Before planting, the field should be deeply ploughed, harrowed and levelled. Because the evergreen guava tree is a small to medium-sized plant of about 5-10 m high and has a canopy spread of only 5-8 m, the square planting system (with planting distance of 4m x 4m) is very commonly adopted. Such a planting system allows 625 trees to be planted per hectare.

Guava trees do well with a lot of sunshine, so where possible rows should always run north and south so that each tree receives the maximum sunlight.

To plant, planting holes of 0.3m x 0.3m x 0.3m are first dug. After the hole is dug, 5 kg of organic matter or compost together with 100 g of Triple Super Phosphate (TSP) and 250 g of ground magnesium limestone should be added to the soil before placing the plant in the hole. The plant should be planted with minimal disturbance to the roots and supported with a stake to prevent falling over. The soil should be well pressed to keep the plants firmly in position. Planting of seedlings and clones usually starts at the onset of the rainy season.

Climatic conditions can have a pronounced effect on guava growth. In general, the guava plant likes the sun and is well adapted to the warm and humid tropical areas with annual temperature of about 27- 30°C and annual rainfall of 2000 to 3000 mm. In farms where there is no proper irrigation, it is recommended that planting be carried out in the rainy season.

Guava can be grown in a wide range of soil conditions but will yield better in rich soils high in organic matter. The tree also prefers a well-drained soil but will take temporary water logging. However, it will not tolerate salty soils. Even marginal soils such as tin-tailings, bris and peat can also be cultivated with guava provided proper remedial measures are taken. In general, guava can be grown in areas with pH between 4.5 and 8.2. Although the guava plant grows better on flat land it can also be grown in hilly areas with proper terracing to prevent soil erosion. During land preparation all vegetation must be cleared and ploughed in at least 3 times.
