Petals falling off dahlias
Can anyone help. My pompom dahlias are losing their petals for no apparent reason. Only one flower at a time is affected and the petals can all be lost in the space of a few hours. They are left in a neat little pile on the ground. The remaing part of the plant seems to be very wet once the petals have been lost.
I have looked in the flower while this is happening and cannot see any bugs. I dont think is is slugs or capsid bugs.
Any help/suggestions - gardener from Ireland?
