The Best Tree Care Tip – Apply Wood Mulch


Applying organic wood mulch is the single best type of tree care.

If you do only one thing for your tree this year, apply wood mulch.


What is mulch and why is it good for tree care?

Any material placed on the soil to protect and cover it is classified as mulch. This can include stone, straw, shredded rubber, bark, pine needles, sawdust, and wood chips.

What is organic mulch?

Organic mulch can include shredded bark, wood chips, grass clippings, pine needles, dry straw, leaves, and other organically derived materials.  The opposite, inorganic mulch, consists of things such as crushed rock, stones, polyethylene, etc.  Organic mulch is preferred because the risk of soil pollution is eliminated and the material breaks down over time into substances that the tree can use.


Benefits of organic mulch

Organic mulch benefits tree health in many ways.  The most immediate benefit of mulch is soil moisture conservation.  A layer of mulch can reduce evaporation by as much as 73%[1]. Water is also absorbed and held by the mulch where it is slowly released into the soil below.

Soil erosion and water loss are greatly reduced due to the slowing down of the speed of rain and irrigation water by the mulch.  This allows the water to better infiltrate the soil and the mulch also conditions the soil to increase the infiltration rate leaving less water available to runoff.

Mulch reduces the competition of weeds for nutrients and water.  A layer of mulch 3″-4″ thick will very effectively prevent weeds from becoming established.  The lack of weeds can also decrease soil moisture loss as weeds increase evapotranspiration. This is especially helpful in the Fort Collins / Loveland area, or any other location with an arid climate, as we go through the annual hot & dry period for weeks at a time.

The fertility of the soil is increased by the presence of mulch.  As soil organisms break down the mulch through their activities nutrients are slowly released into the soil as nutrients that trees can take up through their roots.  This a better alternative to using chemical fertilizers as there is a much lower risk of these nutrients leaching into groundwater and causing pollution due to the rapid releasing of elements into the surrounding soil before the tree can uptake them.

Mulch improves soil structure by increasing the porosity of the soil.  Porosity is the presence of small pockets of open spaces in the soil.  These open spaces are filled with water and oxygen.  Both of which are critical for healthy root systems.  A soil with low porosity is far more difficult for trees to thrive in.

Soil temperatures are moderated by the layer of mulch making the soil cooler in the summer and warmer in the winter.  Soils with a moderate temperature and good aeration are ideal for root growth.  Healthy roots equal healthy trees.  Mulch can also prevent roots from freezing during extremely cold weather.

Some soil-borne disease can be reduced as well.  Water drops can splash disease spores from infected soil to healthy soil.  As discussed earlier, mulch reduces the splashing effects of water thereby reducing this risk.


How to apply mulch to trees

Mulch should be applied around the tree in a layer about 3″-4″ thick.  Begin near the trunk as spread it outward as far as you can.  It should be a minimum radius of 3 times the trunk diameter to be effective. 

For example, if the diameter of the trunk is 3″ then the wood mulch should be spread in a circle with a radius of at least 9″.  Make sure to avoid putting the mulch into direct contact with the trunk.  The tree trunk cannot handle having the mulch in direct contact as this creates a dark, moist environment perfect for insects and diseases to get established and damage the trunk. 

Mulch should be refreshed annually or even more frequently in hotter climates such as in Phoenix, AZ.


Tips for buying wood mulch

  • Compost mulch is better for tree nutrition than wood chips or bark as it is already partially broken down
  • Wood chips last longer, are less expensive and can be dyed in many colors
  • Avoid mulch with preservatives or fungicides added as this can be toxic to the tree and prevents nutrient breakdown
  • Colored mulches are ok as long as there are no strong preservatives in the coloring
  • A good source for FREE mulch is FreeWoodChips.net. The wood chips will be delivered by a local tree service.

5 Things You Can do to Lower the Cost of Tree Care

Here are 5 money saving tips for tree care:

  1. Keep your trees healthy by watering them properly and applying mulch.  Healthier trees will have lessSave money on tree care | Mountview Tree Experts dead branches that need to be pruned and will be stronger and more resistant to disease and insects lowering the cost of tree care in the future.
  2. Have your trees properly pruned when they are young to correct and prevent structural problems that will only increase in severity and cost more to correct as time goes on.  Have them inspected on an annual basis for the first 5-6 years.
  3. Have your mature trees pruned every 2-5 years.  Regularly maintained trees are better able to handle things like heavy snow storms and high winds.
  4. Get a bid from your trusted tree service for just the pruning if you have the means to dispose of the branches yourself.  This can save you 20%-40%.
  5. Schedule tree care during the winter months.  Most tree services slow down a bit during the winter and are willing to give a small discount to keep their crews busy.

Winter watering

Winter watering is important for optimum tree health

Don’t forget, your trees still need water even in the colder temps. If there has been less than 2″ of precipitation in the last thirty days it is time for supplemental water. One of the most effective ways to irrigate your trees is to put a garden hose in the root area and turn it on to a slow trickle and leave it for a couple hours. This allows the water to get deeper into the soil where more roots can come into contact with it.

The Value of a Tree

How much is a tree worth?

value of a tree

We already love trees but this is an interesting perspective.

It’s harder to take them for granted when you put a dollar value to them.  This is in addition to the aesthetic value trees bring to your property. The value of a tree may be more than we tend to think.

It reads:

“Of concern to all! A tree is worth $193,250. According to Professor T.M.Das of the University of Calcutta. A tree living for 50 years will generate $31,250 worth of oxygen, provide $62,000 worth of air pollution control, control soil erosion and increase soil fertility to the tune of $31,250. Recycle $37,500 worth of water and provide a home for animals worth $31,250. This figure does not include the value of fruits, lumber or beauty derived from trees. Just another sensible reason to take care of our forests.”

Snow load tips for Northern Colorado

Here are some tips to help your trees deal with the snow load:

  • Use a broom to brush or knock the snow off branches. Do not push down on the branches and be careful not to damage the bark. Evergreens are your first priority.
  • If possible, shaking the tree is more effective than using a broom on smaller trees.
  • Having your trees properly maintained and inspected by an Arborist can help to reduce the damaging effects of heavy snow.
