Rolled up leaves of roses are a very clear sign that here Journal tiphiidae was active. After a few weeks, the leaves of the rose turn yellow and then fall off.
The leaf wasp lays its eggs directly on the edge of the rose petals. As soon as the larvae hatch, they are of course hungry and use the leaf tissue on the underside of the leaf. We already know the consequence: rolled up leaves.
Leaf wasp not harmful to the rose
But now comes the good thing: It is in no way harmful to the rose. It just loses a few leaves. There is nothing you can do about it. However, if you don't like the rolled up leaves, you just 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 wasp can no longer reproduce as much, which in turn has a positive effect on the next year. So, just remove the leaves - done!
