We recommend a full sun to part shade position in a wide range of soil types, including light clay or sand. For best results, ‘Kattang Karpet’ prefers a well drained slightly acid soil on a raised bed with a pH of 5.5 to 6.0.
It is tolerant of light frost when young and may sustain some minor leaf damage and purpling of foliage, but will become hardier with age.
We suggest you refrain from transplanting Casuarina glauca once established.
Monitor watering levels in the first season after planting and during the warmer months of the year to maintain adequate soil moisture. Once established and in the cooler months of the year, we suggest avoiding watering to minimise fungal problems.
Fertilise with a general purpose three to four month slow release fertiliser suitable for natives in spring and autumn. Supplementary applications of a complete liquid fertiliser at monthly intervals will assist with plant health and vigour especially in the early stages after planting.
After planting, we recommended you mulch around the plant to a depth of 5 cm to conserve soil moisture and to assist with plant health.
Pruning is not generally required for plant health or vigour but can be conducted for aesthetic reasons.
Pests and diseases
‘Kattang Karpet’ is susceptible to powdery mildew during cool moist weather, especially in shady areas and should be monitored and treated with an appropriate organic fungicide if necessary. Keep an eye out for leaf damage, which can show evidence of leaf chewing caterpillars.
The Casuarina glauca ‘Kattang Karpet’ is available for purchase from the Growing Friends nurseries located within the Royal Botanic Garden Sydney, the Australian Botanic Garden Mount Annan and the Blue Mountains Botanic Garden Mount Tomah.
