The pistachio plant is an incredible plant with a thousand qualities. The plants in Bronte are centuries old, even more than 300 years old.
The roots can even break through volcanic rock and go deep. There are female plants that make flowers and fruit and male plants that serve for pollination, both of which are indispensable.  

When do you prune Pistachios?

Pistachio pruning is an essential practice to ensure good fruit production and keep the plant in a proper shape to facilitate harvesting.
Pistachio plants are kept low, and with pruning they maintain a loose canopy.
The ideal period for pruning pistachios is during the end of winter and the beginning of spring, usually between February and March. At this stage, the tree is still in a state of vegetative rest, which reduces the stress caused by pruning and allows a quick recovery with the arrival of spring.

How to Prune Pistachios?

1. Remove Dry and Diseased BranchesThis is essential to prevent diseases and pests.
2. Thinning the Hair: Ensuring good air circulation within the foliage helps reduce the risk of fungal diseases.
3. Check HeightMaintain a manageable height to facilitate harvesting and other cultivation operations.

When Does the Pistachio Blossom?

Pistachio blossoming is a crucial time for future fruit production. Pistachios blossom in spring, usually between April and May, depending on weather conditions. Flowering occurs after pruning, when temperatures start to rise.
We recognise the flowers of male plants because they are reddish in colour and the flowers are more dense, unlike female plants, which have flowers that are almost white in colour.

Factors Influencing Flowering

• ClimateMild temperatures and sunny days favour good flowering.
• Irrigation: An adequate water supply during the sprouting phase is essential.
• NutritionMake sure the soil is well fertilised before flowering.

When Do Pistachios Ripen?

Pistachio ripening occurs several months after flowering, usually between late August and September. During this period, the fruit begins to swell when the outer husk (the soft part) turns white and pink, the pistachio is ready for harvest.

Signs of Maturation

• Colour Change: The outer shell changes colour from green to yellow or reddish/white.
• Fruit ConsistencyMature pistachios are crunchy and fill the shell.

When is the Pistachio Harvested?

The pistachio harvest is the culmination of two years of care and attention. It occurs every two years, usually in odd-numbered years the harvest is done and in even-numbered years the plant is allowed to rest.
The best time to harvest pistachios is September, when the fruits are fully ripe.
Harvesting must be done promptly to prevent the fruit from falling to the ground and spoiling.

Harvesting Techniques

In the case of the Bronte pistachio, harvesting is done entirely by hand. A bucket is used that is hung around the neck or a special sack where the pistachios are dropped inside.
