Hello I just joined this forum to find help. Idk what I\'m doing wrong my mandarin trees are suffering and I\'m not sure what to do. If you see the pictures the leaves are curling up on one plant and the other is browning and yellow. I have looked up everything everywhere and I\'ve tried everything. I live in Phoenix so it is hot here so I took them out of direct sunlight and move them in a shaded area when it\'s the hottest part of the day. They still get full sun. Watering is every 3 days due to the heat the soil completely dries. I was told fruit likes moist soil so I have been keeping it damp. I have given it citrus nutritional spray from souther ag. And nothing they are staying the same I was told leaves cup like that due to to much water and I stopped my watering for like 3 days and the trees wilted really bad so now I do every three days and they don\'t wilt anymore. I was even told to keep them out of direct sunlight here in Arizona because it\'s to much for them. Any information would be great. I grew up with a mandarin tree and I would love to get fruit one day and have another big tree or two
