The guava grows equally well on heavy clay, to light sandy, graval bars near streams, or on limestone and tolrates a pH range from 4.5 to 9.4. It is some what salt resistant. Good dranage is recommended however, guavas are seen growing on land with high water table.As already stated guava is successfully grown under tropical and subtropical climatic zones. In areas having distinct winter season, the yield tends to increase and quality improves. It can be grown from sea level to an altitude of about 1515 m. young plants are susceptible to drought and cold conditions. Dry atmosphere at the time of flowering and fruit setting is ideal whereas high temperature at fruit development causes fruit drop.Guava is propagated generally through seed however, cuttings, air layering, grafting and budding is also practiced. Although guava is hard to root, investigations indicate that it can be successfully propagated from cuttings under mist. Leafy shoot-tip cuttings of current season growth (10-12 cm long) treated with Indole butyric acid give more that 80% rooting after six weeks when planted in sand under mist in greenhouse during July-August.
