Growing a pistachio tree in your garden or in a pot: is it realistic?

It is one of the questions people search for most about pistachio trees: can I plant one at home? The honest answer comes in two parts. Yes, the tree will grow almost anywhere that doesn’t get a hard freeze. No, it won’t give you pistachios unless your summer is like a summer in the south of France.

Can you plant a pistachio tree anywhere in France?

There are two separate questions here: will the tree survive, and will it bear fruit?

As for survival, the true pistachio tree is hardier than people think. Gardening guides rate it hardy to −15 or −17 °C once established. Its weak points lie elsewhere: April frosts, which kill the flowers from −2.5 °C, and waterlogged soil in winter, which rots the roots.

To fruit, it needs something no shelter can provide: long hot, dry months from April to September to ripen the pistachios, and dry air to keep the leaves healthy.

In Normandy or Belgium, then, you can plant a pistachio tree for the pleasure of the tree, not for a harvest.

Do you need two pistachio trees to get pistachios?

Yes. This is the most common mistake in gardens. The pistachio tree carries its male and female flowers on separate trees: a female tree on its own will flower, but its shells stay empty.

• You need at least one male and one female. One male is enough for five to eight females.
• Plant them no more than 10 to 15 metres apart, with the male on the side the wind comes from: the wind carries the pollen, not bees.
• Both must flower at the same time. Ask the nursery for a male that matches your female variety.

Trees sold as “self-fertile” usually carry two grafts on the same rootstock, one male and one female. It is a good solution for a small garden, as long as you don’t cut off the male branch when pruning. We explain all this in our article on male and female pistachio trees.

When and how do you plant a pistachio tree in the ground?

Plant while the tree is dormant: from November to January for a bare-root tree, and up to March for a pot-grown one.

1. Choose the warmest spot in the garden, in full sun, away from hollows where water and cold air collect.
2. Check the drainage. Fill a hole 40 cm deep with water: if it is still there the next day, plant somewhere else, or on a mound. Pistachio trees like chalky, stony soils; they can’t cope with heavy clay or acid soil.
3. Leave enough room. A mature pistachio tree reaches 6 to 10 metres high. Allow 5 to 6 metres between trees.
4. Don’t bury the graft union, the swelling you can see at the base of the trunk, and stake the tree.
5. Water regularly for three summers. After that, the tree more or less looks after itself.

How long before the first pistachios?

Six to eight years for a grafted tree, in a climate that suits it. After that, it clearly bears in alternate years: a good crop, then a small one. That is its nature, and summer watering only softens the swing. There is more detail in our article on how long a pistachio tree takes to bear.

Can you grow a pistachio tree in a pot?

You can keep one alive in a pot. Getting it to fruit is another matter: gardening guides say it rarely fruits, and we have found no documented account of a harvest from a pot-grown tree.

If you want to try:

• use the biggest container you can, with drainage holes and a very free-draining growing medium;
• water regularly in summer, but never leave water standing in the saucer;
• leave the pot outside in winter unless there is a hard frost. The tree needs several hundred hours of cold to flower: overwintering it in a heated room deprives it of them;
• in very cold weather, protect the pot rather than the branches. In a container, the roots are the first to freeze. A cold greenhouse or an unheated garage will do.

Can you grow a pistachio tree from a pistachio?

Yes, on one condition: the pistachio must be raw. A roasted or salted pistachio is a dead seed, and that goes for almost every pistachio in a bag of snacks. You need unroasted pistachios, preferably still in their shells.

1. Soak the pistachios in water for several days, changing the water every day.
2. Sow them in a pot, in a light mix, 2 or 3 cm deep.
3. Leave the pot outside over winter: the cold breaks the seed’s dormancy.
4. Wait for spring. The success rate is low, so sow several.

Be aware of what you will get. A seedling tree is not grafted: it won’t be true to its mother’s variety, it is as likely to be male as female, and it will take longer to flower. It is a lovely thing to do with children. If you want a harvest, buy grafted trees.

Where can you buy a pistachio tree?

From a fruit-tree nursery in the south of France rather than a general garden centre. Three things should be on the label:

• the Latin name Pistacia vera. The mastic tree and the Chinese pistache are also sold as “pistachio trees”, and neither bears pistachios: see our article on how to tell them apart;
• the variety and the sex: a female, such as Kerman or Larnaka, and a male to go with it;
• the rootstock, which shows the tree has been properly grafted.
