Pittosporum, Plant Profile and Landscaping Uses
Pittosporum species and varieties include both taller growing hedging plants and low growing types. They have become one of most widely used screening plants in both commercial landscaping and home gardens. Wholesale growers offer a wide range of plants suited to different landscaping uses.
It is the variety of leaf colour and size along with different growth habits that make these such a useful plant.
A fast growth rate, and an easy to prune nature are two more aspects that make them so popular.

Pruning Pittosporum
A tough and hardy plant Pittosporum is also easy to prune as a formal hedge. With a few pointers anyone can successfully maintain a neat hedge.
The first factor to take into consideration is that early formative pruning will make life easier later on.
With any size hedge commence by determining the lowest level to be pruned to, this is always at least the lowest part of the hedge or lower unless of course you have a gap.
So looking at the top of the hedge determine a good line. Once you have determined the height you are ready to go.
However it is easier to start pruning the sides as this will allow you to get closer to the hedge when you get to the top.
The sides should be pruned to be a little wider at the ground level than at the top, this allows more light to get to the lower part of the hedge, not essential, but desirable in shaded positions.
You can use shears, loppers or mechanical hedge trimmers. Just remember that leaders of branches thicker than a pencil may need loppers.
Problems
Die back can be a problem after pruning, usually caused by
- Pruning in summer when it is to hot.
- Pruning to hard, anything over 1/3 can cause problems.
- Pruning older hedges hard can cause stress.
- Ladder stability is essential.
