Two citrus tree issues, one yellowing, one curling.
I bought 7 citrus trees in the last month, all dwarf variety and will all be living in large pots so I can take them inside safely if Phoenix gets any freeze advisory's. I have used large glazed clay pots for all and my soil of choice was miracle grow citrus. They are all getting watered 2x a week right now because its hotter than the surface of the sun right now. They are also in about the same area, I got 5 facing south and 2 facing east which gives them 6-8 hours direct sunlight. I got smith blood orange, moro blood orange, a normal "orange"(didnt tell me what kind), minneola tangelo, bearass lime, meyer limon, and a fukushu kumquat. Needless to say I decided a wanted a mini citrus farm on my patio. They are all doing very well except the moro blood orange and the bearass lime.
The moro blood orange has been slowly turning yellow over the last week. Some of the leaves are now even starting to turn brown. It was doing fine up till the last week or so.
The bearass leaves are also starting to curl a little. Since they are all still green and not yellowing at all so I have been a little less worried about it. It has also had mostly curved leaves since I got it, but it seems to be getting worse.
I have attached pictures of each at two different angles. I am not sure what I am doing wrong, the only thing I could think of with the Moro is its getting over-watered? When I planted each I did 2 inches of medium sized rocks in the bottom so I would hope that is not the problem and they seem to be drying out between watering.
Anyone have any idea what I maybe wrong here? Or are they just settling from being potted.
