yellow leaves kaffir plant

Question

My 1 year old kaffir plant has older dark green leaves and newer yellow green leaves that do not turn dark green. The plant was bought in Holland and has a place at 1 meter from a southeast exposed wall in the southeast of Crete (Greece). It has sun from early morning until early afternoon. The soil is mainly loamy. I made a 60 diameter and 80cm deep hole in which I mixed dry peat and loam 50/50. Temperature until now over 20C by day and around 15C by night, lowest winter temp. isn’t under 5C in the night. As far as I can see, the soil is drained enough. What to do?

Answer 1

It sounds like it is lacking nutrients, either nitrogen or iron. Give the tree some fertilizer that contains both these nutrients.
