Several scientific theories attempt to explain why some trees might “cry” red sap:

1. Sap Composition: Some trees naturally produce red or reddish sap due to specific compounds within the sap. For example, the Pterocarpus angolensis, commonly known as the Bloodwood tree, exudes a dark red sap when cut. This sap contains tannins and other compounds that give it a blood-like appearance.
2. Insect Activity: Certain insects, such as scale insects and aphids, feed on tree sap and can introduce microorganisms that alter the sap’s color. These microorganisms, including certain bacteria and fungi, can produce pigments that turn the sap red.
3. Disease and Infection: Trees can become infected with various pathogens, leading to a change in the color of their sap. A notable example is the presence of Fusarium, a genus of fungi known to infect plants. Fusarium infections can cause sap to take on a red hue due to the production of specific pigments as a byproduct of the infection.
