Arizona Ash Tree Problems

Arizona Ash Tree Problems

With more than 65 known species in the state, it’s safe to say Ash Trees thrive in the Arizona climate. However, there are a few problems and diseases that can harm these trees.

Types Of Arizona Ash Trees

The following is a list of some of the most common varieties of ash trees found in Arizona:

  • Chichuahua ash – Fraxinus papillosa
  • Goodding ash – Fraxinus gooddingii
  • Fragrant ash – Fraxinus cuspidate
  • Singleleaf ash – Fraxinus anomala
  • Littleleaf ash – Fraxinus greggii
  • Arizona ash – Fraxinus vulutina (also referred to as ‘modesto ash’ and ‘velvet ash’.
  • Shamel ash – Fraxinus uhdei (also referred to as ‘tropical ash’)
  • Fantex ash –  Fraxinus velutina (also referred to as ‘Rio Grande ash’)
  • Green ash – Fraxinus pennsylvanica (also referred to as ‘water ash’ or ‘swamp ash’)
  • Raywood ash – Fraxinus oxycarpa

There are various positive features about the Arizona ash tree, but all things have a downside. The ash tree was labeled by Horticulturist Calvin R. Finch, Ph.D. as being ‘trash trees’ due to them being partly messy and only having a lifespan up to 30 years.

Ash Tree Characteristics

The Arizona ash tree sheds leaves after the growing season is over, making them deciduous. Of course, many tree varieties are considered to be a messy tree, but the positive side is that the majority of ash trees only shed leaves for a couple weeks. Additionally, the majority of ash tree varieties will produce seedlings one time per year (in large amounts), or throughout the year. This all depends on the gender of the tree, and which species it is. When it comes to having an ash tree, and you want your landscape looking clean you will need to rake on occasion.

Most ash trees grow very quickly, which is great for adding shade. However, this also has its downsides. The quicker trees grow, the more likely they are to have surface roots. Ash tree roots commonly grow near the surface anyway, but are more tolerant against rocky soil and alkaline. Watson and Gilman described green ash trees in a Fact Sheet, reporting the surface roots may “lift sidewalks, curbs, and be a nuisance when mowing”. Meanwhile, Finch quickly indicated the quick growth creates another downside, common with ash trees, “Unless they are pruned regularly, they can quickly grow into a tangled mess causing branch dieback.” You should prepare to have ash trees trimmed every few years, which promotes healthy canopy and branch structure growth.

If ash trees are not trimmed, it can lead to branches being weak and breaking when multiple trunks gather too close. This creates a hazard from structural failure. The best approach is to establish a single ‘central trunk’ during the tree’s youth. Depending on the variety of ash tree, they can range from 40ft to 50ft when mature, with some reaching over 80ft high. All ash trees will provide a round, full canopy with great shade.

Ash Tree Diseases

Similar to other plants, Arizona ash trees are also vulnerable to different types of disease and pests. These include different fungal infections, mildews, rust disease, leaf scorch, and many types of pests from carpenter worms and webworms to mites and borers. The Verticillium wilt is especially harmful as it is soil-borne fungus. There are regions around the country, especially in the Midwest, where thousands of ash trees have been killed off by emerald ash borer’s. However, Arizona ash trees have been lucky enough to evade this issue, so far.

You can learn more regarding the emerald ash borer at Emerald Ash Borer. When trees have poor environmental conditions, it increases their vulnerability to these type of issues, making it important to maintain the tree’s defense with proper fertilizing and watering.

Ash Tree Maintenance

If well maintained, ash trees are beautiful and lush. However, when ash trees are not properly cared for they can become a nasty sight, and increases the risk of tree disease and pests. Although there are ash tree varieties which are rather resistant to drought, the majority of them will require regular watering. The best setting would be flood irrigation systems. Therefore, if your landscape is not irrigated, you should use a garden hose to mimic this, and do a deep watering one or twice monthly.

If you are located within Arizona and you desire to have a healthy and great looking ash tree in your yard, you should prepare yourself for the increased water bill each month. You’ll also want to remember to regularly fertilize the ash tree(s), placing mulch down will also help. By applying mulch, you will increase the quality of the soil, as the organic matter will break down over time. However, mulch also assists with retaining the moisture, meaning watering less often.

Although Arizona ash trees are not the simplest tree varieties to care for, they can be well worth the extra work. When properly taken care of, ash trees will provide amazing shade, and enhance the overall landscape.

All You Need To Know About Fruit Trees In Arizona

All You Need To Know About Fruit Trees In Arizona

Arizona’s climate is ideal for growing a variety of fruit trees for the entire year. This post will cover a variety of topics related to fruit trees, including varieties, trees, climate factors and pollination.

Fruit Tree Varieties

It is certainly possible for one type of fruit to grow well in the desert climate while another fruit may never develop properly. It is undeniably beneficial to do research beforehand to know which fruit type will thrive in the valley of the sun. Producing the fruit can be pretty easy if simple Botanics are applied to the specific variety.

