When & How to Trim Citrus Trees in Arizona

 was taught the Five C’s of Arizona when attending Elementary school in Tempe, AZ. These were: Cattle, Copper, Citrus, Climate, and Cotton. This article focuses on the fourth factor in the list, climate. While the climate in Arizona is great for citrus tree growing, not everyone understands how to properly care for these trees. One of the largest and most common mistakes made, is knowing when and how to prune a citrus tree. While many stress over ‘when’ to prune a citrus tree, this is not the most significant question. There are some citrus trees that may never need trimmed. The real question may be ‘why should citrus trees not be trimmed?”

Why Citrus Trees Should NOT Be Trimmed

A garden expert with The Arizona Republic was asked by a Valley resident at what time her citrus trees should be trimmed, part of the response included “Homeowners often trim for appearance, but do not realize citrus trees are actually a bush with naturally low growing branches. This is the natural method for protecting bark and fruit…”.

People that drive by the old groves in East Mesa may see old citrus trees and consider them to be overgrown shrubs. It is a common misconception that trimming citrus trees is the same as another tree type, and can cause a shorter citrus tree lifespan in Phoenix.

For this reason, I prefer readers to begin asking ‘why’. What is the reason for trimming the citrus tree? This should be asked prior to ‘when’ citrus trees should be pruned. The overall health of the citrus tree should be considered whether the goal is fruit production optimizing, or just making it appealing to the landscape.

How to Trim a Citrus Tree

When trimming/pruning citrus trees, even at the optimal periods, it should be minimal. It was stated by ‘The Garden Guy’, Dave Owens that “Citrus trees prefer to grow naturally without trimming. The more deadwood and foliage, the better protection from the sun.”

Also, John Begeman, also an Arizona garden expert indicated “The more leaves a citrus tree has, the more fruit and better taste. ” In addition, he recommended only pruning “If you must, and only with correct technique”.

A 1987 article from Lowell F. True outlined that while some trimming could be required, but the best approach is to leave low hanging branches, referred to as a ‘skirt’. If trimmed, it should only be enough to provide easier fertilizing and watering. Trimming of errant branches can be done, especially when rubbing against other branches. Meanwhile, the tree’s silhouette created by outer foliage can be ‘shaped’ for appearances, but proper techniques and care should be taken to avoid allowing too much bark to be exposed to sunlight.

There is a single pruning technique that should be used, no matter the time of year, even more important if citrus trees are maintained for fruit. This technique is known as removal of sucker growth. Also referred to as ‘water sprouts’, these suckers sprout out the tree trunk and sometimes the roots. While a layman might find it necessary from desire or intuition towards making the citrus tree more appealing, there are good reasons behind this. It was said by True to “Ensure all suckers are eliminated when developing under the bud union (site of grafting). These are rootstock variety which do not bear an edible fruit. If allowed to develop, suckers take control it will cause your edible fruit to revert into an undesired variety.”

A significant ‘when’ associated with pruning includes limbs which were killed by frost. These should not be removed until after the spring growth has begun, this way you’re sure how bad damage is.

When to Trim Citrus Trees in Arizona

Spring is the optimal time for trimming citrus trees. If they are trimmed between the middle of March to early May, it reduces the risk of the tree being damaged by extreme temperatures. The citrus fruit is ripened during late fall, with most varieties coming in between November to February. It is acceptable to do minimal pruning through this period.

During summer there is risk of heat damage, while winter can cause danger from frost. Citrus trees a very sensitive when it comes to sun damage, especially in the hottest months and days in Arizona heat. If your citrus tree is not properly shaded through the afternoon, any bare branches or trunks will need wrapping or painted (aka. Whitewashed) to add protection from the sun. The areas exposed to direct sunlight in the afternoon are the most vulnerable, these will be on the Southwestern sides. This is the reason over pruning your citrus trees should be avoided. Any branches in direct sun will be burnt, while direct sunlight exposure to the trunk can fully kill the tree.

These are the reasons I emphasize the importance of knowing how and why to trim citrus trees, instead of when you should trim citrus trees. The key factor for when to trim, is the sunlight. The key factor for how to trim a citrus tree is keep it minimal. After all, they are all simply large bushes.

The How and When of Pruning your Fruit Trees


The best time to prune fruit trees in Arizona is when it’s cold and the trees are dormant. In Arizona this is typically from February through about April. Any time there will be extensive pruning it should be done earlier than later to avoid leaving large sections of your tree’s bark exposed to direct sunlight. Phoenix Trim-A-Tree offers tree pruning all over the Phoenix valley and can help you make beautiful, healthy, and fruit producing trees. Pruning fruit trees needs to happen when the leaves are off and the tree is dormant. It will be easier to see what you are doing and removing the dormant buds or growing points will invigorate the left over buds. Summer pruning that is normally done by food manufacturers will remove the leaves which slows down fruit ripening and will expose the fruit to sunburn. Summer pruning can be used to slow down vigorously growing trees or those trees that have gotten too large. It is best done in the early summer.


