Site management

Firstly ensure correct identification. Easy to kill with metsulfuron. Follow up 6-monthly; easiest to spot during spring flowering. Don’t replant until seedling regrowth ceases, as privet will grow through groundcover.

Recommended approaches

1. Pull or dig seedlings.
2. Cut & stump paint (1g metsulfuron/1L).
3. All year round drill 1 hole per 20cm stem diameter & fill each hole with 2g metsulfuron (dissolved in approx 50ml water).
4. Spray spring autumn, (5g metsulfuron+10ml penetrant/10L).

Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
