How to Fertilize Pittosporum

Pittosporum can fill a sunny or partly sunny landscape area as a shrub or hedge. Hardy in U.S. Department of Agriculture zones 8 through 10, gardeners may need to protect these shrubs from uncommon winter freezes if they occur. As you cultivate and tend these attractive, evergreen shrubs, fertilize pittosporum carefully to keep it healthy and vibrant. Time the fertilization for pittosporum carefully to avoid damaging the tender foliage from cold temperatures.
