How is latex collected from rubber trees?

Latex is collected from the Hevea brasiliensis tree through a process known as tapping. When a tree reaches 5 or 6 years of age, it can be tapped approximately once every two days.1

The standard tapping method involves using a knife to score the tree's bark for half the circumference of the trunk. The cut is slanted downward at a 30° angle, starting from the highest point convenient for the tapper. Each subsequent cut is made directly below the previous one. This process causes a milky liquid—latex—to exude from the wound, which is then collected in a cup.1

Each tapping session typically yields a cupful of latex, containing about 50 grams of solid rubber. To maintain the tree's health and productivity, which can last for more than 20 years, trees are often rested after periods of heavy tapping.1
