To care for Pittosporum tenuifolium ‘Silver Queen’, it is important to provide the right growing conditions and regular maintenance. Let’s dive into the specifics:
1. Soil and Sun: Pittosporum ‘Silver Queen’ thrives in moist but well-drained soil. It is adaptable to different soil types but prefers slightly acidic to neutral soil. Ensure the planting area has good drainage to avoid waterlogged conditions. This shrub can tolerate full sun to partial shade, so choose a location that provides a balance of sunlight throughout the day.
2. Planting: When planting ‘Silver Queen’, dig a hole that is slightly larger than the root ball and backfill with a mix of soil and organic matter, such as compost. This will help improve soil fertility and drainage. Gently firm the soil around the plant and water thoroughly after planting.
3. Watering: While this shrub is relatively drought-tolerant once established, it is important to keep the soil consistently moist during its initial growth period. Water deeply but infrequently, allowing the top few inches of soil to dry out between waterings. Mulching around the base of the plant can help retain soil moisture and reduce weed growth.
4. Pruning: Pittosporum ‘Silver Queen’ generally requires minimal pruning. It has a naturally compact and rounded shape, but occasional pruning can be done to maintain its form and remove any dead, damaged, or overgrown branches. Late winter or early spring is the ideal time for pruning, as it allows the plant to recover before the growing season begins.
5. Propagation: If you wish to propagate ‘Silver Queen’, softwood cuttings are the most common method. Take 4-6 inch stem cuttings from the current season’s growth in summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining rooting medium and keep them in a warm and humid environment until they root. Once rooted, transfer the new plants to individual pots and gradually acclimate them to outdoor conditions before planting in their permanent location.
6. Fertilizing: Pittosporum ‘Silver Queen’ benefits from an annual application of well-rotted manure or garden compost in early spring. This will provide a slow-release source of nutrients and improve soil structure. Avoid using high-nitrogen fertilizers, as they can promote excessive leaf growth at the expense of flower and fruit development.
7. Mulching: Apply a 2-3 inch layer of organic mulch, such as wood chips or shredded bark, around the base of the plant each year. Mulching helps conserve moisture, suppress weed growth, and regulate soil temperature. Be sure to keep the mulch a few inches away from the trunk to prevent moisture-related issues.
Caring for Pittosporum tenuifolium ‘Silver Queen’ involves providing well-drained soil, adequate moisture, and the right balance of sunlight. Regular pruning and annual fertilization can help maintain its attractive shape and overall health. By following these care guidelines, you can enjoy the beauty of this versatile shrub in your garden.
