Month: May 2015

In early 2015, Governor Kate Brown declared a state of drought emergency in counties throughout Oregon. This is the first drought in the state since 2004. Drought can devastate agriculture, threaten livestock, and deplete natural resources. Another potentially major consequence of drought is compromised tree health. As we head into what wildfire experts are saying could be the driest summer in twenty-five years, it’s critical to preserve your own trees by brushing up on Portland tree care for drought.

Portland Tree Care: Tending to Your Trees During a Drought

1. Recognize Signs of Tree Stress

To properly mitigate the risks of drought, knowing the symptoms of tree stress is a good place to start. The first, and perhaps most, devastating damage occurs long before any apparent signs of trouble, in the form of root damage below the soil. In an attempt to amend the imbalance of this root loss, the thinning of the tree canopy may occur.

Evergreens demonstrate stress through the discoloration of their needles, sometimes turning brown at the tips, progressing through the needle towards the twig. At other times needles may turn yellow, red, or even purple. Deciduous trees may acquire “scorch,” in which leaves brown between veins or on the outside edge. Other drought stress symptoms may include leaves that wilt, yellow, and curl.

A side effect of drought is the onslaught of unscrupulous pests and diseases, including boring insects and fungal pathogens. Stressed trees go through chemical changes that attract opportunist pests. A tree weakened by drought provides easy access for infestation and pathogens.

2. Caring for Trees During Drought

While providing Oregon tree care services, we’ve seen a few common mistakes among well-meaning homeowners hoping to nourish their trees through dry spells. A common mistake is watering at the base of a tree, which is not where it finds its nourishment. Another is fertilizing during signs of drought stress, which can cause root burn. Instead, refrain from fertilization during drought, and water beyond the tree’s drip-line to reach the full expanse of the roots. Here’s a quick rule of thumb: Look at the height of the tree, and imagine roots growing two to four times that distance down into the earth. So watering farther around the circumference of the tree will help ensure that it is thoroughly nourished.

It is also important to make sure that moisture reaches twelve to eighteen inches below the surface—otherwise, the tree will not be able to absorb enough water. You can use a soil probe to help you determine when this has been accomplished. To retain moisture between watering, layer four or five inches of organic mulch on the soil surface, six inches from the trunk of the tree. Remember to also properly prune away dead or infested branches to improve the tree’s overall health. Prioritize watering young or new trees, trees that have recently received root injury due to construction, and trees that are growing in a restricted root zone, such as next to a sidewalk.

Tree watering is important all year round. In April to September you should water about three times a month, and in October through March water one to two times per month.

Despite the wealth of information on tree care it may still be challenging to determine the state of your trees in a drought and what steps to take to preserve the life of the tree. Fortunately, our Portland certified arborists are ready to help you mitigate the early and unnecessary death of a tree. Even the most caring amateur homeowner may fall short in tree care during challenging seasons. Contact us to arrange for consistent tree care during this hot, dry summer.

The Pacific Northwest sometimes sees extreme weather, and windstorms with gusts in excess of 60 mph are not uncommon during the stormy part of the year. Such high winds take their toll sending heavy limbs, debris, and even entire trees crashing down, potentially damaging property.

Recently, a woman posted a picture on our Facebook page showing a tree that had fallen onto her house from the neighbor´s property. She explained her confusion about who was responsible for damage from fallen trees. In this post, we’d like to explore the nuances of this situation and attempt to provide some clarity about who is responsible.

As Portland certified arborists, this isn’t a new circumstance for us. In the course of providing Portland tree removal, we’ve seen plenty of neighbor disagreements about fallen trees. In every such circumstance, the first thing to consider is homeowners’ insurance. “Healthy” is a keyword when seeking tree damage coverage under homeowner policies. When a healthy tree falls it is considered an act of God or Nature, and your homeowner’s insurance will cover the cost of damages to your property (minus the deductible and within the provisions of your policy). If the fallen tree is not considered healthy, you face an additional layer of complexity.

Portland Tree Care Experts on Tree Damage Liability.
Let’s take a look at insurance coverage in various possible scenarios.

Your tree falls on your house. Your homeowner’s policy should cover this; however, you should be aware of your policy coverage limits. Chances are that you will have to pay a deductible before coverage kicks in. Your coverage likely includes your main home, garage, sheds, and other outbuildings. If structures have been damaged, the policy should also cover debris removal.

Your tree falls on your neighbor’s house. Under most conditions, your neighbor’s homeowner’s policy will cover damage to their property.

What about the damage that could have been avoided? As a homeowner, it is your responsibility to maintain your property, including your trees. If your trees have existing damage such as visible rot and don’t take care of it, you could be deemed liable if the tree falls.

Be a good neighbor. Avoid liability and prevent neighbor bickering; maintain your trees and regularly inspect for damaged branches, disease, and rot. Of course, as Portland tree care experts, we are available to help in this and all other aspects of tree maintenance. Additionally, we consider it good form to offer to pay for or split your neighbor’s deductible if your tree damages their property. There is no guarantee they will do the same for you if the situation is reversed, but in our experience, it is best to give them the benefit of the doubt.

On the other hand, if you see that your neighbor has damaged or rotting branches that could potentially harm your property, it is advised to write your neighbor a friendly letter to let them know and to ask them if they could remove or trim the tree in question. You can also send a copy to this letter to your insurance company. The goal here is to kindly remind neighbors that if their unhealthy tree causes damage to your property, they could be liable.

Everyone here at Urban Forest Professionals is here to help as well. Our arborists can give a thorough and professional inspection, including diagnosis of potential problems. We can then remove damaged and diseased branches/sections, relieving you of any potential liability.

Remember—you are not liable for any damage that your healthy trees do to your neighbor’s property, but this only applies to healthy trees. You can be held liable if regular maintenance could have prevented the damage. Therefore, it’s best to arrange for regular tree care. Call us today about a tree inspection; by ensuring the health of your trees, you could be saving yourself hundreds of dollars on damage liability down the road.

Spring is here, and many people are thinking about tree planting, whether to add more shade or to replace trees that have been removed. As Portland certified arborists, we consistently field homeowners’ questions about replanting options. After arranging our Portland tree removal services for a tree lost to winter storm damage or disease, our customers often hope to replant another tree in the same spot. However, replanting is not as simple as it may seem. It’s important to choose a tree that will thrive in your available space. Moreover, city law may restrict your replanting options. Read on for our tips on replanting.

Tree planting is an area of urban arboriculture where major and costly mistakes are often made. The two major problems are 1) Choosing the wrong tree, and 2) Putting it in the wrong place. When choosing a tree, think about its preferred growing environment, its mature size, disease concerns, and other factors. If you’re unsure about whether a certain species will work, arrange for a tree consultation with one of our arborists.

Once you’ve found a species that will fit well in your available space, be picky about selecting the right specimen at the nursery. Our blog post on choosing a tree like a pro has advice on how to buy a healthy tree. Ultimately, when it comes to Portland tree planting, the ideal approach is to work with an experienced arborist who can help you select and plant the new tree.

Municipal restrictions are another area of concern when replanting trees. As the homeowner, it is up to you to be aware of local restrictions and regulations, which do vary around the Metro area. Portland, in particular, has some rather tight guidelines that could lead to a fine if not closely followed.

Portland Tree Planting Regulations

Street Tree Permits. If you intend to replant a street tree in Portland, you will need to get a permit that approves the tree type and size. To determine if a tree is considered a street tree, follow the City of Portland’s online instructions, which direct you to PortlandMaps.com to locate the tree. Basically, if more than 50% of a tree’s trunk is in the public right of way, it is considered a street tree.

Planting in your Yard. Although Portland has restrictions about what kinds of trees can be removed, the possibilities are endless as to what kinds of trees that can be planted in your yard. We recommend that you take a look around and see what you like and don’t like about the existing trees in your neighborhood. A professional arborist or horticulturalist can help you make an informed decision about what kinds of trees will grow best in your intended location.

Permits. In Portland, permits are needed for pruning, removing, and planting street trees or trees on commercial property. If you do not get a permit, you could be subject to fines of up to $1000 per tree, or $100 per inch of diameter—even if the arborist never told you that you needed a permit. At UFP our certified arborists can help you attain the necessary permits.

Mitigation. Some local municipalities, such as Lake Oswego, require that homeowners replant a new tree when an old tree is removed. This practice is referred to as mitigation, and it comes with its own set of city regulations. For example, in Lake Oswego no mitigation is required for trees that have been removed because they are hazardous or dead. Mitigation is required when a tree has been removed from a Lake Oswego right-of-way. Our Portland certified arborists can help you create a mitigation plan for tree removal.

Replanting for other reasons. The trees in our urban landscape provide both economic and environmental benefits. Mature trees add property, clean the air by producing oxygen, and provide habitat for nesting songbirds, among other benefits. The average lifespan of an urban tree is only 10 years, and most trees don’t reach maturity until 20 years, illustrating that maintenance is important to extending a tree’s lifespan. These numbers also emphasize just how much replanting actually goes on in an urban environment.

Whatever your reason for planting a new tree, we’d love to help. Our Portland tree services include consultation, tree sales and tree planting. For $300, we will take care of the whole process, from tree selection to planting. Our trees are premium stock; as such, we guarantee their health for three years against everything except vandalism and drought. Call us today about replanting a tree in your yard.
