Month: January 2015

As Portland certified arborists, we start looking for signs of spring after the winter holidays have passed. Even in January, smack

dab in the middle of winter, you can find clues that spring is on its way. Buds on many deciduous plants are swelling, storing energy for upcoming blossoms. Witch hazel is blooming, as are some plum trees. And dry days allow gardeners to get outside and plan for the approaching growing season. January is also the perfect time to check for tree damage. Read on to learn tasks Portland homeowners can do to keep their trees healthy this month.

In January, the lack of leaves facilitates tree checkups. Checking the health of your trees during the winter is extremely important. To assess tree health, choose a dry day to walk around and examine trees from every angle. Winter conditions can lead to tree damage. Frost cracking damage can occur on the trees’ southwest side, where winter sunlight causes wide temperature swings. Early winter frosts can kill autumn growth; frost ice crystals burst cell walls at the tips of branches. Dry, cold conditions can cause winter drought, in which the tree cannot pull enough moisture from the frozen ground. Rodents desperate for food at this time of year may chew on bark or cones. And of course, branches may break in high winds, ice storms, and snow. Protecting your fruit trees is also important. Winter tree spraying in Portland is a great way to protect your fruit trees from being vulnerable to insects and diseases.

How to Protect Trees From Winter

Here’s how homeowners can protect their trees in winter, they can start with having a tree assessment done by an Urban Forest certified arborist. Also, homeowners can conduct a preliminary appraisal of tree health by walking their properties and checking for:

1. Consistent Bark texture and coloration. Bumps, growths, dark spots, sap trails, and white or yellow tinges can all signify tree sickness. Peeling bark may indicate an underlying dead layer of tissue, and is a sign that you should contact a certified arborist for assistance.
2. Decay fungus. Have you noticed circular fungi growing outward on your trees? This formation is called a conch; it is a woody mushroom that signifies that there is decay inside the tree. You may also find decay fungi growing on the ground immediately below a tree. In either case, call us. Our arborists can track down the decay and suggest appropriate responses.
3. Strong Joints. A tree joint is the place where a branch meets the trunk. Keep an eye out for cracks in the joints; weakness in joints often precipitates falling limbs. This is especially key for multiple-stem trees with more than one leader. A narrow angle of connection between adjacent branches, with a crack extending below the joint, is especially indicative of a weak joint. It’s better to take care of any joint weaknesses early, so that you still have the option to thin the tree or add a support cable (rather than cut the whole tree down because it is so unstable and likely to fall in a storm).
4. Sprouts. If a tree is in distress, it will often put out new sprouts at the trunk base, or from wounds. An arborist should be called in to detect what is stressing a sprouting tree.
5. Cracks and Splits anywhere in a tree suggest weakness. Moreover, these indentations allow moisture into the tree, which can eventually lead to rot.
6. Dead branches, which could come crashing down in high winds and otherwise stormy conditions.

Once your assessment is done, consider adding mulch as protection. Create a ring of wood chips, at a depth of 2-4 inches, extending in a two foot radius away from the base of the tree, leaving a slight mulch-free gap around the trunk. Mulch helps prevent soil compaction and root suffocation.

We do not recommend that homeowners attempt to prune trees at this time of year. While we understand your desire to clean up after storms, improper pruning can cause significant damage. As Paul Ries, Oregon Department of Forestry urban forester explains, “It’s often the case that more trees become damaged as a result of improper post-storm activities, than were damaged directly by a storm.” Correct pruning can improve tree health; incorrect pruning breeds tree disease. Contact a professional for any pruning concerns you may have. As trees are dormant in the winter month, pruning can be accomplished effectively, and with minimal damage to surrounding plants (which are also dormant).

January is also part of planting season, although most gardeners will be spending this time planning for the spring. Before tree planting, Portland residents should:

• Consider space availability. Ensure enough room for the mature tree’s crown and root system.
• Check for overhead hazards, such as utility lines. Also double check that the tree won’t be growing downward into underground obstructions.
• Note surrounding soil conditions. Different tree species will prefer sandy, clay-heavy, or well-drained soils.
• Think about Water Availability. Will there be enough water to keep the tree healthy? Think about how you will water the tree if the spot you’ve chosen doesn’t stay moist naturally.
• Select Species According to your Goals. What functions should the tree provide? Are you looking for shade, wind protection, or an enchanting scent? Your preferences will be the main factors in tree selection.

