Can anyone id this Hebe problem?
"Spider" wrote in message ... "Emrys Davies" wrote in message ... "Spider" wrote in message ... Hi everyone, Help! I'm desperate. My favourite Hebe has been afflicted by a disease?/pest?/fungal problem? which has all but decimated it. It appears on all young(er) shoots. There is some distortion, some (mostly) parallel tunnelling, and some whitish powdery deposits. The deposits don't show up too well, but you can see the tunnelling clearly. Early signs of the tunnelling do not show up on photographs, but appear as elongated areas of leaf surface separation, rather like blistering, yet the two surfaces are green and appear healthy. It is very subtle at this stage. However, the new shoot tip looks generally sickly. Some shoots, however, have produced tight green flower spikes, although some of these appear dry and brown (eventually black); some fall off while others remain in the plant. Similarly, some dead (brown) leaves fall while other cling on. The brown parallel tunnelling you see in the pics is, I believe, the same 'blistered' area as above, but it seems older, dryer and sometimes distorted. In one sample I saw (not pictured), was a possible entry/exit hole. However, this break in the tunnel may have been caused by mechanical damage to the brittle leaf. Older and different samples show the tunnels and other areas of damage blackened. http://picasaweb.google.co.uk/Spider...09972487607730 http://picasaweb.google.co.uk/Spider...10684343508322 http://picasaweb.google.co.uk/Spider...10701671843986 This hebe has had a history of black spot, but had previously coped well with it, with a little help. It was vigorous and put on lots of healthy growth and copious flowers each year. This afternoon, as I trimmed it back (to almost nothing :~(( ), I noted several froths of cuckoo spit complete with leaf hopper; a tiny pear-shaped beige casing which may have been a parasitised insect or a pupal case, and several spiders. It was not in this state when it came through the winter. There was some leaf spot and some frosted shoots, but these were pruned out. It had been fed, watered and mulched about six weeks ago. I can't imagine it's something I've done, but I just want to save it if possible. Any ideas anyone? TIA. Spider I feel sure that the Hebe Society http://www.hebesoc.org/ will be able to help you, particularly in view of the fact that you have such good photographs of your problem. Regards, Emrys Davies. Thanks ever so much, Emrys. I'll give that a try. I should have thought of it, but I was panicking and beside myself with misery. Many years ago, I met Graham Hutchins, proprietor of County Park Nursery and a top man in the Hebe Society. With some luck, I may even be able to buy a replacement from him. A couple of months ago, I stuck a handful of cuttings in the ground, but there is no sign yet that they have taken - or, indeed, have escaped the same affliction. My fingers are well and truly crossed! Thanks again. Spider I really hope that you are successful. Let us know how you get on. Regards, Emrys Davies. |
