to grow and care for. Plant this guava right in the garden in warm climates, and in cooler climates, opt for a large container. Let’s look at the ‘Thai White’ variety that produces delicious fruits that are extra high in fiber and immune-boosting vitamin C.
What Is It?
‘Thai White’ guava is a lightly sweet and refreshing fruit. Typically, it’s consumed raw and unripe, sometimes dipped in chili, salt, sugar, or a combination of all three.

It’s a tough small tree that makes an attractive addition to the landscape, though it won’t grow in the ground outside of zones 9-11. Outside this climate, it makes a nice container or patio plant.

Guavas were in cultivation as many as 5,000 years ago in Peru. Spanish and Portuguese explorers imported the species to Florida and Europe. Eventually, they traveled across the continent with their delicious discovery, distributing it to Asia and India.

Legend follows that the fruits of the guava tree were once inedible. A young boy, wanting to feed a hungry beggar, prayed for the gods to make the fruit edible. The gods obliged the boy, impressed with his kindness and compassion, giving the fruit a sweet, tangy, tart flavor we now love.

Characteristics
‘Thai White’ is a mid-sized, evergreen fruit tree that will grow to about 15′-20′ left to its own devices. You can prune it to keep it to a more manageable size, making it easier to harvest the round, green fruits.

The fruit is green with white flesh and has higher sugar, vitamin C, and fiber content than a pink guava. It also tends to have more seeds, lending to its more fibrous texture. The entire fruit, including the peel, is edible.

According to the National Library of Medicine, the fruit, eaten with the peel is, very healthy. It can lower blood glucose levels and triglycerides, making it a great addition to a healthy diet.

The plant is attractive and fits well into a tropical landscape. It usually has one or two central trunks and a many-branched, umbrella-like canopy. The leaves are broad, medium green, and have prominent veining.

Native Area
Guavas are native to Central and South America and the Caribbean. Portuguese travelers brought the white guava to Asia in the 17th century, where it became a popular fruit to grow and eat. The Thai people refer to the fruit as farang, which denotes a foreign person of white race.

Planting
Spring and early summer are the best times to plant your ‘Thai White’ guava. The plant is in an active growth phase at this time and will establish quickly. If you want to grow it in a container, it’s fine to re-pot it any time of year. It will need to come indoors when the temperature drops below freezing.

This tree is invasive in certain areas of North America. In these areas, grow in a container. Loose soil will help this tree to develop strong roots. Dig a hole three times as deep and wide as the root ball to loosen the soil. This may seem like a lot, but it is ideal for root development.
Backfill the hole to the depth of the root ball and position it so that the root ball is level with the surrounding earth. You won’t usually need to amend the soil, so simply backfill, tamp down the soil, and water deeply.

The roots of the guava can be extensive, growing beyond the drop line. For this reason, plant it a fair distance away from your home, structures, or concrete slabs.
