With proper fertilization, guava can thrive on a wide range of soils and pH levels
Growth requirements
Soil
Guava does best on deep, friable, well-drained, loamy soils; nevertheless, it can thrive on a wide range of soils of pH levels from 4 to 8.2 with proper fertilization. It can tolerate water-logged conditions and a certain degree of salinity.
Climate
Guava thrives well in frost-free subtropical and tropical climates ideally it should be grown in uniform temperatures of 27-28 degrees C all year round.
Guava can also be grown in the savanna and in sub-arid areas (with proper irrigation) and it is extremely drought tolerant.

AN = Ammonium nitrate (33.5% N).
MAP = Mono-ammonium Phosphate (12-61-0).
Multi-K = Potassium nitrate (13-0-46).
Magnisal = Magnesium nitrate ( 11-0-0-16%MgO).
For heavy bearing trees supplemental applications of ammonium sulfate or ammonium nitrate may be desirable during periods of heavy blooming, not exceeding 2 lbs. per year for 10-year old trees.
Nutritional sprays containing zinc and manganese should be used 2 or 3 times a year, depending on soil conditions and production. Copper should be included in the sprays if copper-based fungicides are not used. In calcareous soils, iron chelates specific for these soils may be needed.