Fruit trees require a different approach for what stage of life they are in, what goal you have for your tree, and what if anything is wrong with your fruit trees. See below for specific information for trees both young and old, and trees with dead or dying limbs.


Right after planting a new tree, you should cut it off to a short stick that is around 25 to 30 inches tall and cut off side shoots that have less than 1 or 2 buds. This will encourage low branching and will equalize the root and top system. Paint your tree with a white latex paint to protect it against sunburn and borer attacks. Low vigor, your young tress need to be pruned heavily and encouraged to rapidly grow for the first 3 years without a lot of fruit. Leave most of the small branches untouched for late fruiting. Young trees may be pruned less or not at all and are encouraged to fruit earlier with branch bending.


Topping the vertical branch encourages the growth needed to develop the tree and will create a bushing effect. Topping the horizontal branch is to renew the fruiting wood and to thin the excess fruit. Thinning vertical branches will open the tree to more light while thinning the horizontal branches will remove the fruit. Horizontal branches that are left uncut will have earlier fruit and heavier crops. Upright branches will normally remain vigorous and vegetative. Horizontal branches will have more fruit. Having a good combination for the two is needed for fruiting. Branches that have been bent 45 to 60 degrees will achieve this balance.

Removing the broken or diseased branches. You should remove the water sprouts, competing branches, and suckers that are growing straight up into the tree. The downward bending branches that are bent more than 90 degrees will eventually lose their vigor and will only produce small fruit, you should cut the part that is hanging down. New growth will happen where you make the cut. The influence of the cut will only affect the bud within 1 to 8 inches of the cut surface and not 4 feet down the tree. The more buds that are cut off the more vigorous the new shoots will be. Sun exposed wood will remain fruitful and will produce the largest fruit. Shaded branches will stop fruiting eventually and will never produce again without topping and renewing the whole tree. Prune most the top of the tree so that lower branches will be exposed to sunlight. You will need to make clean cuts within a fourth of an inch of the bud so that it doesn’t leave stubs.


The best time to have your citrus tress pruned in Arizona is February through April. This is when the trees are most dormant and before they have bloomed. Although flowers may exist in a very small unseen state removing some through pruning should not impact your yield in all but a minor way. It’s important to take care of extensive pruning as early as possible to give your tree time to come out with new leaves. Shade on the trunk, limbs, and branches is a necessary element of your tree in the heat of Arizona.


Grape, kiwi, peach, and nectarine will bear on the last years shoot growth and they grow a lot so you need to remove at least 50% of the prior year’s growth. For apricots, plumcots, plums, pears, apples, persimmons, feijoa, cherry, almond, pecan, chestnut, walnut, olive, and figs which will bear on less vigorous shoots or spurs, you should remove about 20% of the prior year’s growth. For any citrus fruits, just keep the skirts pruned up off of the ground.

When I first heard the phrase "Indian Reservation", it seemed to me that behind it was the riddle of the wisest, some secret rites of initiation into hunters and warriors, an original language, clearly defined profiles and prominent cheekbones of Elusive Arrows and Proud Antelopes, well, and other “other”, which I only knew about from The Last of the Mohicans. The map of Western America is full of reservations. There are dozens of them in states from Washington to New Mexico. Books report that "outsiders" are not allowed on certain reservations. That you can’t even peep at their ceremonies, and if you want to take a picture, forget it! Even if you want to capture on film some red-skinned descendant of the Swift Deer, you are supposed to ask his permission. In short, everything reinforced the mystery of the mysterious tribes that ripped off their scalps and easily rode horses without saddles.

