The soil that is suitable for Rose Apple Farming is deep – loamy soil. The soil should contain a little sand and also limestone so that the plant flourishes well. It requires fertile, well – drained organic rich soil. The pH level, which is preferred for Rose Apple Farming is 6.6 – 7.3.

The climatic regions that are considered good for Rose Apple Farming are tropical – Subtropical regions. They thrive well in warm climatic areas. The planting should be avoided in low lying and heavily shaded areas. The sea level for Rose Apple Farming is 4,400 ft. The maximum temperature, which is required for Rose Apple Farming is 24˚C – 27˚C. The Rose Apple plants can tolerate even frosty weather conditions. The tree grows well in full sun when given enough water.

Land preparation and planting for Rose Apple Farming:

Land which is selected for Rose Apple Farming should be cleaned by removing all the weeds, unwanted and old crop roots, pebbles, stones etc. Then the land should be supplied with manure; the soil should be ploughed to attain fine tilth and smooth texture. After ploughing, levelling and harrowing should be done. Water logging may cause damage to the crop so there should be good drainage in the field.

The spacing of the Java plants while planting them is 6 – 10 cm apart from each other. They should be cared more by fertilizing, irrigating, and eliminating the weeds.

Propagation method for Rose Apple Farming:

Collecting of Seeds:

During the fruiting seasons, the best seeds should be selected for using them as planting material. As, they have short viability they should be taken from the fruit and planted as early as possible. From the most desirable fruits each seed should be selected.

Seed preparation:

There is no need of special preparation of seeds. Seeds should be cleaned and all the flesh from it should be. By doing this we can avoid the fungal attack. No prior seed treatment is required before sowing the seeds.


The seeds should be planted to a depth of 4 cm in the nursery or directly in the main field. The germination period of the seed is 4 – 6 weeks. For fresh seeds the germination rate is high.
