Purple Guava - Black Guava

Full Sun: Place your plant where it receives 6 to 8 hours of direct sunlight daily for optimal growth and heavy fruiting.
Soil Type: Use loose, rich, well-draining loam or sandy soil with a preferred pH level of 5.0 to 7.5.
Watering: Water regularly during the growing season. Allow the topsoil to dry slightly between waterings. Reduce watering during the winter months or temporarily pause watering when the plant is heavily flowering until tiny fruits form. [1, 2, 3, 4]
