The Value of Trees in an Urban Environment

More than half of the world’s population now lives in urban towns and cities. Due to socio-economic factors, this number is only expected to increase. In most situations, the rapid expansion of cities takes place with little if any planning, leading to disastrous consequences for nearby forests and green areas, increasing pollution, and decreasing the availability of food and other natural resources.

With tree planning and management, trees can reduce these adverse effects, even with the amplification of these issues from climate change. In fact, the value of trees and green spaces in the urban environment is so great that many areas are beginning to look at ways to increase their tree count. Just what makes urban trees and plant life so valuable?

The Environmental Benefits of Trees

Trees absorb carbon, fighting climate change
Mature trees can absorb hundreds of pounds of CO2 annually. Trees sequester and store atmospheric CO2, using it during photosynthesis to produce sugars for energy, and releasing oxygen as a by-product.   

Trees filter pollutants from the air
Trees clean the air, absorbing dangerous contaminants like carbon monoxide, ozone, nitrogen oxides, and sulfur oxides and filter out fine particulates like smoke, dust, and dirt.

Trees cool the air, decreasing the “heat island” effect
Strategically placed trees can reduce the “heat island” effect, cooling the surrounding air between 4 – 15 degrees F. This helps people feel more comfortable, reducing AC use and energy consumption, and offering energy savings of up to 30%. They also insulate against wind, reducing heating bills by 20-50%.

Trees and greenery regulate water flow
Healthy trees and greenery can help control water flow, thwarting runoff, and preventing flooding. One mature evergreen can intercept more than 4,000 gallons of water annually.

Trees increase biodiversity
Planting and caring for native trees and plants increases urban biodiversity, offering a safe habitat for plants and animals.

The Socioeconomic Benefits of Trees

Trees provide a healthier environment
Trees improve air quality, producing oxygen and filtering pollutants and particulates from the air, helping reduce the incidence of disease and supporting the health of urban populations.

Trees can contribute to food security
The fruits and nuts from trees can provide food for humans and animals or composted and used to improve the quality of the soil.

Access to green spaces improves mental health
Multiple studies show proximity to green spaces is strongly associated with improved physical and mental health, decreasing high blood pressure and stress, and contributing to a more pleasant neighborhood environment. 

Trees can boost property value
Planning to include trees in the design of your San Diego, Sacramento, San Francisco Bay Area, or Seattle urban property can increase its value by up to 20%, attracting residents, tourists, and businesses.

Types of Palm Tree Pests in San Diego

There is no shortage of palm trees in San Diego. Sadly, there’s also no shortage of palm tree pests. In recent years, invasive, non-native insects have taken on a toll on these icons of the West Coast, making it challenging to keep your palm trees looking their best. Which types of palm tree pests do our San Diego arborists find causing the most damage to area landscapes?

Red Palm Weevil

red palm weevil

The Arborwell team frequently encounters red palm weevils when compiling arborist reports. One of the biggest threats to area palms, these giant 1.5-inch red-brown insects feed on over 40 different palm species. They have caused millions in economic losses globally.

A delicacy elsewhere in the world, these pests are believed to have been introduced when they were brought into the U.S. for food. However, red palm weevils can fly about a half a mile per day, and they quickly spread through the region by flight and through palm tree sales. Difficult to detect, no one identified the escapees until landscapers noticed area palms slowly dying, the trees looking brown and droopy.

Red palm weevils are tunneling insects with a long, slender snout, which the female uses to penetrate the bark of palms to deposit her eggs. Once hatched, the larvae burrow deep into the tree, consuming it from the inside out, and leaving behind a foul-smelling mush-like substance. Because damage begins high in the tree, where new frond growth emerges, the sound of the gnawing insects often goes unnoticed until tree wellness suffers.

Our arborists are familiar with the signs of red palm weevil infestation, which we often encounter during routine trimming. Our trained professionals know to watch for signs of red palm weevils, including larval tunnels and feces within leaf bases in the tree canopy. We can help you quickly quarantine and rid your grounds of these invasive pests using traps and trunk injection treatments.

Polyphagous Shot Hole Borer

arborist services palm tree

Unlike the massive red palm weevil, polyphagous shot hole borers are small; only the size of a sesame seed! Though tiny, these beetles have decimated hundreds of thousands of trees in Southern California, including healthy palm trees. Polyphagous beetles were discovered in the late winter of 2012, infecting several backyard avocado trees in Los Angeles, and have since spread to surrounding areas.

