Chilean guava plant care

A Chilean guava plant (Pouteria caimitio) is a fast-growing bush species from the family Sapotaceae native to southern Chile.

The Chilean guava plant is common in many regions of Chile, where it is widely cultivated. In addition to being grown for its fruits, it is also used for its ornamental value. It can tolerate a wide range of soil types and can grow in subalpine, temperate and tropical conditions.

The Chilean guava is a tree in its natural state. Although it is sometimes grown as a small shrub, it can grow to. It is suitable for use in Mediterranean and part desert climates. Although it is drought tolerant, it may be more difficult to grow than other native plants.

Diseases and pests

Chilean guava plants are susceptible to several pests and diseases. In Chile, these pests include the guava aphid (Aphis guavae), which lays its eggs in the leaves and causes leaves to curl and yellow. To counter this, growers use chemical pesticides to control this pest. In some areas of Chile, the causes and effects of this pest are complicated. However, if infected, it is critical to clean up the infected plants quickly. There are two other pests in Chile: the Chilean black scale (Hermetia illucens) and the Chilean hornet (Vespa crabro). Both are known to cause financial losses.

Leaf diseases include various mildews, fungi and viruses. Fungal leaf spot on guavas is caused by species of Phomopsis. In Chile, this disease has been known to be induced by a species of Pseudocercosporella. In addition, bacterial leaf spot on guavas is caused by species of Ralstonia and Erwinia.

Other pests include Chilean ant (Pheidole pallidula), a scale insect that causes severe economic damage, and the Chilean flea beetle (Graphosoma chilensis). Other common species include mites, aphids, leafhoppers, whiteflies, silverfish, aphid-sucking pests such as mealybugs and leafminers, and whitefly-sucking pests such as thrips.

Health issues

Chilean guava fruits are sometimes contaminated by guava anthracnose. Infections of this disease are treated using several methods including the use of copper fungicide. The effects of this disease can include the discoloration of leaves, drops, and flowers, and deformity of fruits and shoots. Guava leaf spot is caused by Botrytis, a fungus that sometimes occurs in association with Botryosphaeria. The fungus then attacks the leaf, causing small brown spots. This disease can be minimized with the use of copper fungicides. The amount of copper needed is high, and the side effects can also be severe.


It is common for guava plants to be classified as either 'early' or 'late'. An 'early' variety is more productive and can be sown as early as February in warm areas, while a 'late' variety grows in cooler climates and can be sown as late as September in temperate areas. Seedlings generally are more resistant to pests. Late varieties are generally more ornamental than early varieties. Early varieties tend to produce larger fruits, but the fruit has a less delicious taste and the plant is not as tall. Late varieties tend to produce smaller fruit, but the fruit has a better taste and the plant can be taller. A variety called 'Selva Nueva' produces a high yield of fruit with dark-red fruit that has a sweet taste and lasts for a long time.
