Arborist Care for City Trees

At Arborwell, our ISA certified tree care professionals service Bay Area and Seattle city forests of all shapes and sizes. The trees growing beside HOAs and apartments, near retail centers, corporate campuses, and parks, endure a lot of abuse. They suffer from their proximity to large buildings and swaths of pavement, damage from people and cars, drought and weather extremes, poor drainage, and untended pest infestation and disease. When city budget cuts leave city trees without the arborist care they so desperately need, it leads to serious consequences for both plants and people

The High Cost of Severely Neglected City Trees

The Arborwell team understands that neglecting the care of city trees costs far more in the long run than providing routine maintenance. Most of the emergency maintenance calls we attend to present far more in liability risk than proper tree care. Are these tree care issues putting your business at risk?

  • Dying, disease, and pest-ridden trees pose a serious safety risk. Left unaddressed, they can fall on vehicles, buildings, and pedestrians, leaving property owners and city governments liable for damage and injury.
  • Fallen limbs from trees with heavy overgrowth can damage power lines, causing outages. They can also block roadways, obstructing access. 
  • Unattended roots can crack and lift sidewalks and roadways, necessitating costly pavement repairs.

You can avoid these emergency issues with a minimal investment in timely care. At Arborwell, our plant health care experts can ensure your trees remain healthy and sustainable, benefitting the community. 

Maximizing the Benefits of City Trees

Trees are a key part of a happy, healthy urban environment. City trees clean the air and water, offer welcome shade, and reduce stormwater runoff. They serve as a habitat for area wildlife, combat the urban heat island effect, and provide a relaxing, natural ambiance for residents to enjoy. If only for a bit of routine maintenance, they could live much longer, healthier lives, increasing in value as they age. 

Keeping Up with Tree Care Responsibilities

Our knowledgeable arborists know that city trees don’t require intensive maintenance. In fact, they need less care as they mature. With a thorough evaluation, our experienced staff can develop a long term, proactive plan for your city trees with your budgetary needs in mind. We offer comprehensive services, including:

  • Pruning trees to reduce risk from fallen limbs
  • Cleaning up following storm damage
  • Clearing branches or trees that block or pose a hazard to structures and utilities
  • Removing and replacing dead trees
  • Quickly identifying and treating diseased or pest-ridden trees and mitigating spread
  • Addressing nutrient deficiencies
  • Removing invasive species
  • Improving species and age diversity of the trees on your grounds

You require preventative health checkups with your doctor annually. Trees need the same level of proactive care. Is it time to schedule a primary care visit from one of our ISA certified arborists? Contact Arborwell Professional Tree Management to schedule an evaluation and start caring for the city trees on your San Jose, San Francisco, Walnut Creek, Seattle, Palo Alto, Menlo Park, Hayward, or Oakland property today.

Proper Watering of Bay Area Landscaping Trees

Droughts are a frequent occurrence in the Bay Area, making care for your landscaping trees a challenge. Your trees provide many benefits, delivering cool shade, improving air quality, controlling water runoff and erosion, and increasing your property value. To safeguard their health and prevent drought conditions from making them vulnerable to pests and diseases, ensuring your trees have the water they need to survive this stressful time is essential.

Large Trees Need Deep Watering At Least 1-2 Times Per Month

Any tree species accustomed to regular watering can experience stress in drought conditions. Water-loving birches, redwoods, and maples are especially at risk. During a drought, you can transition mature trees that have been surrounded by a generous layer of mulch to a regimen of deep water irrigation 1-2 times per month. However, we recommend closely monitoring your trees. When temperatures reach or surpass 95 F, more frequent watering may be necessary.

Tips for Watering Bay Area Landscaping Trees

  • Look to age and species to determine frequency
    Our ISA certified arborists  can help you determine the best watering schedule for your trees. Young, newly planted trees require more water than established trees, up to 4 times per week in the summer. Native trees, such as California oaks, need far less water than non-native species, requiring only one or two deep soaks over the summer season.
  • Install irrigation carefully to avoid trunk rot
    Concentrating water at the base of a tree can cause trunk rot. To avoid this and get better root coverage, run your drip line in a spiral from the outer edges of the tree canopy, spiraling toward the trunk. Use a soaker hose or low-flow stream rotator heads, avoiding the use of wasteful sprinklers/sprayers.
  • Time your watering to minimize waste
    When irrigating your commercial property or residential complex, it’s best to water in the early morning or after sunset to minimize water evaporation.
  • Water to the proper depth
    Unlike grass, which has shallow roots, your trees require a deeper soaking. After watering, check the soil beneath trees, verifying it is moist (not soggy) to at least 18 inches deep.

Boost Your Irrigation Efforts with Mulching

Integrating wood chip mulch as part of your drought protocol can be a fantastic aid to your watering efforts, keeping moisture in the soil longer, and reducing water consumption by 10-25%. Adding a thick, 4-6 inch layer around your trees also protects roots from any extremes of cold and heat, as well as reducing the prevalence of weeds and grass that compete for water and nutrients.

Uphold the beauty and value of your property with the proper watering of your Bay Area landscaping trees. Contact Arborwell Professional Tree Management at 888-969-8733 to request an arborist consultation on your San Jose, San Francisco, Oakland, Livermore, or Palo Alto property today.

