Jason Casimiroa / White Sapote (Casimiroa edulis)

Developed locally in Northland, Jason variety (white flesh) produces very tasty, medium size, lemony flavoured, smooth fruit. Delicious, without being too sweet.

Wonderful fruit the size of an apple with a thin green skin. The pulp is delicious, creamy and smooth, the flavour is sweet and rich. Generally fruit is mature if it comes easily from the tree with a gentle twist, changes to a lighter colour and is slightly soft to touch. Handle gently as they bruise easily. Store in a cool spot and eat within a few days of ripening. A prolific producer.

This variety is only available in a small number and not available in any big nursery or plant shops.

Plant Care

  • Soil: Cassimiroa thrives in well-drained, fertile soils that are rich in organic matter. It can adapt to a range of soil types, from sandy to loamy, and prefers a pH between 6.0 and 7.5.
  • Watering: This tree requires regular watering to establish a deep and extensive root system, especially during its formative years and in dry conditions. Mature trees are moderately drought-tolerant but perform best with consistent moisture.
  • Temperature: Cassimiroa is suited to mild to warm climates and is somewhat frost-tolerant. It can survive temperatures down to about -4°C once fully established, but young trees should be protected from frost. Optimal growing temperatures range from 15°C to 25°C.
  • Light: Prefers full sun but can tolerate light shade. Sun exposure is crucial for healthy growth and fruit production, so ensure it receives ample sunlight throughout the day.
  • Fertilising: Feed with a balanced NPK fertilizer in spring and again in mid-summer to support growth and fruit development. An additional application of potassium-rich fertilizer can enhance fruit quality.
  • Pruning: Prune in late winter or early spring to remove dead or damaged branches and to shape the tree. Pruning helps promote good air circulation, reduces the risk of disease, and can enhance fruit size and quality.
  • Mulching: Apply a layer of organic mulch around the base of the tree to help retain soil moisture, suppress weeds, and provide nutrients as it decomposes. Keep the mulch away from the trunk to prevent moisture-related diseases.
  • Pest Control: Cassimiroa trees are relatively pest-resistant but monitor for common pests such as aphids, mealybugs, and scales. Treat with appropriate organic or chemical controls if necessary.
  • Flowering and Fruiting: Produces small, greenish-white flowers that are followed by round, yellow-green fruits that turn creamy yellow when ripe. The fruits have a sweet, custard-like flavor and are usually ready for harvest in late fall or early winter.
  • Potting: Can be grown in a large container for the first few years but eventually will need to be planted in the ground to accommodate its size and root system.
  • Feeding Regime: Regular applications of a balanced fertilizer during the growing season support robust growth. Supplementing with organic compost can improve soil structure and fertility, enhancing overall tree health and fruit production.

We ship our plants and garden supplies throughout New Zealand. Due to the increased costs of shipping and packaging, we now apply a minimal delivery charge. After offering free shipping for three consecutive years, we find it necessary to adjust this policy to align with current market conditions. However, we have lowered our prices to help offset this change.

Please note, we do not ship plants or garden supplies internationally from New Zealand. We do export plants and tissue culture materials from our overseas nursery, which requires a minimum order. Please contact us at to discuss your specific requirements.

Additional Delivery Information

  • We dispatch our plants year-round, as most are shipped with soil. During the winter months, we closely monitor weather conditions and may temporarily delay shipments if the weather is particularly severe. Our packing process includes adding insulation when necessary to protect the plants against temperature extremes.
  • In summer, we ensure that plants are thoroughly watered before they leave our nursery. Occasionally, we may need to ship plants bare-rooted, particularly when they cannot be comfortably re-potted into smaller packaging for shipping. We will always discuss this with you in advance if your plant needs to be shipped in this manner.
  • It's important to note that shipping can be a stressful experience for plants, often due to spending several days in a dark, confined space. While most plants withstand this with little to no stress, some may experience leaf drop. However, they generally recover quickly with some additional care, including proper watering and gradual reintroduction to light after arrival.
