Syzygium Paniculatum is a well-known garden shrub with a multitude of uses. It is evergreen, has dense foliage, and grows rapidly to a height of up to 4 m if left unchecked. Syzygium is most often used for hedges, and sometimes as a screen to hide unsightly areas. It has a shallow root system that doesn’t usually damage structures. Syzygiums are sensitive to extreme cold and frost, but will grow almost anywhere.
Start when the plants are young and regularly give the growth points a light trimming. Continue to cut back the sides until the hedge has reached the height you had in mind. When this happens, you can trim across the top to stop any vertical growth and to encourage lateral growth. Thereafter, trim the hedge regularly to retain its neat shape.
As the hedge grows, you need to shape it in such a way that the top is narrower than the base. This allows the entire hedge to be exposed to the sun, which prevents bare patches developing at the base.
