Arbor-wellness: Keeping Palm Trees Healthy

Most pictures of California include palms in the skyline. They have become an iconic symbol of the state. There is even one California based fast food company that feature palms in their logo and at all of their sites. The taller palms are easy to see in the skyline and remind us of sunny days and warm breezes.

For the most part palms seem to be easy to grow. They grow quickly, are fairly drought tolerant and handle most of our weather variances well. However, they do need maintenance and – in many cases, protection – from certain diseases and insects.

While we classify palms as a type of tree, they are very different from shade trees or evergreen conifers. They are actually closer related to grasses and as such, have very different needs than most other trees.

With palms it is important to make sure they are planted correctly. They need well drained soil, to be planted at the right depth and with enough space for their roots. Palm roots don’t extent too far though so smaller planters are acceptable for them. However, they will still need some water so the planter needs to allow for them to be watered when needed.

They also need regular fertilizer. Most of our soils in a city environment do not contain the components necessary for a palm to truly thrive. Palms receive a bulk of their nutrients from a very small area, so that area needs to be replenished on a regular basis. For most palms, feeding twice a year with a natural fertilizer blended especially for palms should be adequate. For larger palms like the Canary Island date palm, three times a year is recommended.

Watering is critical, but it also depends on the soil type and the drainage. IF your soil is sandy and drains well, watering every four to six weeks is usually adequate for an established palm. If the soil is heavy or doesn’t drain well, water less often. You should also consider improving drainage and the soil conditions if the soil is compacted and tight.

Protection from diseases. Several of the prevalent diseases on palms – like pink rot and diamond scale – are worse when palms are stressed or not growing vigorously. Proper water, drainage and fertilization that we discussed above will reduce the incidence of these problematic diseases. However, protective treatments should be made until the underlying soil, drainage or watering problems are fixed.

The remaining concern is insects on palms. While generally there are not a lot of pests that can bother palms, on occasion they will become infested. Aphids, scale, mealy bugs and mites are the most common insects we see. These don’t kill a palm, but they can weaken it and allow diseases or other problems to proliferate. If these have been a problem on your palms, proper treatments will reduce the problems and allow your palms to thrive again. In the San Diego area, there is a destructive newer insect that does kill palms. It is called the South American palm weevil. One of the largest insects we deal with, it attacks the upper growing tip of the palm and completely destroys it. Since this is the only growing part of the palm itself, the palm does not survive. Proactive treatments are the only possible solution.

If you are worried about the health of your palm trees, or you would like some advice on a maintenance plan for them, reach out to your certified arborist at Arborwell. We will be happy to visits your site and inspect them and develop a wellness program for their long term health and survival.

What Is an Arboriculturist?

Though many people are aware that an arborist takes care of trees, they may not know that arborists are people who have studied the science of arboriculture. Arboriculture refers to the careful selection, planting and management of trees and shrubs. An arboriculturist, also known as an arborist, is a professional tree carer who utilizes specific methods to ensure that the trees in their care are happy and healthy.

Arborwell Professional Tree Management employs certified arborists who use arboriculture practices when caring for the trees on your commercial property. Our experts use these scientifically sound practices to ensure that your trees are cared for through every stage of their long lives.

What does an arboriculturist do?

An arboriculturist adheres to key values when it comes to taking care of trees. They are important factors in creating an environment in which your trees can thrive. When an arboriculturist cares for your trees, they will follow these values:

  • Choose a healthy sapling. An arboriculturist doesn’t want to start on the wrong foot. They will help to select the healthiest sapling that will grow into a strong tree. An unhealthy sapling may grow to be an unhealthy tree and lead to future headaches for you.
  • Be aware of the environment the tree is living in. Selecting the right tree for your environment can be the difference between life and death for that tree. An arboriculturist must be aware of the climate challenges that make up the environment and carefully select the right type of tree to thrive in those conditions.
  • Change the type of care as the tree grows. A young tree requires vastly different care than a well-established tree. Saplings grow at an intense pace and need help with maintaining a strong structure, while older trees require less hands-on care and more preventative measures.
  • Have a strong base of tree biology knowledge. If arboriculture was easy, everyone would be doing it. An arboriculturist must have extensive knowledge of the biological functions and requirements of trees in order to create wellness and management plans.
  • Employ preventative care. An established tree with a strong base looks as though it can survive any challenge. But trees are very sensitive to change, whether it be because of disease, pests, or weather changes. Arboriculturists use wellness plans as preventative measures to ensure that a tree is as stress-free as possible.

Tree and Brush Removal Laws Vary by State and City

The laws surrounding tree and brush removal can be complex and sometimes difficult to understand. Laws vary between states and even cities, largely because of the wide variety of climates that occur across America and because of the important role that trees and brush play in local ecosystems.

Arborwell Professional Tree Management provides arborist and tree maintenance services for commercial properties, estates, municipalities and HOA’s and we are well versed in local laws concerning the removal of trees and brush. We can help you to navigate these laws and get you the permits you need to continue developing your property.

Why are tree removal laws so different?

Tree and brush removal laws are varied based on location because of different environmental factors and needs. In California, there are strict laws regarding vegetation within 100 feet of structures. The law states:

  • The first thirty feet from a structure must be clear of all dead plant material.
  • Tree branches must be ten feet from chimneys and other trees.
  • The last seventy feet must focus on fuel reduction, meaning lawns should be mowed regularly and areas underneath trees should be clear.