The pests were possibly introduced via shipments from Southeast Asia, though their specific origin remains unknown. The pest cannot fly but can hitchhikes in landscaping equipment, tree waste, and firewood. Another outbreak occurred a year later, found to be a second species of polyphagous beetle, the result of a second introduction rather than a spread of the L.A. infestation.

Polyphagous shot hole borers attack dozens of landscape tree species, tunneling within. They carry Fusarium, a fungus causing fusarium dieback, which affects hundreds of species. Unlike red palm weevils, these wood-boring beetles do not eat tree bark. They lay eggs in certain species that serve as reproductive hosts, such as California, Fountain, Jelly, and King palms, among many others. Like tiny farmers, they also use the tunnels they excavate to grow Fusarium, their primary food source, cultivating it within infested trees.

Our arborists can quickly recognize the signs of polyphagous beetle infestation and Fusarium dieback, dubbed the shot hole borer-fusarium dieback (SHB-FD) complex. Property owners typically notice limb dieback from the fungus, which blocks the transport of water and nutrients to leaves. When we see tiny little pinholes in tree bark, with sawdust-like powder around the holes, we scrape back bark to look for the tiny beetle in its circular galleries. As ongoing trials using natural predators progress, we use tree injection treatments to exterminate the polyphagous shot hole borer, devising a customized tree care plan to protect your landscape.  

Are pests taking a bite out of your landscape? Arborwell Professional Tree Management can help you control many types of palm tree pests in San Diego. Contact us at 888-969-8733 to speak to one of our ISA certified arborists, or to schedule an examination of potentially infested trees today.

What Does Soil Drainage Have to Do with Plant Health Care?

Many plants suffer or die in soil that is too wet or too dry. Knowing what type of soil you have and how it affects the greenery on your commercial property can dramatically impact your chances of successfully growing healthy, beautiful foliage. Your soil varies depending on your region and even how your property is situated. For example, hillside properties almost always drain well, while bottomland can be extremely poor in drainage. There is also diversity in soil structure that influences soil drainage and plant health care needs.

How Your Soil Type Affects Your Plants and Trees

What do soil type and drainage have to do with plant health care? As with the value of commercial real estate, the key to plant health is often “location, location, location.” Soil drainage affects the availability of water and plant nutrients. Many commercial landscaping sites lack the ideal drainage conditions. Because each plant species has different nutrient and irrigation needs, understanding the soil type on your property can help you manage issues integral to plant health.

Common Soil Types

Do you know which of these common soil types you have on your Seattle or Bay Area commercial property?

  • Sand
    Sand particles are quite large, draining quickly. Because sand does not retain moisture or nutrients well, plants grown in this type of soil require more frequent watering and intensive plant nutrient management to ensure health.
  • Clay
    Clay particles are extremely fine, sticking tightly together when moist. Clay is packed with nutrients and holds water well, but drains poorly, making your plants prone to fungal issues. If water displaces air, your plant’s roots, which thrive on oxygen, can suffocate, and they may die. Because of its dense composition, it can be difficult for the roots of young plants to penetrate clay.
  • Silty soil
    Typically found along riverbeds and lakes, silt particles are between sand and clay particles in size. Silty soil is one of the most fertile soil types, because it retains nutrients and moisture well but drains more quickly than clay. 
  • Loam
    Loam is a mixture of sand, silt, and clay. Providing the benefits of all three types of soil, it is the ideal growing medium. Some loams possess a higher proportion of sand or clay by volume.

What Type of Soil Do You Have on Your Commercial Property?

Arborwell plant and tree health care services experts have identified these types of soil in our commercial landscape management service areas:

  • The Bay Area is fortunate to have soil made of clay with loam, including rocky clay loam in the hills and gravelly loam in the valley.
  • Seattle Area soil is primarily Tokul soil, which is quite rare. Tokul soil began as volcanic ash. It is one of the most productive soils in the world. Tokul features a surface layer of gravelly loam, rich with plant matter, a reddish middle layer infused with iron oxides, and a cemented, root limiting layer of glacial till 20-40 inches below the soil surface. Though its top layers drain well, the cemented glacial till layer has high water and precipitation storage capabilities.

