Sawflies and Yellow Roses
by Becky Corken
Last summer I had an infestation of sawflies.
I would like to know if they overwinter and if so what is the best course of action.
I refuse to use insecticides.
I would also like to know what is the best disease resistant yellow floribunda.
Any info would be greatly appreciaated.
P,S. I live in zone 5
ANSWER: Hi Becky! Sawflies lay eggs, and they are hard to control.
And the larvae could overwinter. So do some real clean up before adding mulch around the roses.
Since you don't like to spray insecticide, I recommend you plant some insect detering plants.
They will help you keep pests away from your roses and other flowering perennials.
Here is my page about the best insect detering plants to plant among your roses.
I like the yellow Julia Childs floribunda rose, and I think you will also.
Plant some blue flowering companion plants with it for a beautiful color combination.
