Mountain Plum Pine (Podocarpus lawrencei)

Podocarpus lawrencei, commonly known as the Mountain Plum Pine, is an evergreen conifer native to southeastern Australia. It grows in the Australian high country, from southern Tasmania to the Snowy Mountains of New South Wales.

It thrives in exposed areas at elevations of up to 1,800 m, often creating living carpets over rocks due to wind pruning. The mountain plum-pine is known for its impressive lifespan, with some specimens living up to 600 years. This plant is valued for its attractive foliage, versatile growth habit, and ability to thrive in challenging environments.

Tree Height and Spread

Mountain Plum Pine typically grows as a sprawling shrub or small tree, reaching heights of 1 to 3 metres. However, it can occasionally grow up to 5 metres in sheltered, favourable conditions. This plant is known for its low spreading habit, which makes it an excellent ground cover or low hedge in gardens and landscapes.

The majestic Podocarpus lawrencei can grow and spread from 1 to 4 meters, forming a picturesque and lush green presence in any landscape. Its branches are intricately woven and dense, bestowing the plant with a captivating mounded or layered appearance.

The striking dark green, needle-like leaves are petite and densely clustered, enhancing the plant’s allure. These plants are dioecious, meaning they possess distinct male and female counterparts.

In the spring, the male plants produce elegant pollen strobili. In contrast, the female plants bear vibrant red, fleshy berry-like structures with robust green seeds in late summer, creating a captivating contrast against the deep green foliage.

Preferred Soil Type

Podocarpus lawrencei is highly adaptable and can thrive in various soil types. It prefers well-drained soils, including sandy, loamy, or gravelly substrates. These soil types provide drainage and aeration to support healthy root growth and plant development.

While the Mountain Plum Pine is tolerant of poor and rocky soils, it benefits from soil rich in organic matter. Incorporating compost or other organic amendments into the soil before planting can enhance fertility and improve soil structure. This practice promotes robust root development and vigorous growth.

Preferred pH

Mountain Plum Pine prefers soils with a slightly acidic to neutral pH range of 5.5 to 7.0. Maintaining this pH range ensures optimal nutrient availability and overall plant health. Regular soil testing can help monitor pH levels, and appropriate amendments can be added to adjust pH as needed.

Planting and Care

Planting Site: Choose a sunny to partially shaded location for planting Podocarpus lawrencei. While the plant thrives in full sun, it can tolerate partial shade, especially in hotter climates. The Mountain Plum Pine is well-suited to cool, temperate regions and withstand frosty conditions.

Watering: During the establishment phase, water young plants regularly to encourage deep root growth. Once established, the Mountain Plum Pine is relatively drought-tolerant and requires less frequent watering. However, occasional deep watering helps maintain plant health and vigour during prolonged dry spells.

Mulching: Apply a layer of organic mulch around the base of the plant, extending out to the drip line. Mulch helps retain soil moisture, suppresses weeds, and slowly releases nutrients as it decomposes. Keep the mulch a few centimetres away from the trunk to prevent rot and pest infestations.

Pruning: Prune Podocarpus lawrencei to remove dead, damaged, or diseased branches and to maintain a desired shape and size. Regular pruning helps keep the plant’s structure and encourages healthy growth. Pruning is best done during the plant’s dormant season to minimise stress.

Fertilising: Although Mountain Plum Pine can grow in nutrient-poor soils, applying a balanced, slow-release fertiliser during the growing season can enhance its growth and overall health. Avoid over-fertilising, as it can lead to nutrient imbalances and problems.

Pest and Disease Management: Podocarpus lawrencei is generally resilient to pests and diseases but can be susceptible to scale insects, aphids, and fungal infections. If necessary, inspect the plant for signs of pests or diseases and implement appropriate control measures, such as insecticidal sprays or fungicides.

Benefits and Uses

Mountain Plum Pine is an excellent choice for gardens and landscapes due to its attractive foliage, low maintenance requirements, and versatility. It can be used as a ground cover, low hedge, rock garden, or alpine planting. The plant’s dense growth habit and tolerance for harsh conditions make it suitable for erosion control and stabilising plantings.

Additionally, Podocarpus lawrencei provides habitat and food for wildlife. Its berries attract birds, while its dense foliage offers shelter for small animals. As a native Australian plant, it contributes to biodiversity and supports local ecosystems.

Podocarpus lawrencei, or Mountain Plum Pine, is a resilient and attractive plant that offers numerous benefits to natural and cultivated landscapes.

Its low spreading habit, tolerance for challenging conditions, and ecological contributions make it a valuable addition to gardens and rehabilitation projects. By providing the right soil conditions, regular care, and a suitable planting site, you can successfully grow Mountain Plum Pine and enjoy its many advantages in your landscape.
