Nemaguard rootstock for Jap plum trees? (forum)

amanda starts with ...
Hi - I am researching a problem with my Japanese plum trees. As usual - there is no indication of the rootstock used (bloody annoying that problem!?)
The problem I am having may be directly related to the rootstock....so - I was wondering if anyone knows if the use of Nemaguard rootstock is common in Aust with japanese plums?
(I have Santa Rosa, Satsuma, Gulf Ruby and Sunrise gulf)
Many thanks for any help here - I am tearing my hair out :(

Hey Jimmy, thanks - are u aware of there are any problems with nutrient deficiencies/uptake with either of those?

I think my 4 plums may be having a roostock related problem with (maybe) the trees not getting enough zinc uptake?

When I googled this - I came across a few references regarding this problem occurring with the Nemaguard rootstock.

In the meantime my Nursery lady is seeing if she can find out for me (was 4yrs ago that I got them)

I can't see anything on the plant labels as to where they came from - just a symbol of a seedling inside a circle.

(Add on: it's ok Jimmy - it's the Olea symbol! Have emailed them for advice - thanks again!)

Both rootstocks are good for heavy soils, nemaguard is more for sand as it has the nematode resisitance that sandy soils need, as nematodes love seeds.

Saying that, have a look at the Grahams Factree website for info on rootstocks.

Ta Jimmy - had a google and there were many references to Iron chlorosis and plum tree rootstocks.

This is a really tricky one :(

Maybe I should just get some iron chelates and spray the trees? They are not looking happy and are now aborting all of the newly formed fruit (older fruit still ok at present) - so it's an acute problem.

U right Jimmy - it's on a Marianna 2624 rootstock - so no help there :(

As long as Marianna good for sandy soils too...
