Guavas are a tropical fruit native to Mexico, Central America, and South America. Mature trees of most species are fairly cold-hardy and can survive temperatures slightly colder than 25°F for short periods of time. They are rich in dietary fiber and vitamin C, typically containing four times the amount of vitamin C as an orange.

Psidium 'Tropical Pink' Guava is an evergreen shrub or small tree that is valued not only for fruit production but also for ornamental purposes and fits beautifully into an edible landscape. 'Tropical Pink' puts on a spectacular summer show of fuzzy white flowers set against glossy green foliage. Borne singly or in small clusters, the fragrant flowers appeal to bees and butterflies. The fruits that follow ripen in winter. Attractive and aromatic, they have a greenish yellow rind and juicy, salmon-pink flesh with a sweet, fruity flavor that tastes like a combination of passion fruit, strawberry, and pear.

'Tropical Pink' Guava makes an excellent specimen and will create a great living wall with its dense foliage, which provides a lot of privacy. It can also be trained as an espalier or grown as a container plant. In the garden, 'Tropical Pink' reaches 15 to 20 feet tall at full maturity but can be pruned to maintain almost any desired size and shape. In a container, the tree will be much smaller but will still flower and set full-sized fruits.

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.
