Hi Isitangus. I try not to use the -icides except as a last resort. Prefer to try prevention first and natural remedy second before resorting to chemical warfare but I have been around long enough to know that in intensive nursery situations it is sometimes necessary. I have not explored any of the fungicides as a cure or prevention for the palmatum rot problem yet so I don't know the 'phosphate type fungicides' you mention but it does look interesting - a fertiliser that is also a fungicide???

my manchurian pear hadn't lost its leaves yet so I repotted and pruned pretty heavily- defoliated and despiked-trying to strike all offcuts-----I'm expecting a full recovery and then some----treat em rough ,aint enough

[quote="shibui"]Annatal,
There are a number of species that are semi deciduous - chinese elms, chinese quince are 2 I work with a lot. They do NOT need to have all the leaves off to be root pruned. I have the feeling they are actually dormant in winter, just don't drop the leaves, but I have repotted chinese elm successfully with leaves on including severe root cut back when digging them from the grow beds - no problem. Also remember that we root prune evergreen trees with leaves on no problem. Why such a fuss about a few leaves on when repotting


Hi Neil thanks for chiming in. Evergreens are what they are that is a given ! Chinese elms are are a beast all on their own, i too have bare rooted,chopped and repotted them with leaves. However deciduous such as fruit trees goes against everything i have been taught. I would never do it.I would love to hear from others that practice this and get away with it.

It looks suspiciously like Gumosis to me. Google the symptoms and treat accordingly. I am not saying 100% but i have suffered the same symptoms on my Apple and pear and saved them with a copper sulphate solution. It is easy to check..there will be weeping from the wounds on the bark.
