Common rue: when to prune it?
In April, as the new shoots start to grow, and lightly in August after flowering.
Common rue: how to prune it?
- In April, cut back by a third to a half, just above young green shoots.
- Never cut into bare, old wood: the plant seldom regrows from it.
- After flowering, cut off the faded flower clusters.
- Wear gloves and long sleeves, and prune preferably on an overcast day or in the evening.
How much to cut, and how often?
- There are 2 pruning periods a year: April and August. You don’t have to prune in every one.
What does it mean for wildlife?
- Don’t cut more than you need to: what stays standing gives insects and birds food and shelter.
Caution: In combination with sunlight the sap can cause blisters and pigment marks on the skin. Always wear gloves and long sleeves. Common rue is poisonous: wear gloves and keep clippings away from children, pets and livestock.