Alaska also has an abundance of Indian reservations. There, perhaps, was my first acquaintance with them. In Juneau, in fact, the capital of the largest state in America. They were dozens of drunken faces, red both from the genetic color of the skin and from the heavily drunk alcohol. It was a Saturday. They wandered the streets with a detached face, hung out at the shops with booze, lay around the bars, lazily chewed one dollar hamburgers bought in fast food, which are very few in Alaska, in general, they spent their day off culturally. There were as many drunk women as there were drunk men. The younger ones were often not drunk, but their fat bellies and asses bulged out of their worn trousers, and on their round faces, shiny with overeaten fats and sugars, you could bake XXL pancakes. The city in which I lived was never inhabited by natives because of the eternal winds and steep mountains. But there were quite a lot of them in Whitehorse, the capital of the Yukon, where I went for groceries, and just stroll through the Canadian landscape. The picture is the same. On the way to Whitehorse, it was a sin not to stop at the town of Carcross for 300 people, where peaceful hunters and fishermen lived, and where there was even a school and a church, and even a miracle and miracles - a restaurant on wheels, where a real Japanese woman wrapped sushi with her own hands and cut sashimi. Having met one of these anglers, we talked about the fate of the locals over a lake trout barbecue, and a Canadian jack-of-all-trades told me about all the realities of the life of the leaders of the Redskins and their subordinates (by the way, not about the Indians, among such non-urban Canadians it is considered normal to invite a complete stranger to your place for dinner on the first day of your acquaintance, to introduce you to your family, to dine together, and also to give a basket of blueberries with you to hungry America). From Friday to Monday night, the entire neighboring reservation brings down in Carcross for a drink. It is forbidden to sell alcohol and drink on the reservations themselves. Well, of course, there is a lot of trouble later from vomit and drunken cleansing the holy land of the Chingachgooks. Therefore, the population kicks itself to squealing in the Canadian outback, enters into a fight with the locals, shits, fills all the tiny restaurants where there is booze. Of course, this is disgusting to the locals. I stopped a couple of times over the weekend at a roadside cafe opposite the reservation itself. It's like the feeling of being in a leprosy clinic and a sobering-up station at the same time. I will not go into details. Yes, one more detail. In sparsely populated (and therefore even more beautiful) Alaska, stingy with news, great grief happened that summer. In the small town of Huna, a guy shot and killed two police officers who stopped his car, which was speeding at a speed of 150 km per hour. The guy barricaded himself in his house, and the police negotiated with the killer for more than a day. It turned out to be one Indian who, before the murder, drank to the squeal of a pig for more than two days. Every fatherless policeman has two kids. One of those killed was also a red-skinned man.

The largest concentration of Indians in the United States is in northern Arizona along the Utah border. It's just that every second one is Iron Claw and Faithful Hand, or rather their Americanized and fairly fat descendants. The Navajo and Hopi reservations stretch for hundreds of kilometers. They are surrounded by a wire fence, which, although you can step over, but there is absolutely nothing to do on these reservations. For two nights we slept across from the Navajo Reservation in Monument Valley. The camp organized by the Americans is not on the territory of the reservation (America literally "removes" this land from the Navajo) has all the amenities: toilets, showers, full service for motor homes, a grocery store. The workers are only natives. There is also a camp on the reservation itself, right at the foot of the most beautiful outlines of mountains. But there are no toilets, no water, not even a banal barbecue grill. Simple and angry, a night in your own tent is $5. Probably because laziness. Or maybe because the Monumental Valley itself sets you up for a different, non-mercantile way of life: to contemplate the starry sky and at the same time walk in the bushes. The very project to make Monument Valley a historical monument was, of course, white Americans. The Indians only "accepted the project of the pale-faced, conferring under the Big Tree" (so it is literally written in the guide to the history of the Valley). Wise Owls and other Sly Snakes received hundreds of jobs, competitive salaries, tips, subsidies for project support, cleanup, security, and more. They still continue to live there, among the bizarre rocks drawn by nature from red sandstone.

Rare modern Indians can speak their own languages. And if they can, then they are insanely lazy. In voice and habits, they are as indistinguishable from Americans as the descendants of Scandinavians, Italians and Germans who emigrated. Some of them, especially those who work a lot with tourists, ridiculously decorate themselves with giant stylized silver and turquoise jewelry (as if emphasizing their national identity), which can be found on the shelves more often than cowboy boots. They are undersized in their mass and also tend to be overweight, as well as to a non-human image after half a bottle of strong. This is not the usual fullness, but losing all forms of obesity. I have never met a single red-skinned slender woman over 25 years old, not a single fit man. Every second child looks like a bun. Teenagers are all corroded slackers who play not football, but computer games, and hang out for hours in cheap fast foods. Some of the redskins own boats. But their rest on the water is about turning on pop music to the fullest and cutting through the waves on motorboats after a day's work. None of them, I am more than sure, have ever held or worked with oars. And the few that step into the cool water wet their bellies only briefly and then slowly return the bodies to the huge cars.

