The pistachio tree is native to Asia’s middle east and central regions. In various parts of the globe, the seeds of these plants are known as pistachio or pista. Pistachio is a tasty and healthy dry fruit that is eaten as a dry snack. They may also be used as a crunchy component in a variety of cuisines.

A bag of pistachios, on the other hand, is rather expensive. Growing pistachio trees might be a wonderful alternative if you are desiring this nutritious and sweet dry fruit. A fully developed pistachio tree may yield 20-50 pounds of pistachios, which can be stored for up to a year. As a result, you will not have to spend a high amount for pistachios.

What You Should Know About Pistachio Trees

It’s fascinating to note that these trees come in 11 different species, yet only Pistacia vera is commercially farmed. Let’s have a look at some of the basics of Pistachio trees before learning how to develop and care for them. Pistachio is a common name for a variety of nuts. Pistacia vera (scientific/botanical name) Well-drained, loamy, sandy, light soil Full exposure to the sun Spring is when the flowers bloom. Color of flower: reddish-brown Toxicity: Horses are poisoned. Oblique-banded leafroller, Soft scales, Mealybug, Citrus flat mite, and Navel orangeworm are all common pests.

What is the best way to grow a pistachio tree?

Pistachio trees are native to sunny climes and are best grown in full sunshine. The fruits and flowers are produced in clusters on these deciduous trees with compound leaves. Pistachio trees may grow to be 20-30 feet tall when fully grown, however they can be pruned to a more manageable size.

Although these trees may be grown from seeds in your home, it is usually preferable to cultivate them from plants purchased from nurseries. Nursery plants are best for growing these plants and getting proper nuts, while trees developed from kitchen seeds may not even yield fruit.

Pistachio trees blossom in the spring, mature in the summer, and are harvested in the autumn. During the winter, these trees are dormant. Keep in mind that these trees are alternating bearing, which means they will produce a large fruit one year and a smaller yield the next.


Deep, light, loamy, and well-drained soil is ideal for growing these trees. These trees may also be grown in soil with a high proportion of calcium carbonate (CaCO3). Pistachio plants benefit from high salinity.


Then there’s the weather. When it comes to establishing and developing pistachio plants, the climate is critical. Because these trees are native to hot, dry, and hot climates, they need lengthy, dry, and hot summers. As a result, daytime temperatures exceeding 100 degrees F (38 degrees C) are optimum for the growth of these trees.

These trees can also withstand temperatures of 45 degrees F (7 degrees C) in the winter. They cannot, however, endure high elevations or frozen ground. As a result, the dry climate is perfect for the development of pistachio trees.

Pistachio blooms are wind-pollinated, thus spring and summer breezes are also required for pollination.


So, when can you anticipate your pistachio trees to start producing fruit? It takes time; patience is required.

Pistachio trees require a long time to yield nuts. It’s possible that the first excellent yield of pistachios will take 7–8 years. After 15 to 20 years of planting, peak productivity occurs.

What if you want to grow pistachio trees in your garden or backyard?

You certainly may, but if you want to plant numerous plants, you’ll need a larger plot, since each pistachio tree should be spaced at least 20 feet apart. Overcrowding may occur if the length is less than 20 feet, and too much shadowing can degrade product quality.

In addition, since pollen is transferred by the wind from male trees to female trees, 1 male tree for every 8-10 female trees is planted.

Pistachio Tree Maintenance

While you’re thinking about the elements that influence pistachio tree planting, we recommend that you also think about how to care for these plants.

Pistachio tree maintenance, on the other hand, is rather simple. The tough part is waiting for them to bear fruit. These trees, on the other hand, are low-maintenance and simple to plant at home.

Let us concentrate on how we can care for pistachio plants as they develop.


Pistachio trees need at least 6 hours of direct sunshine every day, as previously indicated. They can’t handle dampness and need a dry, sunny environment.

Because these trees are tolerant of the desert, providing them with excellent and highly high sunny regions is critical. However, these trees are not suitable for everyone. If you reside in a location with a lot of humidity or damp soil, you may have to abandon your plans to plant pistachio trees.


Drought tolerance is a feature of pistachio trees. As a result, they cannot tolerate moist soil or regions with stagnant water. However, don’t let this reputation fool you into thinking you can skip watering them since they need a lot of it to produce high-quality nuts.

During the dry season, you must water these trees early in the morning, and heavy irrigation is necessary every 1- 2 weeks. In addition, drip watering is best for pistachio plants.


We all know that fertilizers are a tree’s greatest friend when it comes to preventing insect problems. When it comes to pistachio trees, feeding them once a year in late winter or early spring is adequate.

However, before using any fertilizer, we recommend doing a soil test to see what your soil may be lacking. In the ground, we also advocate using slow-release fertilizers, decomposed manure, and bone meal.


