Rolled up leaves on roses are a very clear sign that the roll wasp was active here. After a few weeks, the rose petals will turn yellow and then fall off.
The scroll wasp lays its eggs right on the edge of the rose petals. As soon as the larvae have hatched, they are of course hungry and use the leaf tissue on the underside of the leaf. We already know the episode: Curled Leaves.
Scroll wasp not harmful to the rose
But now comes the good thing: It is in no way harmful to the rose. She just loses a few leaves. You can't do anything about it. However, if you don't like the rolled-up leaves, you simply have to pluck them off.
Removing the leaves is enough
After all, the queen of flowers should also look beautiful. Removing the leaves also has the advantage that the leaf roller wasp can no longer multiply as much, which in turn has a positive effect on the following year. So just remove the leaves - done!
