Importance of Roots


Actual Root Spread

root radius (Gilman) = 2-4 X canopy radius

root area (Perry) = 4-7 X canopy area


Root Protection or Critical Root Zone Formulas

e.g. NADF, ISA - RPZ radius = 1 foot per 1 inch tree diameter @ DBH

USNA - RPZ radius = 1 foot per 1 inch tree circumference @ DBH




Specific – choose a plant which corresponds to your landscape need

e.g. shade or ornamental, screen or open


Site – match the biological needs of the plant with physical characteristics of site

e.g. acidic plants on alkaline soil, hydric on xeric sites


Space – ensure that enough space exists for future growth and vigor

e.g. palms under power lines, parking lot islands

Water your tree THOROUGHLY during DRY periods. Water is essential to tree survival and growth.

                    For a newly planted tree (i.e., 1-2 yrs): depending on season and weather conditions, water twice a week with 2 gallons/inch caliper over entire root zone.

                    For an established tree: water every 2 to 4 weeks with 1/2 to 1 inch over entire root zone.

Do not water indiscriminately! Always check soil before watering.



Mulch with woodchips or bark whenever and wherever possible

Mulch reduces: Mulch increases:

a) water loss a) organic matter

b) grass competition b) soil structure (tilth)

c) soil temperature c) water retention

Mulch should extend to cover the entire root zone (see PROTECTION).



Why? Source of nutrients removed

What? 3-1-1 ratio; 3 lbs. N per 1000 sq.ft. of root zone

How? Liquid organic soil injections are best; topical applications are sufficient.

When? Research varies. Fall probably best.

How often? As needed or every 3rd year





Prune according to THE TEN PRUNING COMMANDMENTS. Remember that they apply not only to the entire tree but to individual branches as well.


Young tree pruning - Structure!


Mature tree pruning - Little foliage as possible





Healthy plants survive pest infestations without significant harm!
