Its resilience also makes the plant suitable in coastal positions and drought-prone regions.

Things to Consider When Growing Casuarina Green Wave

Due to its fast growth, it's one of the most preferred native shrubs by gardeners. However, it's possible for the plant to spread aggressively in some regions. The pollen from Casuarina plants may also cause allergic reactions for those who are sensitive.

In cooler months, the Green Wave plant may lose some leaves, meaning it will have less shade during winter. It's also important to remember that while this evergreen shrub thrives even in poor soils, it may struggle when planted in poorly draining soils.

Lastly, since Casuarina Glauca can reach up to two metres in height and width, this plant may not be ideal for gardens with small spaces or urban landscapes, which are often restricted by lack of space.

Treating Casuarina Green Wave for Pests and Diseases

Casuarina Glauca or Casuarina Green Wave may occasionally suffer from scale insects or fungal diseases if the growing conditions aren't great.

Luckily, you can easily treat infestations using insecticidal soap or neem oil. A horticultural oil spray can also help deal with scale insects.

If fungal diseases are causing your plant trouble, ensure excellent soil drainage and avoid overwatering. Fungal issues can also cause leaf spots. You can remedy this problem by getting rid of infected leaves. You can opt to apply fungicides if deemed necessary.
