The knowledge of the distribution of the plant root system, mainly of permanent plants, is not well studied in function to several factors, amongst them, the inherent difficulty to collect samples. The present research objectified to know the root system through the excavation method, using water jet, it was removed the soil volume of 10 m³ (5x5x0.4m), subdivided in 0.1 m³ (0.5x0.5x0.4m) showing the root system of the 'Rica' guava. It was verified a vigorous radical system without the characteristics of the main root and with homogeneous distribution, great number of primary root, provided by the adjusted formation of seedling, through herbaceous cuttings.
