Symptoms

- In spring, brown spots develop on leaves often ringed in yellow. These spotted areas later fall out giving a distinctive 'shot hole' appearance. Cankers enlarge rapidly on the stems in spring and stems exude a sticky gum. Leaves on cankered stems are yellow, then rapidly shrivel and die.

Stella cherry

Question from mike lewis

I have a stella cherry purchased as a bare root tree last october kept in a 15" tub until february this year then planted in its growing position following all the attendant advice for planting new trees, ie good soil, blood fish and bone, with added well rotted manure.

I appear to have been infected with bacterial canker (shot holes in leaves which are very droopy and unhealthy looking) I tried systhane fungus fighter and provado ultimate bug killer during the summer with no apparent results.
I read on your site to try bordeaux mixture which I have but feel its a bit early to use it.
The other issue is could this problem have been imported from an old flowering cherry tree which is within 30 feet, this tree was badly attacked by blackfly early season (none on the stella) the flowering cherry is the worst I have seen it for the past five years and is currently dropping leaves (almost autumnol in appearance).
If the above is the case should I spray both trees with the Bordeaux mixture or even consider removal of the old tree (its abot 15 feet high)

Thanks Mike
