Annona reticulata: features

Annona reticulata, also known as sugar apple, custard apple and ox’s heart, is a small, tropical, evergreen deciduous tree native to the West Indies. Initially, it was introduced to the continent, where it is currently cultivated in southern Mexico, Central America, Peru, and Brazil. Green, pinnate, oblong-lanceolate to lanceolate leaves that are long-pointed and oblong-lanceolate in shape are a distinctive feature of this 20–35 foot tall plant (4–8″ tall). Foul smell is produced when the leaves are crushed. Near the northernmost range of its distribution, the leaves may drop during the winter (for example, in southern Florida). In spring, small hanging clusters of fragrant, yellowish-green flowers (up to 1″ long) appear. The flowers are followed by reddish-yellow to brown fruits (up to 5 inches long) with tasty, custard-like white flesh. Typically, each fruit weighs 1-2 pounds. Each fruit has a polygonal plate cover. Because of the potential for reticulated fruit skin, this specific epithet is used. The shape (from heart-shaped to roundish to irregular), the taste and quality of the fruit varies (juicy and sweet to firm and medium).

Annona Reticulata: Key Facts

What is Annona reticulata?

Annona reticulata is a small deciduous, semi-evergreen tree belonging to the Annonaceae plant family. It is part of the Annona genus, a class of flowering plants that includes 166 species of trees and shrubs from the Neotropical and Afrotropical forests. Currently, seven Annona species and one hybrid are cultivated for domestic and commercial use. Annona reticulata is widely used because of their edible and nutritious fruits.

Annona reticulata: natural habitat

The native habitat of the Annona reticulata plant is in the Caribbean and Central America regions. It grows in areas of Central America up to 1,500 m above sea level, with wet and dry seasons. It is cultivated and naturalized in tropical regions such as Southeast Asia, Taiwan, India, Pakistan, Australia and Africa. In India, plant species have been transferred from early cultivation to the wild.

Annona reticulata: propagation

The plant can be cultivated in home gardens. It finds its value as a rootstock for improved Annona species including the sugar apple. This is especially necessary in humid conditions. In addition, the plant is also considered as a genetic resource for hybridization.

Annona reticulata: how to grow?

Fill a container with potting soil that drains well. A seed starting mix, either purchased or homemade, can be used. In a pot, the seeds should be buried about an inch deep with a 2-inch gap between them. To make sure the soil doesn’t dry out and the seeds can germinate, fill the pot with water and set it somewhere with indirect sunlight. Annona reticulata takes three weeks to germinate at 18 to 25 °C, and then when the seedlings reach a height of three to four inches, it is time to transplant them.

Annona reticulata: how to care?

To grow Annona reticulata, all you need is a moist environment and adequate drainage. It does best in moist climates and a variety of soils.

sunlight and heat tolerance

Plants have moderate sun tolerance. However, they will require sufficient sunlight for their proper development.

cold tolerance

Annona reticulata is not tolerant of frost. After it is established, the plant may be able to tolerate less light frost.

Soil

Growing Annona reticulata requires a site that has a relatively low elevation, deep, rich soil; abundance of water; and good drainage. They are able to survive in a variety of soil types, but they do best in well-drained, medium-grade soil that has a pH between 6.5–7.6 and moderate fertility.

Water

When the tree enters its dormant period, you should stop watering it completely and instead give it a thorough soak every two weeks. Midwinter is the time to fertilize cherimoyas with a balanced fertilizer such as 8-8-8, and then do so again every three months. You should keep increasing this amount every year until the tree begins to bear fruit.

climate

Each species of Annona originates from the tropics and thrives in hot, dry climates. When custard apple is blooming, it needs a hot, dry climate, but when it is setting fruit, it needs high humidity. Flowering occurs in May when the weather is hot and dry, while fruit formation occurs when the monsoon season begins. Pollination and fertilization can be affected if the humidity level is too low.

diseases and pests

The most frequent causes of injury are frostbite, which occurs when temperatures are too low, and burns, which occur when temperatures are too high. Leaves fall because there is less water. When growing conditions in the soil are either too dry or too wet, the plant’s roots begin to rot. This annoyance can be prevented by using suitable soil and watering properly.

sorting out

Regular pruning of the plant may be required to promote its growth. It helps in the structure of the plant. In addition, pruning helps increase the number of flowers per branch. It also helps in fruiting. Also, diseases or insect infested parts of the tree can affect healthy branches, pruning helps to remove such branches.

Annona reticulata: harvesting

A well-cared for mature tree can produce fruit weighing up to 100 pounds. When the fruit is fully ripe and no longer green, it is time to pick it. Over time, the skin of the fruit becomes more pliable and yields to light pressure when ripened. The skin is extremely delicate, so the fruit needs special care.

Annona reticulata: Allied pest

Calcid fly causes severe damage to Annona reticulata. In India, ripe fruits are protected from bats by keeping them in bags or nets.

Annona reticulata: poisoning

The kernels of the seeds are extremely poisonous. Along with the seeds, the leaves and unripe fruits also have an insecticidal effect. Lice can be killed by the juice of the leaves. The caustic and burning sap produced when the branches are cut can cause significant damage to one’s eyes. The bark has an annonine concentration of 0.12%. When an extract from the bark was injected into an experimental toad, it resulted in paralysis of one of the toad’s hind limbs.

Annona Reticulata: Health Benefits

Annona reticulata plants are known to have extensive medicinal properties. They have traditional uses in the treatment of epilepsy, dysentery, bacterial infections, fever, cardiac problems, etc. The fruit is known to be an anti-oxidant and helps in promoting digestive health and preventing blood pressure.
