Is My Tree Dead?

Wednesday, March 2nd, 2016

Trees provide shade, help freshen the air, and even add value to your property. We all want our trees to stay strong and healthy, but what should you do if you think one of your trees might be dead?

Dead trees don’t just look unattractive, they can actually pose a safety risk. Dead trees are more fragile. They drop branches easily and may even fall completely if not taken care of properly.

Today, I’ll show you how to tell if your tree is dead, and what you can do to keep your home, property, and family safe.

What Causes Trees to Die?

Trees live hundreds of years, right?

Many of them can, but damage and diseases can unfortunately kill a tree prematurely. In an ideal world, you’d notice the warning signs early on.

When a tree is dying, the cause of the problem usually starts underground with the roots and soil. Luckily, you can often see signs of tree death and disease above ground.

Here are some of the most common reasons why trees die:

Too Much or Too Little Water

Making sure your tree gets enough water is especially important when it’s young. Too little water can dry a tree out, while too much can drown it.

How much water your tree needs depends on the type of tree you have and where you live. The Arbor Day Foundation has some helpful tips for how much to water your tree at each stage of its growth.

Contact your local certified arborist if you have more questions about how to water your tree.

Changes in the Soil Grade

Changes in the soil level around your tree can affect how much water and nutrients the tree can absorb. That’s because trees’ primary feeding roots are usually located in the top six inches of soil. Changing the soil grade by even just a few inches can create a problem.

If you’re thinking of adding soil to your yard, be careful. Avoid adding too much near your tree if you can.

Root Damage

Trees need their roots to absorb nutrients and even remain standing. Big trees have strong, sturdy roots, but even those roots can be damaged.

If you have frequently driven over or parked on a tree’s roots, there’s a chance they were damaged.

Not only can the weight of a car damage roots, but all that weight also compacts the soil beneath it, making it harder for the tree to get the water, oxygen, and other nutrients it needs from the soil.

Pouring concrete, laying asphalt, or paving over tree roots can cause similar problems. If tree roots don’t have room to grow, or something is preventing them from feed from the soil, you may have a problem.

Improper Planting or Transplanting

Young trees are especially sensitive, so planting and transplanting them can be risky. A couple common mistakes are:

• Digging a too shallow or too deep hole
• Packing the soil down too hard after planting

Both can smother the tree and prevent proper root growth.

Tip: Any time you plant or transplant a tree, be careful of the root ball (the tangle of roots at the bottom of a young tree). If there is burlap or twine tied around the roots, remove it carefully. Then, gently loosen and separate the root ball just enough to help the roots spread out before you place the tree in the ground.

What Does a Dead Tree Look Like?

The warning signs will be slightly different depending on what type of tree you’re dealing with. Usually, though, you’ll be able to tell if there’s something wrong.

What should you look for?

Falling Leaves or Needles

A tree that is dying or dead often loses its leaves or needles very quickly and suddenly. Or it has no foliage whatsoever, even during a time of year when it should.

Changing Colors

Unexplained discoloration of the foliage is another common sign of stress or disease — usually one of the first ones you’ll notice.

Brown, multi-colored needles are a common sign of sickness in conifer trees.

Cracks and Splits

Big cracks or splits in the structure of the tree can be a sign that the tree is dead, especially if other warning signs are also present or if the crack is in the trunk.

Changing Bark

A strange or different bark texture can also spell trouble. Tree bark is often a good indicator of the tree’s overall health. If bark is missing, loose, dry, or brittle, be concerned. When branches lose their bark, it means those branches are most likely dead.

Infections and Infestations

Animals and fungi often start taking over dead trees too. Fungus usually only grows on decaying wood, so keep an eye out for mushrooms!

Insects like carpenter ants and beetles often set up camp in dead wood too. Look for rows of small holes in the wood or places where wood has clearly been eaten away:

Rotting Wood in the Trunk

A weak or spongy trunk can be a sign that a tree is rotting from the inside. If you notice this, call your local certified arborist right away. Rotting in the trunk is a sign that your tree may no longer be stable. You’ll want to get it taken care of before branches start falling, or worse, the whole tree comes down.

What Can I Do if My Tree Is Dead?

If your tree is dead, your best option is to have a professional come and remove it safely. If it’s a large or precariously positioned tree, you’ll want to do this as soon as possible.

If your tree is simply old, sick, or just unstable, you may have other options besides tree removal, such as cabling and bracing. Depending on the cause and extent of the damage, you might be able to salvage your tree or at least increase its life.

No matter what state your tree is in, an arborist, like us at Northwest Arbor Culture, can help you determine the best course of action for keeping your home safe and beautiful.

