Cultivars

Citrus × aurantium
Orange
Citrus × aurantium
Citrus trees can benefit from the shade provided by a larger macadamia tree, and the macadamia tree can potentially benefit from the nutrients released by the citrus tree.
Eucalyptus grandis
Flooded Gum
Eucalyptus grandis

Eucalyptus trees can compete with macadamia trees for water and nutrients, potentially hindering the macadamia tree's growth and nut production.

Inga edulis
Ice-cream-bean
Inga edulis

Inga trees, when planted too close, can compete with Macadamia trees for sunlight, water, and nutrients in the soil.

Scale Insects

Small insects that suck the sap from the leaves and stems. Symptoms include stunted growth, leaf yellowing, and reduced nut production.

Macadamia Nut Borer

A type of moth whose larvae bore into the nuts. Symptoms may include a small hole in the nut, with larvae being present within.

Neem Oil

Effective in controlling pests such as scale insects and other chewing insects.

Compost

Improves soil health and nutrient availability for the macadamia tree.
