Yellow leaves on plum tree

 


Hi all.

I have a 4 year old vic plum planted last year. some of the older
leaves are
turning yellow. Would I be right in thinking this is due to
lack of nitrogen?
The tree is planted with grass right up to the trunk,
so I thought I would use a
liquid nitrogen feed.

Thanks

Peter

   Yellow leaves could be indicative of a more serious problem.  If the
   leaves turn this color in the fall, this could be a sign that the tree
   is going dormant or dying.  Check the base for entry holes of borers.

   You did not give your location and type of soil, which could give
   more clues to the problem.  Did you get a lot of rain this year,
   and does your soil drain well?

Hmmm ...

Not having any plum trees, so I am not expert.
I lean toward iron deficiency.

The yellowing of leaves is called Chlorosis in normal green plants.

As for using "liquid nitrogen" requires careful use!
In a science class "liquid nitrogen" was used to dip a rose in it and
then smashed on the table. The rose shattered like glass :)
Very Cool Huh :)

This year has produced chlorosis in a number of sun-loving plants and
those that don't like wet feet.

It has been overcast wet and cool (for here) all spring.

So far "summer" has been a little better. At least we're getting some
sun, a bit less rain, some higher daytime temperatures and the long days
are helping a little.

 


Thanks for all the replies, I've been away the last few days. I'm based
in the
UK, Midlands. So we've had some heavy rain recently, but also
allot of sunshine,
for the UK at least. The soils is a little sandy, so
drains quite well. The
yellowing of the leaves is not on this years new
growth at all & mainly on the
older leaves. I've also noticed this
morning that a few plums have dropped also.

My idea of lack of nitrogen was based on a quick search on goggle, as I
didn't
think it was water logged & got plenty of water.

I did mean a liquid fertilizer that also contains nitrogen. I don't
plan to have
my plum tree cryogenically frozen.

Thanks
