Description


Cainito is a tropical tree of the family Sapotaceae. It is native to the Isthmus of Panama, where it was domesticated. It has spread to the Greater Antilles and the West Indies and is now grown throughout the tropics, including Southeast Asia. It grows rapidly and can reach a height range of 6 to 18 meters. There are two types found in Sri Lanka discernible by the colour of the fruit. One is purple while the other is green. The Wood is used for general indoor construction and used for fuel.


Planting requirements


Planting season: February to April

Planting conditions:

Propagation While seeds can be used, most successful propagation occurs through cuttings or grafting
Planting method Direct seeding or budding. The seeds germinate easily and are viable for several months. Plant them about an inch deep in a small container kept outdoors. Once the seeds have established roots and are actively growing, you can transplant them into the ground or a larger container. If you chose to start with a sapling, it can be planted straight in the ground. Dig a hole that's 3 times wider and deeper than the root ball
Soil well-drained, loamy soil with pH between 6.0 to 7.5. However, some sources suggest a slightly lower pH range of 5.5 to 6.5
Water Consistent deep watering is emphasized, which is crucial for the tree's health
Light Requires full sunlight

Growing conditions:

Temperatures 25-32Β°C. However, some sources indicate that the tree can tolerate temperatures as low as 22Β°C
Soil Soil must be kept well drained
Water Deep consistent watering
Pruning It is necessary for keeping your plant at an ideal size. Because fruits don't fall off when ripe, maintain it at a height that you're able to harvest. Prune as needed every 1-3 years to keep it in shape. When the tree is mature, maintain a bush canopy, which will boost fruit production
Weed Control Maintain a grass-free area 2 to 5 or more feet away from the trunk of the tree

Harvesting


If grown from seed the Star Apple tree can produce fruit in about 4 years. But if you buy a sapling from a nursery that was grafted onto rootstock or propagated from a branch, it can grow fruit in as few as 1 to 2 years after planting.


Curing


Star Apple does not require a curing stage.


Storage


Star apples are best eaten when fresh but fruits can be stored in the refrigerator for up to two weeks.

Difficulty rating

Low country wet zone

Difficulty:

β˜…β˜…β˜…β˜†β˜†

Explanation: Requires consistent moisture but is prone to root rot in waterlogged conditions. The high humidity can also encourage fungal diseases.
Challenges/Adaptations:

  • Regular monitoring for root rot and fungal diseases is necessary. Ensure good drainage and avoid overhead irrigation.

Low country dry zone

Difficulty:

β˜…β˜…β˜…β˜†β˜†

Explanation: Tolerates drought once established, but fruit production may decrease in prolonged dry periods. The hot temperatures can also stress the tree.
Challenges/Adaptations:

  • Deep watering during fruiting season to maintain productivity. Provide shade during extreme heat.

Mid country

Difficulty:

β˜…β˜…β˜…β˜…β˜†

Explanation: Requires consistent moisture and protection from strong winds. The cooler temperatures at higher elevations may affect fruit production.
Challenges/Adaptations:

  • Provide windbreaks and ensure adequate water supply. Maintain warmer microclimate if possible to encourage fruit production.

Up country

Difficulty:

β˜…β˜…β˜…β˜…β˜…

Explanation: Not well suited to high elevations due to cold temperatures. Frost can damage the tree and flowers, reducing fruit production.
Challenges/Adaptations:

  • Grow in a protected location with a warmer microclimate or use row covers during cold periods. Consider using heat-trapping techniques like mulching or plastic covers.

Companion plants

Companion plants aid growth by attracting beneficial insects, repelling pests, and providing support. They are part of a natural pest control system, maximising space and increasing crop productivity.

Not Applicable

Non-companion plants

Non-companion plants are those that negatively affect each other’s growth when planted together, often due to competition for resources or chemical interference. Avoiding these pairings helps improve plant health and yields.
