I just bought a copy of a wonderful book; found it at COSTCO for $10.00.
It's called: "Extreme Gardening...How To Grow Organic in the Hostile
Deserts", by Dave Owens, "The Garden Guy".
You don't have to be an organic gardener to appreciate the book. Great
tips of growing fruit & citrus.
First you might try to identify the variety. The most common are the
Arizona Sweets like Hamlin, Diller, Marrs and Trovita. Marrs is the
earliest and is harvested from about November 1 through mid February. All
of the others are harvested in December and January - dates vary a bit.
There also a number of navel types, the most common is Washington navel.
The navels often will not produce reliably for the first 6 years or so and
many will produce on alternate years. The various Valencia varieties are
the latest and are harvested from mid February through May.
Citrus trees should be deep-watered at the edge of the canopy. Water basins
with a 6 inch berm or depression plus berm work pretty well. I use a 1/2
inch drip line with inline emitters and irrigate over night twice each month
in the summer and once/month in the winter. Many people water more
frequently. Water should be reduced in October so as not to force too much
new growth which can get zapped in cool winters although it has not been a
serious problem for the past 5 years. A tree with a 10 foot canopy
typically needs 250 gallons/month in July and 150 gallon/month in the
winter. Larger trees need more. Citrus needs lots of scarce water and is
not well suited to the desert environment but can produce very well if
enough water is applied. To little water is on of the most common causes
of small fruit. Using lots of mulch slows evaporation.
Mature citrus trees need about 1 - 3 pounds of nitrogen per year divided
equally in three applications. The first is February to support the new
growth in March. The second in May after blossom/fruit drop. The
blossom/fruit drop is a normal thinning process, often called "June drop",
but here it occurs in May. The May fertilizer application also helps get
the trees and fruit through the hot summer. The last fertilizer application
is in September - this has more to do with the sizing of the fruit. It
needs to occur early so as not to force new growth too late in the fall.
Ammonium sulfate is the most common source of nitrogen fertilizer for
cirrus. Phosphorous is sometimes required. There is no need to add
potassium which is abundant in a useable form in our desert soil. The other
macro nutrients and the minor nutrients are sometimes added in commercial
orchards but are seldom needed by backyard citrus trees. I usually inject
Miracle Gro through the drip system. My biggest problems are pocket
gophers in the understory and Bermudagrass along the dripline.

will be surprised to hear they live in a "tropical" zone.

For anyone who grows citrus or wants to begin, this book offers a
complete and up-to-date guide to selecting and growing more than one
hundred varieties of oranges, mandarins, lemons, limes, grapefruit,
and kumquats, as well as exotic citrus. Lance Walheim has tailored his
book to growers in California, Arizona, Texas, the Gulf Coast, and
Florida, and tells also how to grow successfully in cold-winter areas.

http://www.commspeed.net/tfcox/Citrus.htm has directions for
Phoenix care, including a calendar.
Oranges take a full year to develop,and take uniformly excellent
care to develop well, so your chances of having anything tasty
this winter are about zero.
>ps--right now there are oranges, but they are shriveled, small, and

Not enough water, not enough water at the right times (REGULAR
soakings), and a way too hot summer. Start caring for it now and
maybe next year this time you will have a nice fat crop of green
fruit starting to turn color.

Sorry JC, I can't help you with the bermuda grass, but if you wish to rid your
area of pocket gophers, try a trap called "The Black Hole". I've got 3+ acres
and are getting close to keeping them away from my native plant garden with this
trap.

no I'm saying they are not grown only in the tropics as you posted!

it is NOT a "tropical" zone!
Oh now I get it, you read it! More book gardening......BTW Texas isn't the
center of the universe!
Judging by the size of the gators it certainly must be the center for them!

Please, you only continue to spew mindless crap. You haven't a clue as to my
