Diseases that impact Geraldton Wax

There are a few diseases that can affect Geraldton Wax. The main risk is fungal dieback.

Dieback is a fungal disease that affects the roots and causes leaves to wilt and branches to die back.

It’s caused by the fungus Phytophthora cinnamomi and is exacerbated by wet conditions.

There aren’t any chemical solutions for dieback, so it’s best to prune away affected parts of the plant. If the entire plant becomes infected, you’ll have to replace it.

Geraldton Wax will benefit from a native fetiliser.

You can fertilize Geraldton wax in late winter and early spring, once all danger of frost has passed.

The amount of fertiliser you should use will depend on what type you choose. Follow the directions on the packet for specific amounts and application methods.

The best soil for Geraldton Wax

A slightly acidic soil helps to keep the leaves from getting rust spots.

Geraldton Wax can be grown in pots or in the ground, but for the best results make sure that your plant is always planted in healthy soil.
