Evergreen Shrub Pittosporum

Pittosporum tenuifolium Silver Queen

Pittosporum tenuifolium Silver Queen

The name comes from the Greek for ‘Tar and Seed’, due to the sticky coating of the seeds.

These large shrubs come from the savannah and rain forests of Australia with a few found in southern Africa, southern and eastern Asia and the Pacific Island.
 
Grown for their glossy evergreen foliage which is usually rounded or slightly oval. There are many variegated forms with white, cream and yellow foliage as well as deep purple.  Traditionally used by flower arrangers, these excellent plants look great with palms and ferns adding colour and contrast, but also as specimens in tubs. They trim beautifully into basic shapes.  Purple leaved varieties colour best in full sun, others will grow well in fairly deep shade. Will grow in most soils except very wet. In cold areas shelter from strong winds, in coastal regions they make good hedges and wind breaks.  Trim in spring and mid summer. Sizes range from 1m (3’) to 5m (15’)

Planting Guide

Preparing the soil before planting allows you to make sure conditions are right for your plant. To encourage good  root growth the soil surrounding the planting hole needs to be good enough to entice the roots out from the planting hole. Improve the fertility of the soil by incorporating fertilisers such as Fish, Blood & Bone, Growmore or Vitax Q4. Organic matter can be added, J.Arthur Bower’s Mulch & Mix, New Horizon Multi-Purpose Compost or Farmyard Manure will all add bulky organic matter to the garden. Ideally you should improve a fairly large area around your plant, for larger shrubs this could be up to 2-3m (6.5-10ft) in diameter.

Planting

  1. Dig your hole deep enough to allow the surface of the rootball to be level with the surrounding soil. The hole needs to be about three times wider than the diameter of the rootball.
  2. If the sides of the hole are compacted, break the soil up with a fork.
  3. Rootgrow can be added to the planting hole at this stage. This is a mycorrhizal fungi which helps the root system grow.
  4. Making sure your plant is well watered, remove it from the pot and gently tease the roots out from the rootball.
  5. Place the plant in the centre of the hole.
  6. If you are staking a large shrub, the stake can be placed into position. This needs to be plac ed so the prevailing wind will blow the plant away from the stake. The stake only needs to be about 1/3rd of the height of the plant.
  7. Refill the hole, carefully making sure that soil goes between the roots eliminating any air pockets.
  8. Gently firm, but do not compact, the soil.

Watering

For the first season for smaller plants, and two for larger plants, watering is all important in getting the plant established. Light rain in summer does not penetrate down to the roots, and dry windy conditions will lead to water shortages for the plants. Evergreen plants will need checking through winter as they will be losing water through their foliage. Try to anticipate water loss rather than waiting for the plant to show signs of stress.

Weeding

Keep other plants away from your newly planted shrub. If planting in a lawn keep a 1.2m (4ft6) vegetation free circle around you plant. In the borders keep weeds down by hoeing. Mulching will help in both controlling weeds and grass, but also keeping in the moisture in the soil. Keep the mulch away from the base of woody plants to help prevent rotting of the bark.

Always follow the manufacturers instructions when using fertilisers.
