Help with a tangerine tree
I am a lurker of this forums but now I need some help and wonder if you can share your knowledge with me.
I have this tangerine tree (I believe the name is "Daisy") in the ground for about 3 years now and it has not grown a bit, the leaves are yellow with no signs f improvement. I have tried many things and this is (I think) my last try to make it better, otherwise I am sad to say it will have to go to the trash...
I tested the soil about a year ago and the PH was neutral, and I added the nutrients as recommended. I have tried liquid and solid fertilizer (the ones that say "for citrus"), I tried organic matter, mulch... and no mulch but nothing seems to work. Does anyone has any idea why this tree looks so yellow? see pictures:
