Feijoas, also known as pineapple guavas, are a delightful fruit native to South America and popular in New Zealand. These small, green oval-shaped fruits offer a unique tropical flavor when perfectly ripe. Ripe feijoas give slightly when gently squeezed and emit a sweet, aromatic scent reminiscent of pineapple and guava.
Determining the ripeness of feijoas involves using multiple senses. Visual cues can be helpful, as ripe feijoas often have a slight yellowing of their green skin. However, relying solely on appearance can be misleading. The most reliable method is to pick up the fruit and feel its texture. A ripe feijoa will yield to gentle pressure, similar to a ripe avocado.
Timing also plays a role in feijoa ripeness. These fruits typically reach maturity in late autumn to early winter, generally between April and June in the Southern Hemisphere. In many cases, ripe feijoas naturally fall from the tree, making harvesting a simple task of collecting them from the ground. For the best flavor and texture, it’s ideal to consume feijoas soon after they reach peak ripeness.
Understanding Feijoas
Feijoas, also known as pineapple guavas, are unique fruits with a rich history and impressive nutritional profile. These oval-shaped gems offer a blend of flavors and health benefits that make them increasingly popular worldwide.
Origins and Distribution
Feijoas originate from the highlands of southern Brazil, parts of Colombia, Uruguay, and northern Argentina. They were first discovered by European explorers in the 1800s and named after João da Silva Feijó, a Portuguese botanist.
Today, feijoas are cultivated in various regions globally. New Zealand has become a major producer, along with California and parts of Southern Europe. The fruit thrives in Mediterranean-like climates with cool winters and warm summers.
Feijoas are harvested in autumn, typically from March to May in the Southern Hemisphere and September to November in the Northern Hemisphere.
Botanical Characteristics
Feijoas belong to the Myrtle family, which includes guavas and eucalyptus. The feijoa tree is an evergreen shrub that can grow up to 15 feet tall. Its leaves are dark green and leathery, with silvery undersides.
The fruit itself is oval-shaped, about 1-3 inches long. Its skin is thin and green, sometimes with a reddish blush. Inside, the flesh is creamy white or pale yellow, surrounding a jelly-like center filled with small, edible seeds.
Feijoa flowers are striking, with fleshy white and pink petals that are also edible. These flowers attract birds, which play a crucial role in pollination.
Nutritional Profile
Feijoas pack a powerful nutritional punch. They are an excellent source of vitamin C, providing about 23% of the recommended daily intake in a 100-gram serving. This vitamin C content supports immune function and acts as an antioxidant.
The fruit is also rich in other antioxidants, including flavonoids and polyphenols. These compounds help protect cells from oxidative stress and may reduce the risk of chronic diseases.
Feijoas contain significant amounts of dietary fiber, promoting digestive health and helping to maintain stable blood sugar levels. They’re a good source of potassium, essential for heart health and proper muscle function.
| Nutrient | Amount per 100g |

| Fiber | 6.4g |
| Vitamin C | 32.9mg |
| Potassium | 172mg |
These nutritional attributes contribute to various health benefits, including improved digestion, enhanced immune function, and potential anti-inflammatory effects.
Optimal Growing Conditions for Feijoa Trees
Feijoa trees thrive in specific environmental conditions that promote healthy growth and abundant fruit production. Understanding these key factors is crucial for successful cultivation.
Climate Preferences
Feijoa trees adapt well to various climates but perform best in temperate to subtropical zones. They tolerate temperatures ranging from -10°C to 35°C (14°F to 95°F). These trees prefer areas with cool winters and mild summers.
Coastal regions often provide ideal conditions due to moderate temperatures and humidity. Feijoas can withstand light frosts but require protection from severe cold snaps. In hotter climates, partial shade during intense afternoon sun helps prevent leaf scorch.
Wind protection is important, as strong gusts can damage branches and flowers. Planting feijoas near windbreaks or in sheltered locations promotes healthier growth and fruit set.
Soil and Watering
Feijoa trees flourish in well-draining, fertile soils with a pH between 6.0 and 6.5. Sandy loam or clay loam soils enriched with organic matter provide optimal growing conditions.
Good drainage is essential to prevent root rot. If soil drainage is poor, consider raised beds or mounding. Mulching around the base helps retain moisture and suppress weeds.