These laws aim to improve wildfire safety by reducing the chance of buildings and structures burning down. In places like Seattle, trees and brush play an important role in the ecosystems so laws revolve around retaining vegetation:

  • There are limits to the number of trees you can cut down.
  • You need a permit to remove non-native or invasive vegetation and plant native species.
  • You need permits to remove trees and vegetation in landslide prone and steeply sloped areas.

These are just a taste of the differences in tree and brush removal laws in California and Seattle. Before you go ahead with your property development be sure you are aware of your local laws and the permits you need to obtain!

Ask Arborwell about your local laws

At Arborwell Professional Tree Management our arborists are knowledgeable of local laws regarding tree removals and can help you understand them. Regardless of past experiences with tree and brush removal, we recommend to always check with your local government before removal as they will have the latest information on potential law changes.

Save yourself the trouble of accidental illegal removals and call one of our ISA certified arborists at 888-969-8733 today or contact us online to learn more about the tree and brush removal laws in your state and city.

common tree diseases

Arbor-wellness: Bacterial Leaf Scorch

I’ve been told my oak trees have bacterial leaf scorch, what is that?

Bacterial Leaf Scorch is a devastating disease of shade trees caused by a bacteria. The bacteria themselves live inside the tree’s water conducting tissue. They “cluster” inside the water transport tissue and essentially block water transport, which leads to the scorch symptoms.

The disease will slowly progress throughout the tree for up to a decade causing dieback and eventually killing the tree.

What trees are affected by it?

Symptoms and damage are usually most visible on pin and red oaks, but shingle, bur and white oak can be affected as well. It can infect elm, sycamore, mulberry, sweetgum, sugar maple, and red maple.

How does it spread?

Insects like sharpshooters, treehoppers, leafhoppers, and spittlebugs spread the bacterium from one tree to another. These insects feed on the xylem tissue and will inoculate the tree if they carry the bacteria with them.

Can you treat for this?

It is best to treat before the tree has Bacterial Leaf Scorch or in the early stages of it. Your Arborwell Arborist can develop treatment plans after determining the scope of the problem on your site. They can determine if preventative treatments or early curative treatments are required. If certain pests are prevalent, treatment to prevent their establishment may be recommended.

Also remember that a stressed tree will develop symptoms faster, so keeping trees properly watered and mulched are another way to help reduce the spread of this disease.

If you are concerned about bacterial leaf scorch, or other problems on your trees, contact your Arborwell arborist to help you create the most effective management plan for them.

Arbor-wellness: Cherry Bark Tortrix

What is the Cherry Bark Tortrix?

The cherry bark tortrix, is an introduced caterpillar pest in western Washington  and from British Columbia south to parts of Oregon coastal areas. It is found mostly on cherry, plum, and apple; but may also be found on peach, crabapple, pear, hawthorn, mountain ash and quince.

Why do I need to worry about it?

It is a growing problem in our area. It can kill trees outright through girdling the trunk. Typically, though, heavy infestations around the graft lead to dieback above the graft. The stress associated with an infestation can leave trees susceptible to secondary disease and insect problems.

How does it spread?

Cherry Bark Tortrix is a smaller moth, whose caterpillar stage does the damage inside the lower tree trunk. They overwinter in the trunk and emerge in the mid-late spring time frame. The adults lay eggs in cracks and wounds in the bark area in late summer. Large populations will kill the trees as they girdle around the tree. Initial infections will stress the tree and often cause a gummosis that exudes from the bark.

What is the best way to treat it?

Protection from these late summer infections is usually the best proactive treatment, but spring systemic treatments are also effective and should be considered if you are concerned about this pest. Your Arborwell Arborist can insect your trees and determine a treatment plan. Typically they include a treatment to suppress any existing problem, then an annual proactive treatment to prevent further infestations. Proper tree health is also important, so they may recommend nutritional feeding and corrective pruning if needed.

If you are concerned about cherry bark tortrix, or other problems on your trees, contact your Arborwell arborist to help you create the most effective management plan for them.

Arbor-wellness: Leaf Spot

I see dark spots on my maple leaves and many of them are falling off. Is this a problem?

Your maple probably has a type of leaf spot disease. Leaf spot is a term used to describe a wide variety of diseases affecting the leaves of ornamental and shade trees. The majority of leaf spots are caused by fungi, but some are caused by bacteria. Leaf spots on trees are very common. They often result in some leaf drop. When the leaf drop is severe, your trees can be at risk of suffering damage until they recover.

How does it spread?

Most spread by rain or water splashing on their leaves. They often overwinter on fallen leaves, so leave removal in the fall we reduce many of these diseases. There are many different leaf diseases and some require fairly specific treatment, so having a professional help identify a management plan is critical.

How do they affect tree health?

If you think of a tree as an energy factory, the amount of leaves and the time they stay on the tree greatly influence the amount of energy they produce and store throughout the year. (Think photosynthesis.) when a tree loses the majority of its leaves from a leaf spot disease, the tree cannot store enough energy over time and becomes more susceptible to other diseases or insects.

Can you treat this disease?

Yes, in cases where significant damage is expected, treating either before or during the infection is appropriate. Preseason protection is always the best, but options exist for treating early before the disease becomes widespread too. Typically, some nutritional feeding is recommended to help the tree recover from the stress of these leaf diseases.

What else can I do?

Some slight changes in how you care for your trees can help reduce the incidence of leaf diseases. Proper pruning to keep the canopy open is the first step.  Avoiding overhead watering on the foliage is another important step. Keeping your trees healthy is also important. Be sure to fertilize correctly, though. At Arborwell, we use a nutritional feeding program that is proper for your trees and your soil conditions.

If you are concerned about leaf spot or other problems on your trees, contact your Arborwell arborist to help you create the most effective management plan for them.
