My Utah giant has had 1 canker on it since early spring. i got it bare root this winter. It is close to my other cherries and has been the most vigourous of the 4. The crevice grew slowly thru the season and now has stopped. No new ooze and it even has some new wood healing around it.
Is it too late in the season to do something about it?
Has anyone heard of caterizing it with a blow torch for 20 seconds?
Will it come back when it gets wet out again? And is it likely to spread to the others?
Thanx in advance for any help.
