Orange Tree Help
I just got an orange tree about five months ago and it was healthy. I've been watering the orange tree once every 3 ~ 4 days but then all the leaves started to turn yellow and are gone. Now all I got left is a tree where the branches looks brown and dried up. However, the trunk and also the part where the branch and the trunk meet up of the tree is green.
I'm at a lost as far as what to do. I'm in Yuma and this summer has been very relentless being about 120'f constantly... I really want to keep this tree healthy and would like to know where I should start.
