Re: Therese Bugnet

Valerie,

Sounds like Cane Borers to me. My sister lost a whole hedge of roses
as she didn't get the infestation down soon enough.

Here's what  Peter Beales book -"Classic Roses"- has to say:

Cane borers are the larvae of wasps and sawflies which lay their eggs
in the ends of freshly cut stems in early summer. Their presence is
indicated by sawdust extruding from holes in the stems. [I've only
noticed the hole at a cut.]  Their presence causes canes to die back,
often to the bud union. Serious infestations can be fatal. To prevent
cane borer damage, seal all cuts in canes larger in diameter than a
pencil with household glue. It is advisable to add a few drop of food
colouring to the glue so that the treated canes may be identified. 

[I'm told you may not see it for years and they can infest all your
roses.] 

So sorry; rose garden nightmare.

Sincerely,
