Sea spurge: how to prune it?

  1. In March, cut old, withered or toppled stems off at the base; new shoots come from the woody base.
  2. Leave healthy, evergreen stems standing: they will flower later in the year.
  3. Cut off spent umbels if you do not want seedlings.
  4. Rinse your secateurs afterwards: the sap is sticky and irritating.

How much to cut, and how often?

  • One pruning period a year: March.

What does it mean for wildlife?

  • If you only cut back in March, the old stems stand through the winter: insects overwinter in them and birds eat the seeds.
  • As a native plant, it feeds more insects than a non-native species.

Caution: The sap can spurt: wear gloves and protect your eyes.
