While blueberry ash trees can be grown in a wide range of climates, they will perform best in cool to temperate regions with moist, well-drained soils. They are not tolerant of prolonged drought or frost and should be protected from strong winds.

Caring for the Blueberry Ash tree

Blueberry Ash (Elaeocarpus reticulatus) is a thorny Australian native tree perfect for low-maintenance gardens. Blueberry Ash tolerates many conditions, from full sun to partial shade and damp to dry soils. This makes it an ideal tree for growing in urban areas where space is limited.

Fertilizing Blueberry Ash

Blueberry ash trees are heavy feeders and will require regular fertilizing to thrive. A good rule of thumb is to apply a slow-release native fertilizer twice a year – in early spring and in late summer. If you live in an area with high rainfall, you may need to fertilize more often.


Blueberry ash trees (Elaeocarpus reticulatus) must be watered regularly for the first few years after planting. Water deeply and less frequently, rather than shallowly and more often. This encourages deep roots, which are better able to withstand drought conditions.

Once established, blueberry ash trees are relatively drought-tolerant, although they will produce more flowers and fruit if given extra water during dry periods.

Pruning Blueberry Ash

Blueberry ash can be pruned at any time of year, but it’s best to do it in late winter or early spring before new growth begins. Blueberry ash responds well to both hard and light pruning. Remove any dead or damaged branches as they occur for a more natural look. To shape your blueberry ash, prune it regularly to encourage new growth.

  • When pruning, make sure to cut just above a bud or node. This will help promote new growth in that area. Blueberry ash can also be coppiced, a form of pruning where all the branches are cut back to the same point. This is often done to encourage new growth and can be done every few years.

Common Blueberry Pests and DiseasesPowdery mildew on Blueberry ash tree


  • Aphids are small, winged insects that feed on the sap of trees. They can cause the leaves to curl and distort. Aphids can also transmit viruses.
  • Spider mites are another insect pest that can damage trees. Spider mites are tiny spider-like creatures that suck the sap from the leaves. This can cause the leaves to turn yellow and eventually fall off.
  • Fungal diseases such as powdery mildew and leaf spot can also affect trees. Powdery mildew is a white or greyish-white fungus that covers the leaves. Leaf spot is a brown or black fungus that affects the leaves. Both of these diseases can cause the leaves to turn yellow and fall off.
