How to identify thorn apple
Thorn apple grows to a height of around 1m. It has broad and coarsely toothed leaves, white or purple flowers from July to October, and spiny, apple-like fruits. Occasionally the fruits are smooth.
How to get rid of thorn apple
Thorn apple seeds remain viable for many years, so seedlings may appear on newly disturbed ground. However, the plants are easy to remove – simply pull them out or hoe the seedlings. If you pull out the plants before they set seed then simply compost them, but if they have set seed you will need to dispose of them by burning or burying them deeper than 60cm in the soil, to prevent the seeds from germinating. Always wear gloves when handling thorn apple, and wash your hands thoroughly afterwards.
