Light requirements
Polyscias albersiana auct. thrives under partial shade to full sun exposure. Direct sunlight may scorch the plant's foliage while insufficient light will stunt its growth.
Temperature requirements
Polyscias albersiana auct. adapts to a broad range of temperature conditions, with the ideal range being between 18°C to 30°C. Temperatures below 10°C may result in leaf drop and stunted growth.
Soil requirements
The plant requires rich, well-draining soil with a slightly acidic to neutral pH (6.0 to 7.0). The soil should retain moisture without becoming waterlogged. A mixture of peat, perlite, and coarse sand is ideal, although other well-draining soil blends can be used.
Cultivation
Polyscias albersiana auct. is a tropical plant native to Southeast Asia that requires bright but indirect light to thrive. It can be grown both outdoors and indoors, but indoor cultivation is more common due to its sensitivity to frost and cold temperatures.
When growing Polyscias albersiana auct. indoors, it is important to provide it with ample space to spread its broad leaves. The plant should be kept in a warm and humid environment with temperatures ranging between 65°F and 75°F and with good air circulation. To promote growth, it should be kept in a well-draining potting mix.
Watering Needs
Proper watering is essential to keep the Polyscias albersiana auct. healthy and happy. This plant requires frequent watering but can be easily damaged by overwatering. Ensure that the soil is moist but not waterlogged, and drain any excess water from the pot's saucer to prevent root rot.
The frequency of watering depends on the temperature and humidity in the environment and the plant's size. Watering should be reduced in winter when the plant's growth slows down, and increased in summer when the plant is actively growing. Generally, it is recommended to water this plant once a week.
Fertilization
Polyscias albersiana auct. requires fertilization during its growing season, which is from early spring to late summer. Fertilization promotes growth and enhances the plant's overall health and appearance.
Choose a slow-release fertilizer that is high in nitrogen, and follow the manufacturer's instructions on the package regarding dosage and application methods. Avoid over-fertilizing, as this can lead to the accumulation of salts in the soil and damage the plant.
Pruning
Pruning is an essential aspect of Polyscias albersiana auct. care and helps maintain the plant's shape and size. Pruning should be done in early spring before growth resumes and should involve removing any dead, damaged, or diseased leaves or stems.
When pruning, use sharp and clean pruning shears to avoid damaging the plant and spreading diseases. Remove up to one-third of the plant's growth to promote branching and a fuller appearance. Avoid pruning during the winter months as this can weaken the plant and slow down its growth.
Propagation of Polyscias albersiana auct.
Polyscias albersiana auct. can be propagated through various methods such as:
Seed propagation
The plant's seeds must be fresh and sown immediately after the seed pods have dried and opened. The seeds should be planted in a well-draining and nutrient-rich soil mix. It is important to keep the soil moist, but not waterlogged, until the seeds germinate.
Cuttings propagation
The stem cuttings of Polyscias albersiana auct. can be taken during the growing season and should be about 6 inches long. The lower leaves should be removed, and the cuttings should be dipped in rooting hormone powder before being planted in a well-draining soil mix.
A plastic bag can be placed over the cuttings to maintain high humidity levels, which can help with the rooting process. After a few weeks, when new growth appears, the bag can be removed.
Air layering propagation
Air layering is another propagation method that can be used. A stem on the plant can be selected and a section of bark and cambium layer be removed from the stem. The exposed area is covered with moist peat moss and wrapped with plastic until roots form.
Once roots have formed, the stem can be cut below the new growth and planted in a well-draining soil mix.