In one of the camps on Lake Powell, we wanted to know the exact way to a rare natural phenomenon - white limestone rocks with black "caps" called "mushrooms". The real Scalp Collectors worshiped this place, and it still bears an Indian name. The size 58 woman at the camp reception just shrugged her shoulders in surprise (the place was only 20 km from the camp and is known throughout the state) and advised to go to a nearby town, where "one smart woman in the tourist office knows everything." Fed on the unpretentious food of reality shows and serials, this bloated physiognomy has lived all her life in the neighborhood of famous places throughout America, and she absolutely does not care if she knows where it is or does not know. Laziness and some other amazing sense of superiority that can be read in every look, every offer of the Indians are simply indescribable. Like, you are here, "come in large numbers" on our land. And she has always been ours. And it wouldn't have been any worse without you.

If, God forbid, you decide to use the services of one of the White Eagles, be sure to discuss the price of the service in advance. In the city of Tuba, where 90% of the inhabitants are natives, and which is famous all over the world for the remains of dinosaurs in the open air, you will be invited with a smile like an old friend for a 10-minute walk in the footsteps of the Jurassic Park. And then, as if by chance, they will throw that this pleasure, minimally informative and completely unnecessary (walking without the so-called “guide” and with the “guide” is the same thing; these people do not bother with encyclopedic and curiosity) costs 20 or 30 bucks . If you leave the local store without a purchase, you will be bothered only with a devastating look, and the question “where is the nearest toilet” will be answered with centuries of silence by the red-skinned ancestors, keepers of the secrets of the mysterious rites of initiation into warriors.

And finally, about the faces that I was looking for and which I almost didn’t see. I have been to photographic exhibitions about the Indians and their history several times. I have always admired their peculiarly beautiful, sharp features, rebellious character in every wrinkle and piercing gaze. A modern photographer will have to travel hundreds of reservations before he manages to find at least a dozen faces that vaguely resemble warlike ancestors. Modern Indians are more like modern gypsies, just living on their land: sneaky, rarely loving to work and knowing exactly how to sneak away from work on time, loitering around and endlessly lazy. Among the redskins, of course, there are representatives from the world of arts, and excellent potters and goldsmiths, and historians who teach the history of their own reservations at universities, and in some states even politicians. But they are just an exception that proves the general rule.

Pecan leaf blight

Pecan leaf blight is a disease of the pecan tree, common in all production regions of the United States, caused by the bacterial pathogen Xylella 90 subsp. multiplex . [1] The pathogen was originally discovered as incidentally associated with pecan leaf scorch symptoms in 1998 year. [2] and was subsequently found to be endemic to the southeastern United States as well as Arizona, California, and New Mexico. [3]


  • 1 Master and symptoms
  • 2 Cycling of the disease
  • 3 Management

Master and symptoms of

to date of the study, 30 sorcerers of the puppies were identified, sensory, sensors. to pecan leaf scorch by bacterial. Some varieties appear to be more susceptible to infection than others, and resistant varieties have not yet been identified.

Pecan leaf blight symptoms appear in late spring with darkening and necrosis of terminal leaflets. These symptoms may be limited to leaves on one side of the shoot and may be present on all or some of the leaves. As the summer progresses, the symptomatic leaves eventually fall off, leaving behind the rachis, which also eventually falls off the plant. Symptoms may be limited to one or a few branches, but will spread throughout the plant after a few years. [4] Although the symptoms do not kill the trees, poor health eventually leads to lower yields. [5] There are other causes of these symptoms, such as pecan burn mites and drought stress, so laboratory testing is recommended for diagnosis. [4]

Disease cycle

Due to common graft cultivation practices, Xylella fastidiosa is often spread into new orchards by grafting infected graft material onto pure rootstocks or through infected rootstocks. [4] In addition, the disease is known to be carried by certain insects. So far, three leafhoppers and two salivary beetles have been shown to be capable of transmitting the bacteria to the pecan, with glasswing snipers and adult pecan saliva being thought to be the first vectors responsible for its spread. [6]


The primary management strategy for disease mitigation is to ensure that new gardens are planted with uninfected plants to reduce the initial inoculum that can be spread by insect vectors. This can be facilitated by a thorough inspection of trees from the nursery in the summer before transplanting to ensure they are asymptomatic. In addition, treatment of the scion with hot water just prior to grafting has been shown to eliminate the pathogen with a success rate of 97%. [7] Given the delayed nature of symptom development, this practice is recommended to reduce the chance of accidental transmission of bacteria through the graft. [8]

If symptoms develop in the garden, infested trees can be pruned and branched to eliminate the disease. It is recommended to perform this practice as soon as possible by cutting off a few feet behind the symptomatic areas. This method is only recommended for initial infections in the garden, on trees with terminal symptoms (i.e., far from the trunk), and is not guaranteed to eliminate the pathogen. It is best to completely remove the tree from the garden.

Another method of control is to reduce the number of disease-carrying insects.
