Q.Yellowing Leaves On Prunus Laurocerasus
Hi, I propagated these plants from cuttings and planted 7-9 months old plants. After some time they started showing yellowing leaves. I added chelated iron to the soil with no results. The ph was 7.5 so I tried to acidify the soil with acid peat moss and gave iron again. No results again but with months many plants started recovering although they aren t completely fine. The leaves become yellow gradually and some spots on the leaves diseccate and make holes in them. What should I do? In my place, northern Italy, this Kind of plant takes generally four to five years to gather strength and grow above One meter and a half. Is there a way to speed up this process? Thank you very much!

This does appear to be iron chlorosis! I would suspect that the pH has a lot to do with it, as well.
Make sure to test and make sure that the soil does not lack anything else, while you are at it. These article will help:
