Basic Tree Care
  • Kris Thomas
  • City Of Dalton Certified Arborist ISA SO-5760A
a tree is the sum of it s parts

A Tree Is The Sum Of It’s Parts




Reproductive Organs

living systems die in three ways
Living Systems Die in Three Ways
  • Depletion of Energy(infection, starvation)
  • Dysfunction of parts and processes (genetics, toxins, poisons)
  • Mechanical disruption of parts & processes
take care to understand

Take Care To Understand

Take care to understand the world from a Tree’s perspective. They rely on us.

soil is made of three parts
Soil Is Made Of Three Parts
  • Gaseous – The Soil Air
  • Liquid – Percent Water
  • Solid – The Soil Minerals and Organic Matter
the soil air
The Soil Air
  • Pore space comprises 30 to 50 percent of soil volume. The quantity of air is governed by the amount of liquid in the pore space.Ordinarily air comprises 20 percent of the pore space in well tilled soil.
  • Oxygen and Nitrogen are two of the main components of soil air a tree needs for survival
roots and microorganisms respire
Roots And Microorganisms Respire
  • They continually take in O2 and emit CO2.
  • Poorly aereated soils restrict gas exchange and O2 supply decreases and CO2 supply increases.
  • City street trees with root areas between sidewalks and curbs face poor aeration and high CO2 levels
natural aeration provided by
Natural Aeration Provided By :
  • Cappillary and gravitational movement of water.
  • Changes in temperature and barometric pressure.
  • Addition of Organic Matter or Sand
  • Addition of Lime.
  • Channels left by decaying roots.
  • Earthworms.
trees that survive low aeration
Trees that Survive Low Aeration
  • Bald Cypress
  • Pond Cypress
  • Willows
  • River Birch
  • Sycamore
  • Hackberry
  • Swamp White Oak
  • Water Oak
trees that do not survive low aeration
Trees that Do Not Survive Low Aeration
  • Sugar Maple
  • Redbud
  • Yellowwood
  • Dogwood
  • Hawthorn
  • Colorado Spruce
  • Red Oak
  • Apple and Crabapple
poor aeration causes pests
Poor Aeration Causes Pests
  • Phythoptera cinnamomi or root rot is caused by the inability to drain the pore space of soil.
  • Causes shallow rooting.
  • Decreases the ability to absorb nutrients.A deficiency of Oxygen and excess CO2 reduce permeability of roots to water thus limiting mineral absorption
soil water
Soil Water
  • Water is an essential part of cell protoplasm
  • Exists in the soil in three states Hygroscopic, Capillary, and Free Water.
  • Hygroscopic a thin film of water covers soil particle, in equilibrium with air.
  • Cappillary- Water exists as heavier film attracted to the particle by it’s own surface tension.Stronger than gravitational pull.
  • Free Water- Is the water table. Deadly to roots.
influence of soil on nutrient availability
Influence of soil On Nutrient Availability
  • Sand, Silt, and Clay.
  • Organic matter
  • Cations + and Anions –
  • Cations : Hydrogen, Calcium, Magnesium,

Potassium, and Sodium.

Anions : Hydroxyl, Phosphate, Nitrate, Sulfate, and Chloride.

soil volume
Soil Volume
  • Ideally a tree needs 2 cubic feet of soil for each square foot of mature canopy.
  • To plan for a successful tree lifetime 60+ years we should provide at least 400 cubic feet of soil
  • In development stockpile the site soil and reuse.
structural soils and other solutions
Structural Soils and Other Solutions
  • Cornell Soil 60% limestone gravel 40% soil
  • Silva Cells
  • Lineal planting areas
  • Root Barriers
  • Root Trenches
other soil improvement methods
Other Soil Improvement Methods
  • Air Spading
  • Growth Regulators
  • Radial Trenching
  • Mulch
  • Compost

Three Forms Of Nursery Stock
  • Balled And Burlapped
  • Bareroot
  • Containerized
choose according to the site
Choose According To The Site
  • Arrangement of site to sunlight
  • Pollution
  • Utilities
  • Proximity to buildings
  • Traffic Patterns or Sidewalks
  • Soil Characteristics
  • Planting Space
  • Maintenance Requirements
why plant a tree
Why Plant A tree?
  • Provide Shade
  • Provide Aesthetics In The Landscape
  • Improve Air Quality
  • Reduce Storm Water Runoff And Improve Water Quality
  • Create Wildlife Habitat
  • Reduce Noise Levels
  • Provide Screening And Privacy
choosing the right tree for the right place
Choosing The Right TreeFor The Right Place
  • How tall will tree become in maturity?
  • What is the goal?
  • Ornamental or picturesque?
  • Maintenance
  • Root structure
  • Select Quality Trees
