New Guinea impatiens: when to prune it?
In March cut back an overwintered plant and in June shorten long shoots.
New Guinea impatiens: how to prune it?
- Cut overwintered plants back by about half in March, just above a leaf.
- Pinch or cut back shoots that are too long in June for bushier growth.
- Remove dead, weak or withered stems completely.
How much to cut, and how often?
- There are 2 pruning periods a year: March and June. 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.