Feijoas need regular watering, especially during fruit development. Deep, infrequent watering encourages strong root growth. Aim for consistent soil moisture without waterlogging.
Fertilize feijoas annually with a balanced, slow-release fertilizer. Apply in early spring before new growth begins. Avoid over-fertilizing, as it can lead to excessive leaf growth at the expense of fruit production.
Feijoa Varieties
Several feijoa varieties offer different growth habits and fruit characteristics. Choose cultivars suited to local climate conditions and personal preferences.
- ‘Mammoth’: Large fruits, vigorous growth
- ‘Apollo’: Self-fertile, early-ripening
- ‘Gemini’: Compact tree, ideal for small gardens
- ‘Coolidge’: High-yielding, self-fertile variety
Consider planting multiple varieties to improve cross-pollination and extend the harvest season. Self-fertile cultivars like ‘Apollo’ and ‘Coolidge’ produce fruit without a pollination partner but benefit from cross-pollination for larger yields.
Select varieties based on fruit size, flavor, and ripening time. Some cultivars are better suited for fresh eating, while others excel in culinary applications.
Feijoa Ripeness Indicators
Identifying ripe feijoas involves using multiple sensory cues and understanding their ripening process. Knowing these indicators helps ensure you enjoy feijoas at their peak flavor and texture.
Sensory Cues for Ripeness
Color changes offer the first visual clue of feijoa ripeness. Unripe feijoas have a bright green skin, which gradually fades to a duller green or yellowish-green as they ripen. Texture provides another key indicator. Ripe feijoas yield slightly to gentle pressure, similar to a ripe avocado.
Aroma plays a crucial role in determining ripeness. Ripe feijoas emit a sweet, fragrant scent that becomes more pronounced as they mature. This aroma indicates the fruit’s readiness for consumption.
Taste and texture are the ultimate tests of ripeness. Ripe feijoas have a sweet-tart flavor with a soft, jelly-like interior. Unripe fruits may taste bitter or overly astringent.
Ripening Process and Stages
Feijoas typically ripen from late autumn to early winter, usually between April and June in the Southern Hemisphere. The ripening process continues after picking, but fruits taste best when allowed to ripen fully on the tree.
Early stage: Feijoas are firm and bright green.
Mid-stage: The skin begins to dull, and the fruit softens slightly.
Ripe stage: Feijoas become aromatic and yield to gentle pressure.
Overripe stage: The skin may develop brown spots, and the flesh turns mushy.
Feijoas naturally fall from the tree when fully ripe. Collecting fallen fruits ensures optimal ripeness, but they should be consumed quickly to avoid spoilage.
Harvesting and Storing Feijoas
Proper harvesting and storage techniques are crucial for enjoying feijoas at their peak flavor and quality. Timing the harvest correctly and implementing effective storage methods can extend the shelf life of these unique fruits.
Harvesting Techniques
Ripe feijoas detach easily from the tree or fall to the ground naturally. Gently shake branches to collect ready fruits. Check for slight softness when pressed near the stem – this indicates optimal ripeness. Avoid picking unripe feijoas, as they won’t continue to ripen after harvesting.
Harvest season typically spans late autumn to early winter. Gather fallen fruits daily to prevent bruising and pest damage. Use a soft catching net or place tarps under trees to cushion falling feijoas.
For larger harvests, carefully handpick fruits that come away easily with a gentle twist. Avoid pulling or forcing, as this can damage both the fruit and tree.
Storage Methods
Feijoas have a short shelf life and should be consumed quickly for best flavor. Store ripe feijoas at room temperature for 2-3 days. For longer storage, refrigerate in a plastic bag or container for up to 1 week.
To slow ripening of a large batch, place feijoas in the refrigerator immediately after harvesting. This can extend their shelf life by several days.
For long-term storage, consider freezing:
- Scoop out the flesh
- Puree or mash
- Freeze in airtight containers or ice cube trays
Frozen feijoa pulp can be stored for up to 6 months, retaining much of its flavor for use in recipes.
Avoid dehydrating feijoas in slices, as this results in unappetizing, hard disks. Instead, focus on quick consumption or freezing for preservation.
Enjoying Feijoas in Culinary Creations
Feijoas offer a unique flavor that enhances a variety of dishes and beverages. Their versatility allows for both sweet and savory applications in the kitchen.
Preparing Feijoas for Consumption
