RE: chlorosis

Hello Nan
 
Thanks for your response.
 
In particular,  the chlorotic Euphorbia was one that I transplanted from another area of the garden where it was not doing well.  It had been in the ground about  5 years and was very sickly (because of too much shade I think) I moved it near to my other E.pulchirrima because that one (probably 20 years old) is doing very well in full sun .  It really 'took' to this new site and put on a huge amount of growth last year but its not looking quite so good now as its somewhat yellow.   I put the iron (liquid) on about 1 month ago and again 2 weeks ago.
 
We have two avocados and they are not fruiting yet ( too young ).One is lovely and green and the other has some typically chlorotic leaves ( yellow with green veins).
 
I'm not quite sure what you mean about 'basic' soil. Ph level is about 6-7 I think.  Do you normally buy  'sulfur' in a garden centre?
 
Best wishes for a Happy New Year with lots of successful gardening!
 
Pamela

A couple of thoughts, Pamela

How close in proximinty are the "chlorotic" plants to the "healthy" plants?  

Is your soil basic? If so, sprinkle some powdered sulfur over the soil at the same time you sprinkle on the iron.  That will lower the pH and help keep the iron available to plant roots.  

How long ago did you add the iron?  Iron doesn't travel down into the soil very quickly so it can take many months to see a difference.

I am pretty sure some of my plants /trees are exhibiting chlorosis. The new leaves are yellow.  Plants affected are  Persea americana, Euphorbia pulcherrima (quite young), Tecomaria capensis,  Acacia baileyana ‘Purpurea’ (new) Strelitzia reginae, (quite young) Some old Hibiscus rosa-sinensis look a bit yellow too.
I have mature versions of all the young affected plants and they do not appear to have the same problems.  I have put chelated iron in the soil around them but there is no improvement.  Has anyone success in dealing with chlorosis? Or what else could it be? We have had quite a lot of rain and the ground is very damp.
