Delta Orange Tree – Sweet Summer Oranges with Exceptional Yield

The Delta Orange is a standout citrus variety that truly deserves more recognition. Originally selected in South Africa, this Valencia type orange has built a reputation for reliability, flavour, and excellent production. If you’re looking for a tree that delivers both quality and quantity, Delta is an outstanding choice.

This is a very heavy and consistent producer, rewarding you year after year with abundant crops of beautiful fruit.

Another major advantage is its long harvest window. The fruit holds exceptionally well on the tree, remaining in great condition for months without spoiling. This means you don’t have to pick everything at once, you can harvest as needed and enjoy a steady supply of fresh oranges over an extended period.

The fruit is seedless with a smooth, attractive rind and is noticeably easier to peel than many traditional Valencia types. Inside, you’ll find juicy flesh with excellent juice content and a well-balanced, refreshing flavour that makes it perfect for fresh eating or squeezing.

The tree itself is vigorous, attractive, and highly productive, making it both a practical and ornamental addition to any garden. If you want to extend your citrus season with a reliable, great tasting orange that performs beautifully, the Delta Orange is a fantastic addition to your collection.

Rootstock options:

Trifoliata (Standard)  - Tree will grow to around 2.5 metres high and 2 metres wide. Best option if you have plenty of space and want a full sized, productive tree.

Flying Dragon (Dwarf)  - Tree will grow to around 1.8 metres high and wide. Best option for growing in a container/pot, small garden, or for those who prefer a compact, uniform citrus tree.

The fruit produced on both rootstock options is the same, as each tree is grafted from the same high-quality mother plant. While rootstocks primarily influence tree size and growth habit, they can also affect natural sugar levels in the fruit.

At our nursery, we select premium rootstocks specifically for strong performance in New Zealand conditions, with excellent pest and disease resistance, cold tolerance, and long-term resilience. Importantly, both our chosen Trifoliata strain and Flying Dragon rootstocks are selected because they support higher natural sugar development, helping produce sweeter fruit compared to many standard rootstocks commonly used elsewhere.



Citrus Care Tips

Watering: Citrus plants should be watered deeply once or twice a week, depending on the soil and weather conditions. Water the plant until the soil is evenly moist, but not waterlogged. Avoid letting the soil dry out completely, as this can cause the leaves to yellow and drop.

Fertilising: Feed citrus plants with a balanced fertiliser (such as a 10-10-10 formula) every month during the growing season (spring and summer). Alternatively, you can use a slow-release fertiliser or a liquid fertiliser. Citrus plants also benefit from the addition of compost or well-rotted manure to the soil.

Pruning: Prune citrus plants to remove dead or damaged branches, and to shape the plant as desired. Pruning also helps to encourage new growth and keep the plant healthy. Use clean, sharp pruning tools to make precise cuts.

Pest control: Keep an eye out for pests such as aphids, mealybugs, and mites, which can damage citrus plants. These pests can be controlled through the use of natural methods such as introducing beneficial insects, or by using pesticides as a last resort

Sunlight: Citrus plants need plenty of sunlight to grow and produce fruit. In most cases, a location with 6-8 hours of direct sunlight per day is ideal. 

 Soil: Citrus plants prefer well-draining, slightly acidic soil with a pH of 6.0-6.5. If your soil is not suitable, you can improve it by adding compost or peat moss to increase the organic matter content.

Pollination: Citrus plants are self-pollinating, which means that they do not need to be pollinated by another plant in order to produce fruit. However, the presence of bees and other pollinators can help to improve the quality and quantity of fruit. To attract pollinators, consider planting flowering plants near your citrus trees.

Temperature: Citrus plants thrive in warm temperatures and can tolerate a wide range of temperatures, as long as they are protected from frost. 

Mulching: Mulch around the base of your citrus plant to help retain moisture and suppress weeds. Use a mulch that is well-draining, such as wood chips or pine needles. Avoid using a mulch that is too thick, as this can prevent water and air from reaching the roots.

Pruning for fruit production: To encourage fruit production, prune your citrus plant to allow for good air circulation and sunlight penetration. Remove any branches that are crossing or rubbing against each other, as well as any branches that are diseased or damaged.
Pesticide use: If you need to use pesticides on your citrus plant, be sure to follow the instructions on the label carefully. Wear protective clothing, such as gloves and a mask, to avoid exposure. Avoid applying pesticides when pollinators are present, and wash your hands thoroughly after handling pesticides.
