Arundel Green Pittosporum Pittosporum 'Arundel Green' (f)

Water

Japanese Pittosporum should be watered deeply and thoroughly, allowing the soil to dry out somewhat between waterings. Generally, watering once a week with about 1-2 gallons of water is adequate, but this may need to be adjusted based on the weather and soil moisture levels. Be cautious not to overwater, as this can lead to root rot. During hot, dry spells, additional watering may be necessary to keep the soil consistently moist. Reduce the frequency of watering during the winter when the plant is not actively growing.

Light

Japanese Pittosporum prefers bright, indirect light but can also tolerate partial shade. It's best to place the plant in a location where it will receive morning sunlight and afternoon shade, as intense afternoon sun can scorch the leaves. A north-facing or east-facing position is ideal for protecting the plant from harsh sunlight while providing it with ample light for growth.

Temperature

Japanese Pittosporum thrives in temperatures between 50 and 75 degrees Fahrenheit but can survive in temperatures as low as 30 degrees and as high as 90 degrees Fahrenheit. It's important to protect the plant from extreme cold and frost, which can damage it. Ideal temperature conditions for growth are moderate, avoiding the fluctuation to extremes.

Pruning

Prune the Japanese Pittosporum to maintain its shape and health, removing any dead or damaged branches, as well as to encourage new growth. The best time to prune is late winter or early spring before new growth starts. Pruning can be done annually or as needed to keep the plant neat and tidy and to promote a bushier growth habit.

Soil

Pittosporum, commonly known as 'Arundel Green', prefers a well-draining soil mix, enriched with organic matter such as compost or peat moss. A mix incorporating two parts loam, one part sand or perlite, and one part organic matter works well. The optimal soil pH should be slightly acidic to neutral, ranging from 6.0 to 7.5. Regular testing and adjustment of soil pH may be required to maintain these levels for the healthiest growth.

Repotting

Pittosporum 'Arundel Green', also known as 'Arundel Green' Pittosporum, generally requires repotting every two to three years to ensure adequate space for root growth. Younger plants may grow more rapidly and need repotting annually, whereas older, established plants can be repotted less frequently. Always repot in the spring when the plant is entering a period of active growth.

Humidity & Misting

Pittosporum 'Arundel Green', like other Pittosporum varieties, prefers moderate to slightly high humidity levels. Aim to maintain the humidity around 40-50% for optimal growth. If indoor air is dry, consider using a humidifier or a pebble tray with water to increase the surrounding humidity without directly watering the plant.

Suitable locations

• Indoor

  Place in well-lit room, out of direct sunlight; water moderately.

• Outdoor

  Plant in well-drained soil, sun to partial shade; protect from strong winds.

• Hardiness zone

  8-11 USDA

Life cycle

Pittosporum 'Arundel Green', commonly known as Arundel Green Pittosporum, begins its life as a seed, typically germinating in moist, well-drained soil in a warm environment. After sprouting, the seedling goes through a phase of rapid vegetative growth, developing a foliage of glossy green leaves and a bushy habit. As the plant matures, it forms a woody stem and branches which support the evergreen leaves year-round. Arundel Green Pittosporum will eventually flower, producing small, inconspicuous blooms that are often scented, followed by the development of seed capsules if pollination occurs. The seeds within these capsules mature and, once released, can propagate new plants, continuing the species' life cycle. This plant may live for many years, with a perennial life cycle, providing it is in an environment free from extreme cold as it is not frost-tolerant.

Propogation

• Propogation time

  Spring-Early Summer

• The popular Pittosporum, often known by its common name Japanese Cheesewood, is typically propagated using semi-hardwood cuttings. This method usually takes place during the later part of the summer season. To propagate, choose a healthy, disease-free branch and make a cutting of about 4 to 6 inches (10 to 15 cm) long that includes several leaf nodes. The cutting should be taken just below a leaf node, with the leaves on the lower half removed. You can dip the cut end into root hormone powder to encourage root growth, though this is not always necessary. The cutting is then placed in a well-draining potting mix, ensuring that at least one node is below the surface of the soil. The pot should be kept in a warm, humid environment but out of direct sunlight until the cutting has rooted, which can take several weeks. Regular misting can help maintain the necessary humidity.
