Roses are early warning system
I DON’T know if you have noticed when you are travelling through grape growing areas that at the end of the row of vines they have a rose bush.
This rose bush acts as an early warning system for the grapes, as roses and grapes attract the same type of diseases such as powdery mildew and the rose has a flower, so it will attract any pest that are around to them first, such as thrips.
There are thousands of varieties of thrips and most of them are about 1-2mm long, so they can be missed.
Thrips love to suck the nutrients from your plants – they congregate on the softer new leaves and flowers as this is where the plant is sending the most nutrients.
The first indications that they are around can be white dots on the leaves and the flowers can have brown broken petals. You often see them in a mass group around the base of a flower.
To help control aphids you can attract lady bugs into the garden, they love to eat them. Also keep the area around the rose free from weeds so they have nowhere to hide.The best way is to spray them with OCP Eco oil or Searles Ecofend.
