hopefully some of our AZ grower can chime in.

last summer during our drought and 100' temps in TX, my orange trees' leaves curled up. sometime its due to excessive water, sometimes too much heat and sun.

have you fertilized? what brand do you use, how often and at what strength? what's your watering schedule? how much water and how often?

i wouldnt worry about suckers up top, just the ones near the base of the trees.

there's really no correct way to shape a citrus. they can be pruned to look like a single trunk tree, or a wide lateral bush, or a tall vertical bush.

Go to your nearest Home Depot or other big box and buy some Arizona's Best Fertilizer and apply some. It might be considered too late to fertilize but you are in Glendale and your walls should retain some heat in case of colder weather. Also, some iron chelate would be useful. Don't bother pruning, it isn't recommended for citrus unless you have dead or diseased branches. I think you are having leaf issues since the tree is devoting a lot of energy to fruit production. Citrus are very heavy feeders. Arizona's best isn't real expensive (considering you are renting) and is formulated for our soils. Hope this helps and greetings from Tucson! Houstontexas123 asked some good questions. Any other questions, just ask!

I hope Arizona's best includes Manganese; if not, in addition to chelated iron, I would look for manganese. Your leaves show classic manganese deficiency, not uncommon in citrus planted in AZ soils.

Thanks guys!

I posted a detailed response in the late morning, but it disappeared. I think what happened was, I hit the 'preview' button not reading the text in the button and just assuming it was a 'post message' button. Whooops. I will post a better reply (again) later... Just wanted to say thanks for the quick responses. :)

The analysis for Arizona's best is as follows:

13-10-4

Sulfur, 16%
Iron, 5.0%
Zinc, 0.5%
Manganese, 1.0%
