moro blood orange - all leaves are yellow
First off I'd like to thank everyone for taking the time to read this post. I am very concerned with my moro blood orange that I bought this June. After I recieved the plant I took off the medium that it came in (might not have been a good idea) and put it in my own soil. After that I noticed that the leaves have been yellowing slowly, but surely. The leaves were also falling off. I do not over water it and watch the soil very closely. It is in a full sun area.
Shock from transplanting?
Not fertilized? (I heard you usually do not do so in the first season anyways)
Are there any other common reasons that I'm missing? If so do you have any tips for me to deduce to finding out which one is the factor? I have done many searches on the internet for this matter and I'm about to give up.
Thanks in advance for your time!
PS I will get some pictures up tomorrow.