Selecting Fruit Trees

The best fruit trees are the ones that have a low chill requirement and great pollination, especially in southern Arizona. Deciduous fruit trees, for instance, will lose their leaves come winter. Examples of these will include:

  • Apples
  • Apricots
  • Peaches
  • Pecans
  • Plums

Climate Factors

Of course, a fruit tree could fail to grow if the prevailing environmental conditions are not favorable. It is very tough to correct any mistakes once the tree has been planted. Selecting the right tree, with conditions factored in, is vital.


If you want to produce fruit, pollen from the male parts of a flower must be transferred to the female portion. This makes fertilization a reality. Some fruit trees are self-fruitful, which means only a single tree needs to be planted in order to produce fruit. Some fruit trees, though, will require the presence of a second supporting tree. This allows for cross-pollination to occur.

Fruits That Thrive In Arizona

Here are a few fruit trees that grow very well in southern Arizona:

  • Santa Rosa Plum
  • Satsuma Japanese Plum
  • Gold Kist Apricot
  • Katy Apricot
  • Dorsett Golden Apple
  • Ana Golden Apple
  • Orient Pear
  • Leconte Pear
  • Flordahome Pear
  • Castlebrite Apricot
  • Flordaprince Peach

What Is Tree Pruning

What Is Tree Pruning?

Tree pruning is defined as a horticultural practice comprising of the selective removal of various parts of tree. These parts can include branches, buds or roots.

Why Prune Your Trees?

Since each cut can alter the overall growth of  the tree, no branch should be removed without reason. Typical reasons for pruning are the removal of dead branches, enhancing form or simply reducing the risk of falling branches. It is possible to prune trees to let in more sunlight and air penetration to the tree’s crown. In some cases, mature trees are pruned as preventive steps.

When To Prune Your Trees

Most regular pruning practices can be performed during any time of the year without much impact on the tree itself. Generally, wound closure and growth can be increased if pruning is done before the spring growth flush. Trees diseases, such as oak wilt, may develop when pruning wounds provide access to pathogens. Refrain from pruning any vulnerable trees.

Pruning Your Trees

Proper pruning is crucial towards developing a healthy tree with a robust structure. Trees receiving proper pruning measures while they are young will require less corrective pruning as they age. It is a must to create a sturdy structure of primary branches in younger years. Properly trained young trees should develop a strong structure with less corrective pruning needs as time goes on. For a lot of young trees, it’s suggested to keep a single dominant leader constantly growing upwards.

Pruning Palms

Most pruning is performed on palm trees to remove dead or dying fronds, flowers or fruiting clusters. On average, pruning is typically done about twice per year on a palm. Coconuts, for instance, can be pruned every 3-4 months. This minimizes the dangers of falling coconuts. Green fronds growing on palm trees should remain untouched. Pruning palms too often can result in attracting more pests and a slower growth rate.

Pruning Techniques

Different types of pruning may be necessary to manage certain trees. There are four pruning techniques listed below:

  • Cleaning: This involves removing dead or dying branches from the crown of the tree.
  • Thinning: This is a selective branch removal used to improve the tree’s strength and light/air intake.
  • Raising: Raising is removing lower branches from a tree, allowing clearance for people, vehicles, etc.
  • Reduction: This is done to reduce the overall size of the tree. Reduction can be done by pruning back the tree leaders and branch ends.

Arizona Ash Tree Growth Rate

Arizona Ash Tree Growth Rate

Classified as moderately fast growing, trees of the Ash species can grow between 18-25 feet in a decade. What can you do to ensure your Ash tree grows at this rate in Arizona?

Average Ash Tree Growth Rate

While most species will grow anywhere from 18-25 feet in a decade, as mentioned above, other species like European ash will grow at a slower rate. Typically, European ash trees will grow to a maximum height of 18 inches after a decade. Most Ash species will grow approximately 2 feet per year for the first part of their life when planted as ornamentals. These trees may grow slower when planted in a row with other trees.

These fast-growing trees are usually grown for timber and firewood due to their dense wood and short maturity time. Ash trees also make great ornamental specimens in sunny areas, featuring moist and well-drained soil. The growing speed of each tree will heavily depend on species and surrounding conditions.

Natural Germination Time

Members of the Ash genus will produce winged seed pods referred to as keys. These pods will typically ripen in early to mid fall. The seeds will not become viable until after they have been soaked and exposed to cool/cold temperatures. Most ash seeds will take at least 18 months to germinate if kept wet, in most cases. The pods will remain viable for up to 6 years as long as conditions remain favorable.

Seed Stratification

There is one trick to speeding up the ash seed growth: stratify the seeds in the refrigerator. This process will involve placing seeds in moist paper towels or sand, then leaving them in temperatures around 40 degrees Fahrenheit for 60-90 days. After stratification is complete, the seeds need to be placed in a spot where daytime temperatures hover around 85 degrees, and nighttime temperatures are closer to 70 degrees.

It is best to plant the seeds in the spring, if you live in southern Arizona. Seeds typically germinate within two months of stratification.

Time To Maturity

You must understand that not all Ash trees will reach maturity at the same time. Several factors, including sunlight and soil quality, can speed or slow growth time. On average, Ash trees can grow between 40-60 feet at maturity. Some species have been measured as tall as 80 feet at maturity. Growth to full maturity can take 16-60 years.