Fire Blight

Common Tree Diseases in California Cities

Do your usual tree management tactics seem to be falling short? The California climate, temperature extremes, and pollution can certainly do a number on landscaping, impacting tree health. However, the Arborwell team knows that disease may also be to blame. How can you distinguish environmental stress from illness? Check the trees on your California property regularly, watching for signs of these common tree diseases.

Anthracnose

Anthracnose is a fungus that affects a variety of plants and trees. It thrives in warm, moist conditions and multiplies very quickly during rainy spells, spreading through infected plant debris. Our plant health care experts identify it by the dark, sunken lesions it produces on affected flowers, fruits, leaves, and stems, which begin as small, irregular yellow-brown spots that darken and spread. Fortunately, with proper tree care from our knowledgeable arborists, anthracnose is not lethal.

Fire Blight

The Arborwell team frequently encounters this bacterial disease in the early spring. Though it doesn’t affect a wide variety of tree types, it is incredibly contagious and can cause significant damage very quickly. Fire blight attacks all parts of the tree, including blossoms, leaves, and branches, giving them a dark brown or black scorched appearance. It spreads through many vectors, including wind, rain, insects, and birds, and is frequently seen on California’s apple and pear trees. Left unchecked, it can kill a tree, necessitating removal and replacement.

Fusarium Wilt

Fusarium wilt is another widespread fungus we frequently see throughout the state. It is known for attacking food crops such as tomatoes and bananas and is one of many diseases affecting California palm trees. Fusarium oxysporum can live indefinitely in the soil without access to a living host and spreads easily, making it difficult to eradicate. The infection begins in the roots, interfering with water transport, causing lower (older) leaves to wilt and yellow. The disease then progresses to new growth until the plant eventually dies.

The Role of Pests and Disease

Experienced arborists know that weak and diseased plants are naturally more susceptible to pests. Infestations can quickly go from being an unsightly nuisance to a major problem, claiming the life of the trees on your commercial property. Watch out for these common offenders on sick or diseased trees:

  • Royal palm bugs
    These tiny, oval, yellowish bugs feed only on the freshly opened leaves of royal palms. Though they can make your palms weak and unattractive, if addressed quickly, we can save your trees.
  • Cabbage palm caterpillar
    Cabbage palm caterpillars feed on palm flowers, weakening the tree. Their reddish-brown larva also stains the tree, leaving behind an ugly mess. 
  • Palmetto weevils
    If young leaves on your palm trees are wilting and quickly dying, you may have palmetto weevils. If you don’t eradicate them fast, these black or red-winged pests can quickly kill your trees.
  • Gold spotted oak borers
    These tiny, invasive beetles kill oak trees and are fundamentally changing the landscape in the region.
  • Oak worms
    Oak worms feed on oak leaves, quickly consuming lush canopies to leave behind a scruffy, leafless tree. Caterpillars fall off trees en masse in May, littering patios, cars, and people.

Mature Tree Pruning

Mature Tree Pruning: Essentials for Proper Care

Mature landscape trees require meticulous care to remain healthy, structurally sound, and beautiful. Unfortunately, many well-meaning property owners unknowingly damage established trees, shortening their lifespan with improper  tree pruning techniques. Older trees have unique needs. To ensure the optimal health of large trees and maintain the aesthetics and value of your commercial property, it is crucial to learn these mature tree pruning essentials.

Proper Pruning Requires Arborist Expertise

Our arborists perform tree pruning with a thorough understanding of tree biology. We know that each cut impacts and potentially changes the growth of a tree, so no branch should be removed without good reason. Because trees store sugar within their dense crown of leaves, we are also cautious of over-trimming that could rob a tree of nutrient reserves, causing significant stress.

Reasons to Prune Your Landscape Trees

Routine thinning does not necessarily improve tree health. Instead, landscape managers should trim trees to correct existing problems or prevent issues from occurring. When should you prune your large trees?

  • Aesthetics
    Trimming can improve the form and enhance the beauty of your trees.
  • Cleaning
    Removing dead, diseased, or weakly attached branches reduces cleanup on your property and prevents potential damage and injury.
  • Thinning
    Thinning branches can increase the ability of light and air to filter through the tree canopy to the ground below.
  • Clearance
    If your trees do not leave adequate, safe clearance around landscape features such as buildings, walkways, roadways, and electric lines, it is beneficial to trim them.

When to Prune

It is safe to prune the trees on your Sacramento, Peninsula/Los Altos, Palo Alto, Burlingame, Hillsborough, or Redwood City property at any time of the year. However, our certified arborists know that trees heal better following pruning procedures performed before the spring growth flush. We avoid the heavy pruning of trees after this growth because your trees have spent a great deal of energy producing it, and heavy pruning at this time can cause significant stress, particularly in weak trees.

Our knowledgeable team understands that mature trees do not tolerate heavy trimming as well as younger trees, taking care to remove no more than 25% of the crown, or less, depending on age. When making cuts, we are mindful of making clean cuts without damaging bark, while protecting the branch collar, and subsequently, trunk tissue, upholding the tree’s ability to heal and thrive.

When trimming diseased trees, such as those with oak wilt, we know it is best to use caution. Our arborists avoid pruning during active transmission periods when the disease spreads more easily.

Avoiding Tree Pruning Dangers

Pruning large, mature trees is not a do it yourself job. It usually requires working from tall heights using power equipment. Our licensed, insured arborists have the skills necessary to manage these physically demanding tasks safely. We believe safety is no accident, using the necessary protective equipment, proper tools, and techniques to eliminate hazards on-site.

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.

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.
