Pittosporum 'Waihao' hedge spacing

The Pittosporum 'Waihao' hedge spacing is generally 50 cm between the plants. If you want the hedge to fill in faster, you can shorten the spacing to 40 cm. However, going wider than 50 cm will have two effects. The first issue is that the gap between the plants at the base will be harder to fill in, which can cause frustration. The second is that the plants will tend to grow wider rather than upward. At a closer spacing, the plants compete for light, and in doing so, they push each other upwards. Therefore, The Plant Company recommends a 40-50 cm spacing to achieve a fantastic hedge.
