Guava trees propagated from cuttings or grafting give fruit in three to four years. Trees propagated from seed start to fruit in three to eight years.
Guava trees tend to produce 50 to 80 pounds of fruit per year. Florida-grown guava trees produce two crops per year: a smaller crop in the early spring and the main crop in the summer.
To propagate a guava tree from stem cuttings, the cuttings should come from newly matured terminal wood and should be 6 to 8 inches long with up to three leaves. The cutting should be misted and needs a warm soil bed of 75 to 85 degrees Fahrenheit.
