Katydids on roses
I
HAVE a problem with katydids eating my roses. Can you please help?
KATYDIDS
are difficult to catch because they are green and they blend in
well. They fly at night and their plant of choice is citrus and
roses — buds, flowers and leaves. Often they don’t cause
significant damage. Katydids are common from March to June.
It is now pruning time for most roses, so by removing the foliage you are removing their food source. They shelter in long grass, so remove any nearby long grass where they can hide. If a chemical control is required, use a systemic insecticide spray such as Orthene.
