How to Grow Pittosporum

If your soil is heavy, dig a hole large enough (1 m in all directions) and mix 1/3 coarse sand, 1/3 compost and slow release fertilizer in it. For planting in pot using good quality light potting mix is optimal.
For hedge, grow medium-sized varieties and space them about 1 m apart.
Carefully take out the plant from pot without damaging the roots. Loose soil around its rootball and plant it at the same depth as it was grown previously. Water the plant thoroughly and regularly until it establishes.
