Last fall we did a major pruning of our 5-plant line-up of bougy. They are all growing back in beautifully, but I have noticed 4 to 5 broken limbs each day for the past 2 weeks. I clear them off then the next day there are another 4 or 5 more. I'd say a total of about 30 to 40 limbs have snapped off at the base over the past 2 weeks or so and I'm starting to wonder if its more than just the wind that is snapping them off. They're not quite full enough yet to serve as a hiding place for any small animals so I don't think its that. Is there a beetle or another type if pest that could be doing this? Please advise.
