Carpodetus serratus prostrata, commonly known as "Marbleleaf," is a native plant to New Zealand. This evergreen shrub is a prostrate, low-growing form of Carpodetus serratus. With its distinctive, dark green, wavy leaves and intriguing marbled appearance, it can add a touch of elegance to any garden landscape. It produces masses of small white flowers in spring, followed by green berries in autumn.
 
Care
Caring for Carpodetus serratus prostrata is relatively straightforward. Here are some essential care guidelines to ensure the plant thrives in your garden:
Location: It prefers partial to full shade - plant it in well-draining soil, and ensure good air circulation to prevent fungal issues.
Watering: The key thing to remember is to keep the soil consistently moist but not waterlogged. Water when the top inch of soil is dry. During hot, dry spells, ensure more frequent watering.
Feeding: Apply a balanced, slow-release fertiliser in spring to promote healthy growth.
Overwintering: In most regions Carpodetus serratus prostrata is hardy. However, in particularly cold climates like Central Otago protect it from harsh frosts by mulching the base of the plant.
Pruning: Prune Marbleleaf to maintain its desired shape and to remove dead or diseased branches. This plant can be trimmed back to encourage bushier growth.
 
Propagation
Carpodetus serratus prostrata can be propagated from semi-hardwood cuttings taken in late summer or early autumn. Root these cuttings in a well-draining medium and provide them with the right conditions to establish roots.
 
Diseases and Pests
Carpodetus serratus prostrata is relatively resilient, but it can be susceptible to fungal diseases, especially if the air circulation is poor. Common fungal issues include powdery mildew and root rot. To prevent these problems, ensure proper spacing and well-draining soil.
In terms of pests, keep an eye out for aphids and scale insects, which can be managed with insecticidal soap or neem oil.
