Description: Thai guava is mildly sweet with a crunchy texture. This fruit is usually eaten unripe and raw. A large fruit, often the size of a grapefruit, its white flesh, numerous seeds, and green bumpy peel, are all edible.

A favorite of Southeast Asian food vendors, Thai guava slices are often dipped in a salt/sugar/chili mixture. It’s also julienned and added to green mango or green papaya salads. The peel is rich in phytochemicals.

In Thailand, the fruit is called farang which also denotes Western foreigners. The fruit was introduced by the Portuguese in the 17th century to Asia
Light
Plant guava trees in full sun to ensure they produce an abundance of flowers that will become fruit. These trees need a minimum of six hours of direct sunlight a day but do best when they receive Six to Eight hours of light.

Soil and Water
Guava trees adapt to most types of soil but do best in soil with lots of organic matter and with a pH of 5-7. Make sure the soil has good drainage.

When you first plant a guava tree, water every other day for a week and then once or twice a week through the growing season. In the winter, you can reduce how much you water with cooler temperatures.

Temperature and Humidity
Guavas do best in temperatures ranging from 65-90°F. If you live in an area that has a hot and humid climate but in the winter temperatures drop or there are cold spells, consider growing your guava tree in a large container that you can move indoors for the winter. If you live in a hot climate but without humidity, such as the desert, guavas won't do well

Fertilizer
Fertilize the tree every couple of months. Once a tree is established, fertilizing once every quarter is typically sufficient. During the colder season, there's no need for fertilizer as the tree will be dormant. Guavas need an extra boost of iron and magnesium. Consider a slow-release fertilizer such as 5-5-5 or 6-6-6.

Pruning
Pruning is necessary to keep your guava tree healthy. Use sterilized pruning shears to cut back any diseased branches so it doesn't affect the growth of the tree as well as any damaged branches. If you want to keep your tree to a specific height, prune every other year at the end of winter. Pay attention to any new buds and cut above them as to not snip away new growth.
