what species are particularly prone to cankers?

[JosephD]

don't know alot about cankers but they are caused by bacteria or fungus and form a tumour like growth on a certain area on the tree and there is no cure as far is am aware.

 

what can be done if a tree has a canker? if the canker is on a branch can you just prune the branch off? i know that this is not likely to stop the infection but other than that do you just wait and see what happens and see if the tree fights it off itself?

 

and also what species are prone to cankers just for me to know

[Paul Cleaver]

Red horse chesnut -very common

[Tony Croft aka hamadryad]

cankers- very loose term, many trees, probably all are susceptible.

[Graham]

As said previously many trees are. Populus x candicans aurora and some other hybrids are particularly prone. Malus spp. Fraxinus under stress.

Bleeding canker on horse chestnut is one of the biggies at the moment. Lot of tree surgeons say fell but if you can catch it early it can be treated with decomposition and potassium phosphate. Its associated with sub optimal soil conditions.