Finding the Right Balance

At Arborwell, we can help you analyze your soil on your commercial property, identifying issues, and taking corrective action when necessary. Depending on the unique composition of your soil, we may need to employ solutions such as soil amendments, to correct drainage and nutrient issues impacting plant health. Because each plant species has different requirements, this can complicate the plant health care landscape. Fortunately, Arborwell experts are well-versed on the soil types in your region, expertly assessing the irrigation and nutrient needs of your plants to help you achieve the right balance.

Are drainage issues destroying the landscaping on your Seattle or Bay Area commercial property? Schedule a plant health care consultation with an arborist in your area. Contact Arborwell Professional Tree Management at 888-969-8733 today.

Plant Nutrient Management in Seattle

Improve Your Seattle Property’s Soil with Plant Nutrient Management

Your plants depend on the nutrients in the soil for long-term health just as you depend on the nutrients in the foods you eat. Macro and micronutrients fuel the growth and beauty of your landscaping. However, providing your plants with a balanced diet takes care. Just as with your own diet, there can be too little – or too much – of a good thing.

A Skilled Arborist is Like a Dietician for Your Trees

With proper plant nutrient management, you can protect your trees, meeting all their nutritional needs. Providing expert soil analysis and studying the condition of the trees on your Seattle commercial property, our skilled arborists can identify nutrient deficiencies in your soil that may threaten the health of your plants, putting them at increased risk of pest and fungal diseases. We can then administer the exact amount of missing nutrients, supporting the health of your trees while preventing unnecessary damage due to the application of excess fertilizers and soil amendments.

Feed Your Soil – And Your Trees

With the right soil amendments, you can safeguard the health of your landscaping, improving resistance to pests and disease and laying the foundation for a long, healthy, beautiful life. Our knowledgeable team can help you feed your soil, creating the ideal environment for your plants and trees by:

  • Adding composted material to existing landscaping annually.
  • Utilizing compost prior to new plantings.
  • Strategically mulching to reduce the need for watering, control weeds, and feed your soil.

Avoid the Dangers of Overfeeding

The ISA certified Arborwell staff understand the importance of balance, testing your soil before composting and fertilizing to avoid the application and cost of unnecessary amendments. We know the value of naturally obtained nutrients, choosing compost, mulch, and other superior organic supplements over chemical options. Our mindful practices safeguard not only your plants, but the planet, protecting nearby soil and area waterways from the overuse of damaging chemical fertilizers.

Promote the vibrant growth of your Seattle HOA, retail, apartment, office or estate property’s landscape with plant nutrient management. Contact Arborwell Professional Tree Management at 888-969-8733 and request an arborist consultation today.

leaves browning due to vert wilt

Arbor-wellness: Verticillium Wilt

We are seeing more trees this summer that look green and healthy one week and within a few weeks entire branches turn brown and leaves dry up, the most common cause of this problem is verticillium wilt. Verticillium is a soil borne root disease that usually infects through the root as they contact verticillium spores in the soil.

Many trees are susceptible to verticillium including, arborvitae, birch, crabapple, ginkgo, maple, oak, pine, spruce and tulip trees. What makes this disease so difficult is that by the time we typically see damage, the disease has spread too far and tree removal is usually the only option. Once a soil is infected it is very difficult to kill the spores, so it usually remains in the soil indefinitely. However, there are some ways to protect your trees and reduce the chance of infection.

My tree was looked good last week and now this week it has several branches with dead leaves, what’s wrong?

This is most likely verticillium wilt, which is caused by a soil fungus that can lie dormant in the soil for many years. When the roots of susceptible plants grow close to the spores, the fungus germinates and infects the roots of the plants through wounds or natural openings. The fungus spreads into the branches through the plant’s vascular system and at the same time, causes the plant cells to “plug” themselves. Once this happens, water can no longer reach the leaves and they wilt and die, often all along one or branches at a time. It often happens quite suddenly, although in some plants the leaves turn yellow or brown first.

Why is this so prevalent now?

That is a hard question to answer but yes, we are seeing more of this disease this summer and fall. Essentially, our trees are still recovering from the drought of several years back. Their root systems were compromised. The moisture this spring really encouraged new rooting and also encouraged more root diseases overall.

How can I be sure my tree has this disease?

On certain trees – maples and tulip trees in particular, elongated dead areas of bark, called cankers, may appear on diseased branches or trunks. On most trees with the disease, the sapwood of smaller branches is streaked brown or black, occasionally in other colors too. However, since not every tree exhibits this discoloration, testing tissue in a lab may be recommended to confirm the diagnosis.  

Will my tree survive?

