Mastic Tree

In short: The mastic tree (Pistacia lentiscus var. Chia) is a unique evergreen. The species grows across the Mediterranean, but only the variety in southern Chios, Greece yields the prized resin known as mastic gum — the “tears of Chios”.

What is a mastic tree?

The mastic tree, known in Greek as Σχίνος (schinos), belongs to the Anacardiaceae family. In the Mastichochoria region of southern Chios, this specific variety is cultivated to harvest its natural resin — mastic gum.

Physical characteristics and appearance

• Height: typically 2–3 m, exceptionally up to 5 m.
• Growth habit: low-branching, often resembling a dense shrub.
• Leaves: dark green, oval and pointed.
• Resilience: thrives in rocky, nutrient-poor soil; shallow roots capture morning dew and humidity, allowing it to survive arid conditions.

Despite growing throughout the Mediterranean, the “tears of Chios” are produced only in the south of the island, thanks to a unique combination of soil, climate and centuries of specialised cultivation.

Growth cycle and cultivation

The mastic tree is slow-growing and long-lived, often exceeding 100 years. Key milestones:

• Full development: reached between 40 and 50 years of age.
• Reproduction: mainly by cuttings pushed into the ground in summer.
• Care: needs minimal irrigation once established; aeration and hoeing of the soil stimulate growth.

Mastic production and yield

Resin production follows a clear lifecycle:

• Initial yield: begins after the 5th–6th year.
• Peak production: after about 15 years.
• Decline: minimal after 70 years.
• Average yield: 150–180 g of raw mastic per tree per year (ranging from 10 g to 500 g).

Growers typically favour male trees for resin harvest, and proper spacing between trees is essential for air circulation and maximum yield. You can read more about mastic cultivation and production.