When to Do It & What to Do With Extra Fruit

In this article we discuss why December and January are the ideal months for fruit tree pruning. Read on for fruit tree-pruning tips, including whom to contact for tree pruning services. We also discuss a common conundrum for fruit tree owners: What to do with extra fruit.

Why Prune Fruit Trees in the Winter? Annual pruning is important for all fruit trees. Winter is the best season for pruning fruit trees, because this is when they are dormant. During the cold months, the plant is in an inactive state, storing up energy for the following growth cycle. Energy gathered from summer sunlight is stored in the tree’s roots. At the end of the branches, new buds are starting to form for the next growth and fruiting cycle. Winter is well suited for training branches to grow into the shape of your choice; removing water sprouts (branches growing straight up); and eliminating crossed branches.

DIY Fruit Tree Pruning Tips. You may have heard that tree trimming is best left to professionals. This is generally true, but as Portland tree pruning experts, we consider fruit tree pruning accessible for most homeowners.

Safety First. Of course, you should always prioritize safety first when pruning. Working at height is rife with fall hazards. Assuming you’re following safety precautions, it’s empowering to learn how to properly prune and train your fruit trees.

Here are some useful fruit tree pruning tips for those in the DIY crowd:

1. Use the Right Tools. Of course, pruning requires a set of decent pruning shears, as well as a sharpening stone to keep the blade sharp. You may also want a quality pair of two-handed loppers (AKA brush cutters), and a pruning saw. Expect to pay between $100 and $250 in total for these three items. Additionally, you might need to purchase a pruning ladder to access upper branches.
2. Understand the Basics of Pruning. Hormones dictate plant growth, so understanding the flow and cycle of these hormones is paramount to understanding how your cuts will affect plant growth down the road. With experience, you’ll get a feel for the art and science of pruning, as you anticipate how the tree reacts to your cuts. This is the expertise that our certified arborists have spent decades honing. The basics, for beginners to keep in mind, follow.

You’ll definitely want to prune away diseased and dying branches. Crossed limbs should also be removed. Next, cut away water sprouts and suckers, which grow near the base of the trunk, from the roots, or at the top of the tree. Finally, imagine throwing a cat through the tree. It may sound crazy, but this visual is a good rule of thumb to remember how much to prune away. You can also visualize where you want the tree to look like in five years, and remove branches that don’t fit that vision. Such pruning will help to open the center of the tree to improve air circulation and sunlight absorption.

Proper Portland tree pruning is all about cutting into the branch in a purposeful way. Avoid cutting into the branch collar, a swollen, wrinkled area that forms where the branch and trunk meet. This is where the tree heals from a cut. To prevent heavy branches from breaking (and inviting disease) use three cuts: 
a) Place the blade about an inch above the branch collar on the underside of the branch you wish to remove.
b) Cut all the way across the branch, cutting from the topside of the branch down, with the blade just beyond the first cut you made.
c) Finally, cut away the nub, slicing off the section remaining above the branch collar.

3. Know your limits. Even with a good pruning ladder (the three-legged variety), pruning at the top of the ladder can be scary, risky, and downright dangerous. Don’t exceed your limits. If the situation feels unsafe, than it’s probably best to call a licensed and bonded professional who carries their own insurance.

What to do with Extra Fruit. Excess fruit can be a hassle to deal with. If you simply cannot use or harvest all the fruit your tree produces, there is a solution: the Portland Fruit Tree Project. This inspirational non-profit group registers Portland nut and fruit trees, harvests their crops, and distributes the proceeds to those in need. We are happy to help the Portland Fruit Tree Project harvest thousands of pounds of fruits and nuts per year. The Portland Fruit Tree Project also hosts hands-on workshops to teach homeowners about tree care and preservation.
