Ash disease in garden trees
Ash dieback has hit the headlines lately as the government tries to stop this disease from devastating ash trees in Britain. So far most of the speak has been about woodlands but what should really you do if you have an ash tree in your garden? What signs should really you enjoy out for and what should really you do if you suspect a tree in your garden to be infected?
The disease is brought about by the fungus Chalara fraxinea which is unfold by wind borne spores. The to start with signs you might see are places on the leaves or you might discover that the tree is losing its leaves just before autumn arrives. At first modest twigs will die as the disease spreads in from the leaves. Afterwards, as the disease enters more substantial branches, a canker (discoloured, roughened bark) will unfold upwards and downwards from wherever the infected twig joins the department. This is often a rough diamond form. As the fungus kills the tissue far more limbs will die back until finally finally the total crown is lifeless.
The disease has killed 90 per cent of ash trees in Denmark and is prevalent through Europe now. Most of the conditions recorded in Britain to date are connected to imported nursery stock. As so a lot of vegetation purchased at garden centres and nurseries are now imported from Europe, it is rather possible that your garden ash tree might be infected if it has been planted reasonably lately. Until your garden is a significant place garden with ash trees grown about as portion of wind crack, it is likely that you won’t have typical ash (Fraxinus excelsior ) planted in your garden. Claret ash or Fraxinus angustifolia ‘Raywood’ is a relative of typical ash. With its smaller sized stature, far more sensitive leaves and attractive claret color in autumn, it helps make a great specimen tree. Although Claret ash has been recognised to host the disease, none have still exhibited the typical dieback. Having said that this can not be dominated out in the foreseeable future and you should really nevertheless preserve an eye on this tree. Mountain ash or Sorbus aucuparia is truly a different species and does not go through from this disease.
