!Grapefruit plant problems! [PIC]
Well im new to the forums and have got an issue on my hands. I have a grapefruit plant planted on the back side of the back yard of my north facing home in Gilbert, AZ. Purchased from Lowes, I planted it at the end of march of this year.
Since then, it has gotten worse and worse. The leaves started yellowing at first. I tried fertilizing it with a slow-release citrus fertilizer last month and I water it by flooding the basin about twice a week. I dug a hole to check soil moisture levels and it seemed pretty moist. I have even made a barrier around the base to prevent mulch from touching the bark. Any advice/hope is greatly appreciated!!