Unfortunately, usually not.  There seem to be two forms of the disease, one in which plants die slowly over several years and another where they die rapidly within a few weeks. Trees that show minor branch wilt one year may show more the next year or may not show symptoms again for several years.

Is there anything I can do for the other trees on my property? 

There are ways to help protect your trees, particularly if they don’t show signs of the disease. First make sure the tree is not stressed – proper water and proper feeding are important here. Secondly, there are some good guy fungal species that do battle against this root disease and several others, too. The good guys inoculate onto the roots of a tree and fight and kill these fungal pathogens. (I like to use the analogy of probiotics that help our digestive system stay healthy.) But this process should start before verticillium wilt becomes established in the tree.

Our arborists at Arborwell can recommend a protective program for the trees that are susceptible on your site. Fill out the form below to get in contact with an arborist today!

Closeup of Psyllids

Arbor-wellness: Psyllids

When large trees lose their leaves in mid-summer, we tend to panic, and often for good reason. We tend to think of water problems or diseases as the main cause, but sometimes it may be a small insect that is hard to spot. Psyllids are small insects that suck plant juices and excrete sticky honeydew on which blackish sooty mold grows. Some species secrete pale or white wax masses, pellets, strands, or coverings called lerps. They affect many species of trees in our region, but the most common are Eucalyptus, peppertree, citrus, acacia, laurel and tipu or rosewood.

My eucalyptus trees are losing lots of leaves, what could be wrong?

There are several reasons why eucalyptus leaves drop their leaves in large amounts. If you see small, whitish “caps” on the leaves, this is a type of “psyllid” called “redgum lerp psyllid”. This is one many psyllid types that are common in our region.

What other damage can psyllids cause?

High psyllid populations reduce plant growth and cause tip damage, discoloration or dieback. Certain species can cause premature leaf drop. Excessive honeydew creates a sticky mess on cars and surfaces below trees.

Do psyllids damage other trees in my landscape?

There are over 160 psyllid species that occurs on landscape plants in California. Each kind of psyllid feeds only on one plant species or one closely related group of plants. Most psyllids native to California are relatively uncommon and rarely become pests. But some can cause extensive damage. These are generally psyllids that have become pests on trees that are originally from other countries. The most important tree damaging psyllids occur on acacia, eucalyptus, olive, peppertree, laurel and citrus.

I’ve heard about citrus trees dying or being taken out, is this the problem with them?

Well, sort of. A relatively new psyllid pest (Asian citrus psyllid) has been introduced into parts of California. The insect itself doesn’t kill citrus trees, but it can introduce a disease called “Citrus Greening” that is essentially fatal to them. If allowed to become widespread, it is feared the California citrus industry will be wiped out. Currently, the agencies involved are heavily involved in scouting, insect control and plant removal efforts in regions that are most affected. Being vigilant about scouting and controlling this pest when found is very critical.

What can I do?

Your Arborwell arborist can identify locations where Asian citrus psyllid, Redgum lerp psyllid (or other types) are doing the most damage and recommend a treatment program to recover your trees and to keep them healthy. They can also recommend a proper plan for citrus trees on your property if you are close to an area affected by Asian citrus psyllid.

Fill out the form below to contact an Arborwell arborist and find out more about Psyllids and what we recommend for preventing damage and for helping trees recover if they have been attacked by high populations of Psyllids.

Request Tree Loss Reports in Storm Season

Big storms can be rough on your trees and cause issues that result in tree loss or heavy damage to trees. It is likely you will need to request tree loss reports during storm season and for that you require the help of one of our ISA certified arborists. At Arborwell Professional Tree Management, we can provide you with professional tree care and assessment to make sure your property recovers after storm season.

In Sacramento, San Diego and Seattle, our arborists can assess the trees on your commercial property or estate and provide you with arborist reports, which will help you to understand your options following damaging storms.

Why are tree loss reports important?

Our goal is to help your trees recover after they are damaged, and that’s why requesting a tree loss report is important for your property. These reports can help you to understand what damage storm season has done to your trees, what steps you need to take to recover and estimate what the cost of recovery is.

Most commonly people associate storms with broken branches and uprooted trees, but they can also cause fires, exacerbate disease and instigate other accidents. A report from a certified arborist does more than just inform you of the damage on your property, it can also be:

  • A way to obtain a permit for cases where you need tree removal. Many cities have strict removal laws that require official arborist reports.
  • An important document for insurance claim purposes.

