Pittosporum 'Wrinkle Blue'

An erect evergreen shrub growing to a height of 4m and width of 2m.

Silver-blue wavy edge leaves on dark stems produce small purple flowers in spring.

Prefers full sun and well-draining soil. It can tolerate most conditions, especially coastal sites.

Always choose healthy well grown plants and plant after autumn rains as the soil is moist and warm and allows plants to become established before winter. This enables them to withstand dry periods during the following summer. Young plants may require thorough watering during dry periods over the first two or three years. Mulching helps to conserve moisture and suppress weeds. Planting success is often improved on clay soils by adding extra topsoil and raising beds. Incorporate coarse sand bark compost or other organic material to improve soil structure.

Before planting ensure the root ball is saturated and remove the planter bag or pot with minimal root disturbance. Trim any broken roots and plant at the same level as in the container. Dig a hole twice the diameter of the root ball and firm in and water once planted. Make sure plants are watered well until established if planting in a drier period. Plant with some general slow release fertiliser and then every spring apply an organic based fertiliser such as blood and bone at a handful per square meter as new growth.

For hedges select small plants as they will establish faster than larger ones and can be pruned to shape from an early stage. Planting a double staggered row of hedging plants will result in a denser screen.

Mulching annually helps suppress weeds and conserve moisture. Organic materials such as sawdust and bark contribute to soil structure as they decompose but keep deep mulching material away from the main stems They benefit from a dressing (50g/m2) of general purpose fertiliser in early spring as new growth begins this will encourage more vigorous healthy growth. Sprinkle evenly and work into the top 2 to 3cm of the soil taking care not to damage surface roots.

The first summer and autumn after planting is critical for young plants; water thoroughly during dry periods. Pests and diseases can have serious debilitating effects on young plants so check regularly.

Prune young hedges in their first year after planting to ensure even dense growth. Hedges planted in autumn should be cut back by half during late spring. Trim again lightly in late summer. During the second winter (or in early spring) trim moderately to remove half the previous seasons new growth. Feed hedges at least once a year with a balanced fertiliser ideally in early spring. Keep your hedge looking good with regular trimming. Fast growing hedges benefit from more frequent trimming.

Fruit is a food source for birds.

Relatively pest and disease-free.
