Tips to Keep Mature Trees Healthy

Tips to Keep Mature Trees Healthy

Our urban forest (yes, the trees in your landscape are part of a forest) provides so many benefits too us – cooling, increased home values, beauty, and better mental health just to name a few.

Here’s what you can do to help keep your members of our urban forest as healthy as possible.

1. Water your trees to a depth of about two feet, because 95% of the tree’s roots are in the first two feet of soil.  To check if you are getting down to that two-foot optimum, insert a long screwdriver or soil probe into the soil around your tree a day after watering to determine the depth the water has reached.  Adjust your watering time, if needed, to reach that two-foot goal.

2. Water your trees a little inside and outside of the canopy edge (the outer ring of the tree’s leaves) because that is where the roots that take in water are located. 

3. Water deeply and infrequently for maximum tree health.  See the Summer Watering Recommendations for more information.

4. Check your trees for signs that they aren’t getting enough water: wilted leaves early in the morning, scorched leaf edges, twig die-back from the top down or a sparse leaf canopy. 

5. Take advantage of rainwater by directing downspouts or canales toward existing trees. Consider planting new trees in lower areas to take advantage of captured moisture.

6. Surround your trees with 4-6 inches of organic mulch. Organic mulch helps to retain soil moisture, keeps soil temperatures more consistent, and keeps weeds out. Additionally, over time it loosens compacted soil, adds organic matter, and slowly adds nutrients to the soil. Note: organic mulch does not include bark (sometimes called ‘bark nuggets’ or ‘deco bark”). Use actual wood chips like what comes out of an arborist’s woodchipper.  Many tree services offer wood chips for free and several local businesses sell wood chip mulches in bulk.

February 2020 Monthly Service Tip and Watering Recommendations

February 2020 Monthly Service Tip and Watering Recommendations

Watering Recommendations:

When warmer days set in, you may be inclined to water your landscape, but this winter continues to bring much needed precipitation to meet the needs of your landscape. No need to water this month!

Per our Winter Watering Recommendations, your yard is still getting enough water to meet your plant’s needs. Remember, if it rains more than a half inch or snows more than 6 inches at least once per month during winter season, there’s no need for supplemental irrigation.

Monthly Service Tip:

Late winter is the best time to prune trees, Treebates available. They’re dormant and it’s easier to identify which branches need trimming (no leaves). Tree pruning cuts don’t heal like cuts on our skin, though. Tree cuts seal naturally both internally and externally, as long as the cut is well made and doesn’t nick the branch collar. Cuts made flush against the trunk are bad because they cut into the branch collar, making the plant unable to seal the wound on its own. Pruning sealants are no longer recommended because they keep the wound moist underneath and increase the chances of rot by trapping pathogens there.

Recommended pruning techniques continue to change with new research. Keeping up with the newest guidelines translates to better tree care. The late Dr. Al Shigo, biologist and plant pathologist with the U.S. Forest Service, once said, “People who prune the old-fashioned way should be made to go to an old-fashioned dentist.”

Using the right tools for pruning is key. How do you know if you’re using the wrong tool? If you’re using two hands to squeeze your pruning shears as hard as you can, or your thigh to brace one arm of long-handled loppers, you’re using the wrong tool! Move up to a larger size implement. Here’s a literal rule of thumb: if the branch diameter is the size of your thumb or smaller, hand pruners with a sharp blade will work. Lopping pruners are great for making cuts on branches up to 2 inches in diameter. For anything larger than 2 inches, it’s time to pull out the pruning saw.

Help, my trees need pruning!

Help, my trees need pruning!

The winter is best time of  year to prune trees. The Water Authority recommends hiring an arborist to prune them because arborists specialize in the care of individual trees. They are knowledgeable about the needs of trees and are trained and equipped to provide the proper care.

Arborists can provide the following services:

  1. Pruning
  2. Tree removal
  3. Emergency tree care
  4. Planting
  5. Plant health care
  6. Other services such as consulting, tree risk assessment, cabling and bracing of trees.

How do you find a professional arborist to take care of your trees? We recommend to ask the following questions when looking for an arborist:

  1. Are they certified? Certified arborists have achieved a level of knowledge in the art and science of tree care through experience. They have  passed a comprehensive examination developed by some of the nation’s leading tree care experts. There is an online resource called Find an Arborist to help you locate one in your area.
  2. Do they have insurance? Check that they have a certificate of insurance that includes proof of liability for personal and property damage, including workers’ compensation.
  3. Do they offer a contract? Get a written contract of the work to be completed from the arborist. It should include the estimate for the services, a start date, and estimate of how long the work will take.
  4. Do they have references? Ask the tree company to provide a few names of past customers, and ask friends and neighbors for local references, too.
