For large infestations
A sustained control effort is required for large infestations. Hand pull seedlings and plants up to 1 m tall. For larger plants, apply a recommended herbicide immediately after cutting. Match treatment areas to the resources available for follow-up works. Under the right conditions, infested areas can be burnt to encourage germination of the seedbank. New seedlings must be removed before they flower.
For small infestations
Destroy established plants before they flower and produce fruit, to prevent the spread of seed. Treat isolated plants with a recommended herbicide applied by spot spraying.
In rainforests
A combination of spot spraying, mechanical removal and biocontrol may be the most effective for rainforest infestations. Keep soil disturbance to a minimum to reduce the risk of stimulating germination. Treat healthy infestations of bitou bush near the edges of the rainforest. Once bitou bush is removed, fast-growing rainforest species will regenerate.
Revegetation in other areas
Once bitou bush is controlled other weeds may invade, so only tackle areas where follow-up control is possible. Follow up with direct seeding or planting of indigenous species.
Follow-up control
Because of the large and persistent seedbanks in the soil, follow-up control is required for about ten years.
Disposal
Remove seeds and burn them. Stands of dead bitou bush can either be left until they decompose or are physically removed. Applying herbicide to stems immediately after cutting should prevent regrowth.
