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.

Arbor-wellness: Pear Rust

My Pear tree is losing leaves right now and I notice these yellow/orange spots on the leaves and twigs too?

That is most likely a disease called pear trellis rust. It is one of several leaf diseases found on pear trees specifically. It can be a serious problem if not treated. The first step is to remove the fallen leaves and twig because the spores found in those help to spread it.

Is this a serious problem? It seems to be getting worse each year?

Pear trellis rust can be a serious disease and it often will impact the health and survival of pear trees. Stunted growth, thinning in the canopy, and branch dieback will occur after several consecutive years of infection. In areas where the disease is prolific, it can eventually cause death of the pear host. Though juniper plants are part of the disease cycle, they are not normally harmed by the disease.

How does it form?

One unique thing about most rust diseases is that they require a second type of host plant in order to successfully establish and reproduce. Without the second host you won’t have the disease on the desired plant. In this case the secondary host is juniper plants. Junipers planted within 1,000 feet are probably acting as the second host. Spores produced from the gall-like infections on the junipers travel to the pear trees in early spring by wind and rain. They infect new leaves as they emerge on the tree. In late summer, fruiting bodies emerge on the underside of leaves and on twigs, which then transfer the disease back to junipers.

 Do I have to remove my junipers?

That is the easiest way to control this disease on Pear trees. Remember though that if neighboring properties also have junipers, these plants may also be an alternate host if they are planted close enough. Another option is to replace your existing junipers with a variety of juniper that is resistant to the disease. These include – AmiDak, Bar Harbor, Blue carpet, Blue star, Winton’s Carpet and Juniperus communis ‘Aurea’ and J. communis ‘Compressa’ .

Can I keep my existing junipers and still control this problem on my Pear trees?

There are management techniques which involve timely treatments of the pear trees in the spring, usually more than once each season. Supplemental system treatment in the fall helps to prevent the disease as well. You can also prune out the galls on the junipers in early spring (Before April 1st), but they are hard to find and don’t look anything like the disease when you see it on Pear trees.

If you are concerned about Pear trellis rust on your pear trees, contact you Arborwell arborist who can evaluate the trees and recommend a program for them.

Arbor-wellness: Leaf Scab

Leaf Scab becoming a problem again.

Leaf scab diseases are a type of fungal infection that affect the leaves of apple, hawthorn and crabapple trees primarily. There is more than one fungal organism that creates this disease, but how they attack a tree and the treatments for them are very similar, so we will simplify the discussion by calling them leaf scab diseases.

Apples, crabapples, and hawthorn all can be affected by this disease, as well as some pear tree types. Out breaks are more severe after a wet, cool spring.

The fungus develops in the early Spring after spores are produced and distributed by wind and rain.

These spores infect newly forming leaves causing small brownish-green lesions on the young leaves. Once established on the new leaves, new spores are form and the process is repeated. As the disease develops on the leaves, the infected areas change colors and spread, until most of the leaf is affected and it falls off. Fruit can be affected too and even flowers may show symptoms. The fruit will become deformed and fall off prematurely.

Some varieties of flowering fruit trees are resistant and it is important when planting new ornamental hawthorn, crabapples or pear that you select the right varieties.

Older varieties are often most susceptible and need regular treatments to prevent early leaf fall. While it typically doesn’t kill the tree outright, the lack of leaves reduces the health and vigor of the tree and makes it more susceptible to other problems.

Arborwell has successful and cost-effective preventative programs available as well as “rescue” type programs that may be needed in certain situations.

Your Arborwell arborist can determine if this is a problem in your landscape and recommend an appropriate program for you.

Arbor-wellness: Sycamore Scale

When sycamore trees fail to thrive, we often look at leaf diseases like anthracnose and powder mildew as the major culprits. While these diseases are easy to spot, there is an insect that is much harder to see that often times contributes to sycamore problems. Sycamore scale is a small (1/16”) scale that feeds mostly on leaf tissue. This reduces the vigor and overall health of the tree. When sycamores are weaker they tend to get leaf diseases worse, which continues the downhill spiral of tree health.

These tiny scale insects overwinter on the bark and in the duff below the tree, then move to the leaves during the early spring. As they establish on the leaves they begin feeding and reducing the ability of the tree to produce and store energy in the form of sugars. When they are quite established, you can often see little “pinpricks” on the leaves as you look through the canopy. Left untreated, the tree will slowly begin to decline.

While unchecked infestations of Sycamore scale typically do not kill a tree outright, the trees are weakened enough that other diseases more easily attack both the leaves and the twigs. Excessive leaf drop from leaf diseases and twig dieback from branch diseases can become problematic season after season.

A good program for preventing diseases, regular nutritional feeding and proper watering should also include insect prevention to keep these tiny scale insects from becoming a problem. If you are concerned about your sycamore trees your Arborwell arborist can inspect and develop a program that encourages a healthy tree and discourages insects pests like Sycamore scale.

Arbor-wellness: Aphids

Aphids are a problem again.

This year’s mild winter and wet early spring has encouraged many insect pests so far this spring. One of the worst types are aphids, which seem to be abundant already. There are many types of aphids and they attack many of our most common and popular trees including: Crape myrtle, crabapple, birch, hackberry, hawthorn, maple, oak, strawberry tree, tulip tree and of course roses, too. Aphids produce an inordinate amount of a sticky liquid called honeydew. With the population of aphids so abundant so early in the season, it will be very important to protect trees soon if you have not done so already.

Slowing down aphid populations after they have become a messy problem is possible, but is usually more costly and usually involves washing off sidewalks or paved areas too. To protect your trees from aphids or other pests, fill out the form below to contact your Arborwell arborist for a comprehensive protection plan.

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.

Arbor-wellness: Keep Adelgids away from your Hemlocks

What are these cottony looking white things on my Hemlock? 

Most likely they are adelgids. Adelgids are similar to aphids and can be very devastating in large numbers. They prefer Hemlock trees but are also found on other conifers like Douglas fir, larch, pine and spruce. They can produce white, cottony tufts on bark, branches, twigs, or needles. 

Will they harm my trees?

When present in large numbers, adelgids may cause yellowing and early dropping of needles and dieback of terminals. They can retard or kill trees, although healthy plants can usually tolerate small adelgid populations.

Can I get rid of them?

When the population builds high enough, there are ways to treat your conifers to reduce the populations. Treatment now is important if the populations are causing problems. Otherwise preventative treatments in the fall or early spring will help.

What can I do to help my tree look better?

Proper nutritional feeding and avoiding tree stresses – like lack of water or even salt build-up, will help. On conifers it is important not to over feed them and produce excess growth. At Arborwell, we use a very specific program that has the proper balance of nutrients for each type of tree. If you suspect salt may be a problem, we can identify how bad the problem is and provide cost effective solutions for that.

Fill out the form below to contact your Arborwell Arborist today and we will be happy to check out your hemlock – and all your conifers – to keep them healthy, now and for the future.
