Plant Health Care (PHC)

What is PHC?

Symptoms, such as discolored leaves, dead branches, or early leaf drop, can be a signs of plant health issues and a cause for concern in your landscape.


Frequently, the causes of these concerns are minor abiotic problems that can be easily explained and corrected. Other times, the problems are more complex with several underlying causes. The remedies for these more complex issues can sometimes require treatment regimens with specific functions and or targeted control measures. Some of these regimens may extend over several years.

Our Goal

The goal of a PHC program is to be aware of and familiar with all of the aspects of your landscape, in order to prevent serous problems from occurring. PHC involves monitoring your landscape with these things in mind:

  • Appearance
  • Vitality
  • Safety
  • Cost Effective Treatments
  • Environmentally Responsible Practices

Some of our most effective PHC practices include:

  • Root Collar Maintenance
  • Deep Root Fertilization
  • Core Aeration
  • Pruning
  • Preventative/Curative Insecticidal Treatments
  • Anti-desiccant Application
  • Mycorrhizae Treatment
  • Soil Samples
  • Cultural Corrections
  • Moisture Management applications

Deep Root Fertilization

Mother-nature has been taking care of trees for longer than we have been. In order to better maintain turf, we rake up the leaves and sticks from our yards and haul them away. Every year we lose some nutrients from our yards just by doing the regular maintenance needed to keep our yards beautiful. Due to nutrient loss and human activities, the soils in the urban environment tend to be less than ideal for healthy tree growth. We often need to put some of these missing nutrients back into the soil.

An easy way to do this is to follow a deep root fertilization program. Deep root fertilization provides a way to get the necessary nutrients below the turf roots where the tree roots have access to them without much competition. If trees do not have the proper nutrients, or they are growing in a soil with the wrong pH, they can be more susceptible to certain diseases and insect pests. Appropriate fertilization can increase growth and vitality of our trees and help them weather the barrage of stresses they face every year.

All of our fertilization applications are done in compliance with ANSI A300 Standards for fertilization.

Specialized Plant Health Care Services

Root Pruning: Just like the various types of crown (the above ground portion of the tree) pruning we offer, we can prune the roots of trees as well. If your tree has malformed roots or roots growing where they shouldn’t, the staff at our sister company, Meyer Tree Service, can excavate around the tree and prune roots quickly and professionally.

Soil De-Compaction: One of the big challenges tree roots face in our area is trying to grow through compacted soil. We have the ability to ‘fluff’ the soil around trees without damaging the roots. We can also amend the soil with organic material at this time. This will help the soil to retain water and create a better soil structure for the roots to grow in.

Tree Injections: One of the jobs of roots is to absorb nutrients for the tree. Some soil conditions prohibit the uptake of nutrients. In this case, we can directly inject supplemental nutrients into the tree using a proven minimally invasive process.

Construction Consultation: The best way to fix construction damage is to prevent it. We can work with you and your construction company to save trees before, during, after the construction process.
