Pittosporum Silver Sheen

This is no ordinary green shrub. Pittosporum 'Silver Sheen' shimmers with silver in sunlight when its shiny, lustrous green leaves sway in the breeze on slender black branches. Also known as Silver Sheen Kohuhu or Tawhiwhi, Pittosporum tenuifolium 'Silver Sheen' is versatile and very useful as a loose and lacy privacy screen, a tightly sheared boxed hedge, or as a specimen shrub with delicate, distinct foliage in its natural form. 'Silver Sheen’ has a growth habit that is more loose and open than regular Pittosporum tenuifolium, and has smaller leaves.

Here’s how to plant and care for the elegant Pittosporum Silver Sheen:

Planting Guide:

Location:

• Choose a spot with full sun to partial shade. It grows best in bright light but can tolerate some shade, especially in hot climates.
• Ensure there is enough space for the plant to grow to its mature size, which can reach 15-20 feet tall and 6-8 feet wide.
• Good air circulation helps maintain plant health, so avoid overcrowding.

Soil:

• Prefers well-drained, fertile soil. It can adapt to a range of soil types, including sandy, loamy, and clay soils, as long as they drain well.
• If planting in heavy clay, consider amending the soil with compost or organic matter to improve drainage.

Planting Steps:

1. Dig a hole twice as wide and as deep as the root ball.
2. Place the plant in the hole, ensuring that the top of the root ball is level with the surrounding soil.
3. Backfill the hole with soil, gently pressing it down to eliminate air pockets.
4. Water thoroughly after planting to help settle the soil around the roots.
5. Apply a 2-3 inch layer of mulch around the base, keeping it a few inches away from the stems to retain moisture and reduce weeds.

Care Guide:

Watering:

• Water regularly during the first year to help the plant establish a strong root system. Keep the soil evenly moist but not soggy.
• Once established, Pittosporum 'Silver Sheen' is relatively drought-tolerant, but it will perform best with regular deep watering, especially during hot, dry periods.
• Avoid overwatering, as this can lead to root rot.

Fertilizing:

• Feed with a balanced, slow-release fertilizer in early spring to promote healthy growth.
• If the plant shows signs of nutrient deficiency (e.g., yellowing leaves), a second light feeding in mid-summer may be beneficial.
• Avoid excessive nitrogen fertilizers, which can cause rapid, leggy growth.

Pruning:

• Prune lightly in early spring or after flowering to maintain shape and control size. Pittosporum 'Silver Sheen' responds well to trimming and can be shaped into a hedge or kept as a neat, upright shrub.
• Remove any dead, damaged, or crossing branches to keep the plant looking its best.
• For a more natural look, limit pruning to just a light shaping and thinning to preserve its airy, open form.

Pest and Disease Management:

• Generally resistant to most pests, but can occasionally be affected by aphids, scale, or mites. Regular inspection and treatment with insecticidal soap or horticultural oils can help manage any pest problems.
• Good air circulation and proper watering practices will help prevent fungal diseases, such as root rot and powdery mildew.

Mulching:

• Apply a 2-3 inch layer of mulch around the base of the plant to help retain moisture, regulate soil temperature, and reduce weed growth.
• Keep the mulch a few inches away from the stems to prevent rot.
