Guava Growing Condition
The tree should be planted in well-drained soil where its roots have room to spread. Fertilize growing guavas every one to two months while young and then three to four times per year as the tree matures. Guava trees need a high amount of nitrogen, phosphoric acid and potash, along with some magnesium for maximum fruit production. An example is a formula of 6-6-6-2, worked into soils just prior to the onset of the growing season and then evenly spaced out three times during the growth period.
Water frequently after planting and then keep mature trees moderately moist during the blooming and fruiting seasons. Once established, caring for a guava fruit tree is similar to any fruiting tree care.