When your property has been hit with a storm, Arborwell is here to help you recover with professional care from our certified arborists. We will nurse the trees your property back to health when we can, acquire permits for removal when there is no other solution, and safely remove trees that can not be revived.

Large Tree Care Challenges

The Challenges of Large Tree Care

A large, well established tree can present many challenges that the average person may not be aware of. Arborwell Professional Tree Management has ISA Certified Arborists that know how to address the needs of mature trees and can help you maintain these beautiful works of nature.

When it comes to large tree care, trust Arborwell to keep your trees healthy and looking their best. We know the challenges they can pose, and our experts have the experience to care for your trees.

Tree Trimming Is Crucial

With larger trees always keep in mind your local tree requirements. Trees must be trimmed to a certain distance from sidewalks, driveways and especially electrical lines. If a tree is planted too close to these things and it can’t be fixed through trimming, it may need to be moved to a new location. Our arborists in your area can educate you on local requirements and what options are available.

Its also important to know that mature trees require regular trimming to get rid of dead branches, diseased areas and to make room for new growth. With larger trees, it is vital to maintain the weight of branches. Trimming can help to avoid snapping and breaking of larger branches. Arborwell arborists know how to properly trim trees so they stay at optimal health.

Be Smart with Water Use

There is a big difference between the water needs of young trees vs old trees. While a young tree needs frequent watering as it is growing very quickly, larger trees benefit from less frequent, yet deep and soaking irrigation. The best form of irrigation for a large tree is soaker hoses, which provide slow watering. Speak with our arborists about what type of irrigation is best for your tree.

Be Vigilant about Pest Control

Large trees have much more foliage than smaller trees and it can take longer to notice pest infestations. Because larger trees grow much slower and it can be more difficult to identify pests, there is a greater chance of devastating infestations. Our arborists know how to identify and prevent pests from damaging your trees.

Choose Arborwell For Your Large Tree Care Needs

Arborwell Professional Tree Management knows how to take care of your mature trees. We know that larger trees can have a unique set of challenges and we want to educate you on how to properly take care of them. Call us today at 888-969-8733 or click here to visit us online and request an estimate.

What Do Trees Have to Do with Landscaping?

Trees are an incredible asset to any landscape. They benefit our communities and environment by cleaning the air, providing protection from the elements and creating jobs. The next time you’re out, take a few minutes to appreciate the beauty of your neighborhood’s trees.

Let’s discuss the main reasons why trees are important for landscaping. You will be surprised at how much these plants have to offer our health, wellness and environment.

Trees are Aesthetically Appealing

Trees are visually beautiful. Some have lived on our planet for thousands of years and tell stories through their branches, leaves and bark. Some families plant trees for sentimental reasons, such as the birth of a child or the death of a loved one. As the tree grows, it represents that individual. Trees are alive, which adds to their beauty and tranquility.

They Provide Privacy and Sun Protection

Many homes today are built in busy neighborhoods, and the best way to create shade and privacy is by planting trees. Their structure blocks noise, light and unsightly views. Plus, their shade protects people from the sun’s rays and helps homes and businesses consume less energy. By planting trees strategically, homeowners can enjoy more private, efficient homes.

They are Natural Food Producers

Thanks to fruit-bearing trees, both humans and animals can have fresh food to eat. Some of the most popular tree-borne foods in California include apples, cherries and citrus fruits like oranges, lemons and limes. Even in the winter, some trees continue to produce nuts, flowers and berries for birds and other wildlife.

Trees are Homes for Animals (and Children!)

Trees provide shelter to many different animals. Birds build nests on their sturdy branches, while squirrels build dens or dreys in which to raise their young. In fact, some animals need the forest to survive, including the tree kangaroo, pandas and orangutans (although you won’t find these in our California trees!). Kids, too, love to use trees to build treehouses and forts.

Cleaner Air and Water

Trees absorb pollutants and convert carbon dioxide into oxygen. Perhaps that’s why deep breathing is often associated with trees and nature. Moreover, trees prevent water evaporation and decrease water runoff. These benefits work together to produce healthy water with fewer pollutants and reduce flood damage and erosion.

There is no question that trees are an essential part of human life and existence. The next time you are looking to spruce up your yard, look no further than planting a new tree! For questions or information in regards to removing, replanting or managing the trees in your landscape, contact Arborwell today at 888-969-8733 or fill out our contact form.