Pistachio trees are tall, as we’ve previously said. As a result, you might consider trimming to control their growth. Furthermore, since pistachio trees are dormant throughout the winter, trimming is most efficient at this time.

Pistachio trees should be pruned by selecting three major branches and then trimming the branches below the lowest (height) main branch. The lowest main branch should be 24 to 32 inches above the ground, with clipped branches ranging from 3 to 4 inches in length.

Fruits are produced on branches that are at least a year old, therefore avoid cutting the older branches. Pruning should be done twice or three times a year to support continued development.

It’s better to let all of the leaves and fruits fall naturally over the autumn and winter months. If they don’t, you’ll need to get rid of them to avoid spreading unhealthy plant material throughout the growth season.

Grafting may be used to grow pistachio plants. To achieve the optimum results, propagation should be done in the autumn. Budding onto rootstock is used for propagation.

Rootstock grown for commercial reasons, on the other hand, is a different story. Pistacia altantica and Pistacia integerrima are the two most frequent species for this purpose. Although propagating pistachio plants might be difficult, if you succeed, you can expect excellent yields.

Peters (female cultivar) and Kerman (male cultivar) are the two most prevalent cultivars (female cultivar).

Obtaining and Keeping

Harvesting pistachios is similar to upkeep in that it is rather simple. You may consume them right away or keep them in the fridge for later use.

Harvest your pistachios when the hull becomes reddish and cracks to show the shell underneath. Pistachios may be harvested by placing a tarp beneath the tree and shaking it until all of the nuts fall onto the tarp.

Remember not to let the pistachios fall to the ground since they will split before being harvested, increasing the risk of infection. To minimize shell stains and mold formation, remove the hull as soon as possible after harvesting. The drying process is also accelerated by the removal of the hull.

When it comes to storage, dried pistachios should be kept in an airtight container. The freshly collected nuts may be swiftly dried in the sun for 3-4 days or in an oven at 150-160°F for 11-13 hours.

Common Illnesses

Pistachio trees may get Alternaria Late Blight disease if they are exposed to too much humidity or moisture. Foliage lesions may grow black spores with this disease.

Other Common Illnesses include Botrytis, which develops in wet spring, mainly for male trees, Verticillium wilt, and Phytophthora. The most deadly among these is Verticillium, as this disease has no cure and can cause the trees’ death.

Pistachio Trees in Containers

If you want to cultivate your pistachio tree in a pot, you may do so. As a seedling, you may grow your pistachio tree in a container or pot for the first three to five years. After that, you’ll need to put them in the garden to provide them with well-drained, loamy soil in which to flourish.

However, if you’re growing your pistachio tree in a pot, remember to re-pot it in a bigger container every year to allow the roots more space to develop.

Tips to Consider while Growing and Pistachio Tree Maintenances

  • To cultivate these plants economically, it is preferable to purchase pistachio seedlings.
  • Always prune your trees using clean, sharp pruning tools.
  • If you want to plant a lot of pistachio trees, you should test your soil beforehand.
  • Ideally, the soil pH should be between 7.0 and 7.8.
  • Prepare the soil by chiseling, sowing, and disking it before planting the saplings or raw seeds.
  • The process of budding should be continued in the autumn.
  • The male-to-female plant ratio should be 1:8 or 1:10, depending on the situation.
  • During the rainy season, do not water the plants.
  • Water logging should be avoided at all costs.
  • Pistachio plants may benefit from nitrogen fertilizers.

Last but not least!

The final line is that you can plant a pistachio tree in your home or garden. These trees are easy to care for and yield tasty and healthy nuts.

However, if you have decided to produce them on your own, you must consider the variables and advice listed above. Above all, have the patience to wait for the first batch of pistachio nuts, also known as pistas.

We recommend purchasing and planting pistachio seedlings from a nursery if you want to ensure fruit production. However, keep in mind that these trees should be planted at a minimum of 20 feet apart to allow them to develop and branch out properly.


Q. How do you know if a pistachio tree is male or female?

Ans. A male pistachio tree is usually taller and has 2 to 3 inch long clustered branches. A female pistachio tree, on the other hand, has open and loose branches that are 6 to 8 inches long.

Q. What climate is best for growing pistachio trees?

Pistachio trees thrive in hot, dry environments. These trees need at least 38°C during the summer, and roughly 1,000 hours below 7°C during the winter.

Q. How long do pistachio plants take to produce nuts?

Ans. It takes around 5-7 years for a pistachio tree to produce its first crop of nuts. However, the highest output will occur after 15 to 20 years after planting.

Q. What is the maximum height of a pistachio tree?

Ans. A fully established pistachio tree may reach a height of 20-30 feet.

Q. What is the maximum number of nuts you can receive from a single yield?

The environment, crop management, and cultivar all have a role in pistachio yields. Nonetheless, you may anticipate a 7- 10 kilogram yield per fully developed tree on average (after 10- 12 years of budding).