How To Plant a Tree

Friday, August 22nd, 2014

Planting trees is a fun and easy activity to do with your friends and family. When you plant trees on your property, you can add a lot of beauty and value to your landscape. While planting a tree can seem like a very simple task, there are many rules that you need to follow to ensure that your tree and landscape thrives.

Read this post to learn how to properly plant a tree so that it can grow and stay healthy for years to come.

Research and Placement

Always research the type of tree that you would like to plant before planting. Different species can grow to unwanted sizes, send out roots that damage concrete and landscaping, or drop leaves and needles that damage roofs and patios.

When choosing where to plant your new tree, there are several things to consider. First, make sure that your tree will not be placed too close to your home’s foundation or concrete structures. Generally, a space of 10 feet or more should be between any structure and your tree. Also, make sure to check with your State Utility Center to make sure that you won’t accidentally sever any dangerous electrical or water pipes on your property.

Consult your local nursery or arborist if you ever have questions about which type of tree to buy and where on your property to place it.

When To Plant

Different types of trees prefer to be planted throughout different seasons. Generally trees should be planted early or in the middle of spring or early to mid-fall. Avoid planting trees during the middle of summer because the heat and dryness can stress and kill a young tree.

Digging Your Hole

The depth and width of your hole is very important. If a tree is planted too deeply, the roots will have trouble absorbing oxygen and water through the top layers of soil. If a hole isn’t wide enough, the soil around the root ball will be too compacted to facilitate root growth.

Dig your hole at least 3-4 times as wide as the root ball of the tree. The depth of the hole should be slightly less than the height of the root ball. The ‘flare’ or collar of the tree where the base of the trunk begins to widen into the root structure should eventually sit just above the level of soil after the tree is fully planted.

Make sure not to compact the soil around the edges and bottom of your hole. Even using your shovel to loosen the surrounding dirt can assist the flow of water and root growth for your new tree.

Removing the Container

When you’re removing the tree from the container, be gentle but firm. Do not to pull the tree out by the trunk as this can hurt the entire root structure of the tree. Lay the tree on its side and tap and squeeze the container to loosen the soil. Gently slide the container off of the root ball of the tree. Cutting the container on both sides with a short blade (1-2 inches) can also help the removal process.

Separating the Roots

Depending upon how your tree was grown and how old it is, the roots may have formed to the shape of the burlap or plastic container. It is crucial that the roots of the young tree are not curling, twisted in circles, or bound around the tree. These types of roots will eventually expand and twist around themselves, essentially strangling or ‘girdling’ the roots of the tree and slowly killing it.

If the roots look ‘pot bound’ and twisted, use a short razor knife (1-2 inches) to make 4-6 cuts down the side and several cuts on the bottom of the root ball. This will cut and loosen twisted roots and force the tree to send out new roots in all directions helping it create an even and widespread root base.

Also, make sure to remove any stakes, ropes, and burlap from the tree before planting. These will inhibit root and tree growth.

Placing the Tree

Once the tree is prepared, place it in the center of your hole. Now is the time to align the branches and ‘pretty’ side of the tree to the main view point before you have fully planted it. Adjust the tree by the root ball, not by holding the trunk.

Make sure the top inch of the root ball is above the soil level and exposed. Place soil under the tree to slightly raise the level if needed. Once the root ball is in position use the soil you removed to fill in your hole. If your soil is mainly clay or particularly low-quality, you can use organic compost and other soil amenders to improve the quality. Avoid using heavy fertilizers and chemicals that can burn or kill a young tree.

After the hole is completely filled in, lightly tamp down the soil around the roots to stabilize the tree.

Creating a Berm and Mulching

Creating a water basin or berm around the base of your tree will fight soil erosion and hold water where the roots can absorb it. Make a 3 foot diameter circular berm about 3 inches tall around your tree. Make sure not to cover the trunk or flare of the tree.

Once you have created the berm, cover the entire planting area with 3-4 inches of mulch. Taking care to keep the mulch at least 2 inches from the trunk of the tree. Read our previous post for proper mulching techniques.

Watering

Finally you will want to water your newly planted tree. Give your tree about 5-10 gallons of water to begin with to help settle the soil and stimulate root growth. Water your tree daily for about two weeks and then every other day for about two months. Eventually you can water your tree once a week until it is completely established.

Now that you have successfully planted your tree, make sure to water, prune, and care for it properly throughout its entire life. Spending several hours a month caring for your tree will ensure that you have a healthy tree that will give add shade and beauty to your home.
