and for shade.
Notes
Prune pistachio trees in late winter to maintain shape and remove dead wood. They require patience as they may take 5-7 years to produce nuts. Protect young trees from frost and strong winds.
