| My Yew hedging (Taxus cuspidata) has been bothered, to a lesser or greater extent, for three years by an as yet unidentified problem. I have had a run-in with Fletcher Scale in the past and pretty much beat it (touch wood) but in any case this doesn't look like any part of the life cycle of that pest in any description I've read. The photo below was taken yesterday (March 29). Past experience suggests that the needles with heavy blistering (if that's how to describe it) will drop at some point in the next couple of months. My Yew hedging (fairly extensive) has frustratingly and inexplicably never been particularly robust despite ample (but not excessive, I have perfect drainage) watering and fertilizing though I'm guessing that this is only related to the problem above in that they might not be able to fight off ailments as well as if they were more vigorous. I have cut into the affected needles and even with considerable magnification not been able to find anything that looks like a creature or eggs. Any thoughts? |
