Micronutrients and the need to fertilize.

High Pressure Soil Injected Fertilization

Proper fertilization is vital to the health of trees. This is especially true here in the Valley of the Sun. We not only have a hot, harsh climate but we also have an acidic soil to contend with.

One of the best method for feeding trees is to have the fertilizer already bound to a water molecule before it is presented to the roots. We do this by pre-mixing the fertilizer in a tank and injecting it into the ground at high pressure. Our probe is designed to shoot the fertilizer both sideways and downward evenly, spreading out the micro nutrients and aerating the roots in the process.

Feeder Roots A few years ago, scientists discovered the specialized roots that pick up micro nutrients. They were surprised to learn that over 90% of these specialized roots were only 8 to 10 inches deep, and that they grew upward.

Don’t be fooled into having someone talk you in to 'deep root feeding' your trees. It is a waste of money because most of the roots that can actually process the fertilizer are shallow.

Mycorrhizae The first time we fertilize someone’s trees we also inject mycorrhizal fungal spores into the soil. This turns your roots into super roots and the mycorrhizal fungus becomes a permanent part of your tree's root system. This friendly fungi acts as a barrier to the bad fungus that lives in most Arizona soil.

Plants with Specal Needs Some plants, like queen palms, have specal needs. Queen palms evolved in a place where only a limited number of micro nutrients were available. In order for queen plams to stay healthy, they require a lot of manganese and manganise is not present in our native soil. This is why the queen palms do so poorly here when confronted with a fungal attack.

At Warner's Tree Surgery we are well versed in the particular needs of plants and in soil science, you can count on us to use our knowledge to do a good job.

The Roots

Here’s a list of top ten root facts I compiled a few years back. My apologies to David Click to enlarge.letterman.

  1. Tree roots must have oxygen, water, and nutrients to function. Either excessive precipitation or drought can damage root systems.
  2. The feeder roots can extend two to four times beyond the branches.
  3. Most of the absorbing roots are in the top few inches of soil and grow upward toward the surface, not downward.
  4. Compaction of soil and covering roots with soil, paving, or water deprives roots of oxygen and is deadly to trees.
  5. Removing soil from the root zone of trees kills the nearly invisible root hairs. Trenching or grading severs tree roots.
  6. High root zone temperatures can develop from surrounding pavement, thus impairing the vigor of the tree.
  7. Grass growing in the root zone of trees can inhibit fine root development by as much as 90 percent compared to a natural environment.
  8. Root systems of urban trees are typically a fraction of their forest counterparts' because of space and soil limitations.
  9. Urban soils are often unsuitable for vigorous tree-root growth.
  10. Planting and maintenance procedures can "make or break" a tree's root system.

This link will bring up a page that graphically shows a tree as a system, please take a minute and look at it. This is the best graphical representation of a tree as a system I havA tree as a systeme seen. I apologize for the poor quality but I copied it a few years back and I have been unable to find a clearer picture on the internet. If anyone can give me a link to a better copy I would appreciate it. My email address is warnerworking@yahoo.com, thanks.