Growth Rate Vs Lifespan

These trees are commonly chosen by homeowners and new construction projects due to their growth speed. A high growth rate, though, can create more weak spots in the wood and can limit the tree’s lifespan. Ash trees can also lose limbs easily due to high winds.

Avocado Trees In Arizona

Avocado Trees In Arizona

Is it possible to grow avocado trees in Arizona? Yes, it is!

This post will cover:

  • Best avocado trees for Arizona’s climate.
  • Best site to plant the trees.
  • How to plant avocado trees.
  • Watering the avocado trees.
  • Fertilizing the avocado trees.
  • Pest control.

Best Types Of Avocado Trees In Arizona

There is a wide variety of avocado trees, but some will do better in different climates. With the extreme heat of the Arizona desert, choosing the right avocado tree is crucial. Mexican and Guatemalan avocado trees tend to do the best in the valley of the sun.

Avocado Tree Site Selection

This pertains to where you plan on planting your avocado tree. Choose an area that is protected from the wind and has fast draining soil. This means a sandy soil type is better equipped for avocado trees than clay. Make sure to prep the soil in the area before planting the tree. Mix in some compost to ensure available nutrients. The should end up being half sand and half compost.

Plant the tree in an area that receives sunlight in the morning and shade in the evening. Avocado trees do not enjoy being exposed to harsh sunlight during the hottest parts of the day in the afternoon. Try to plant your tree on the east side of your lawn.

Avocado Tree

Planting Avocado Trees

To properly plant an avocado tree, dig a hole 2 to 3 times the width of the container and the same depth. Before placing the tree in the hole, saturate the hole with water and wait for the water to drain completely. After the water has drained, you can now place the avocado tree in the hole.

Gently pack in the mixed soil, compost and sand around the root ball. Next, create a little berm or moat of raised soil surrounding the base of the plant with soil and fill it with water. This should be about 4 inches high, which helps contain the water so it can be delivered to the root ball.

Watering Avocado Trees

During the growing months (mainly spring), you will need to give the tree a good soaking at least once a month. The hotter months will call for a good soaking twice a month. Then, you will need to irrigate the avocado tree for a few hours to push the salt away from the root ball.

Fertilizing Avocado Trees

Standard fertilizers with salt or sodium should NOT be used for avocado trees. These ingredients can harm the tree’s growth. It is recommended to use fish emulsion at least once during the growing season. Fish fertilizers are safe and typically available at local nurseries.

Avocado Tree Pest Control

Thankfully, avocado trees do not have any natural pests since they are not native to Arizona. Check with your local nursery if your tree is encountering any sort of unexpected pest issues.

Caring For A Sago Palm Tree In Arizona

Caring For A Sago Palm Tree In Arizona

Sago palm trees are well suited for the unique climate in Arizona. Below is a how-to guide for sago palm tree care.

Taking Care Of A Sago Palm Tree

Ash trees are often a great addition to your yard when it is already filled with sago palms. Featuring large fronds, comparable in size to palms, these sago palms are cycads that are very closely related to conifers. Sago palms will grow in the 8, 9 and 10 zones of the USDA plant hardiness. Full mature sago palms can grow up to ten feet tall.

Planting A Sago Palm Tree

Where should you plant your sago palm tree? Well, these palms tend to grow the best in areas with a moderate amount of shade. If the plant receives an excess of sunlight, sunburnt foliage can occur. With partial shade, however, the leaves can grow larger. Sagos also need soil that drains well. Too much water, though, can cause issues with rot. The ideal planting conditions are a partly sandy site with a mix of compost.

Watering A Sago Palm Tree

You only need to water this plant when the soil is dry. Younger sago palms do appreciate regular irrigation. Typically, watering the plants every 5-7 days when there is little to no rainfall is ideal. Well established sago palms are usually drought resistant and will require rare waterings.

Fertilizing A Sago Palm Tree

Fertilizing the plant once per year in the spring time should be enough to keep it healthy. For this process, use one tablespoon per square foot of a 10-10-10 recipe for fertilizer. Put the fertilizer around the base of the palm, nearly 8-9 inches from the palm. Then water the fertilizer in. New foliage should appear as a healthy green color.

Sago Palm Tree Issues

These palms trees are extremely resistant to pests and diseases. Waterlogged soil resulting in root rot is one of the more common issues with sago palms. Properly watering the plant with a well draining soil should solve the issue, though. Sago palms can tolerate very low temperatures, but some foliage may die if the temperature drops below 25 degrees Fahrenheit.

Pruning A Sago Palm Tree

Pruning is really only needed as a decoration of the sago palm. You can remove the cone from the palm carefully as long as the growing point beneath it remains undamaged. If left in place, the cone could fall off as new foliage begins to develop. If older foliage becomes tatty, cut it close to the trunk as soon as the new leaves unfold.

Treating A Sick Sago Palm Tree

The sago palm is sick when it starts yellowing. When nutritional deficiencies are present, feed the palm houseplant fertilizer every month. If the sago palm is indoors, try hand picking them off or placing it outdoors, allowing natural predators to eliminate the yellowing.
