CATS CATS - Certified Arborist Tree Service of Albuquerque Tree Planting and Establishment Questions and Answers 2

Question 1

At what depth should a balled-and-burlapped tree be planted according to best arboricultural practice?

Accepted Answer

With the root flare at or slightly above existing soil grade

Answer

Burying the root flare causes bark decay, girdling roots, and decline; keeping it at or above grade ensures oxygen reaches the crown roots.

Question 2

Why is it recommended to remove wire baskets and burlap from rootballs during planting?

Accepted Answer

They restrict root expansion and can girdle developing roots

Answer

Non-degraded wire and burlap can girdle roots and restrict outward growth for years, ultimately weakening tree structure.

Question 3

What is the recommended planting hole width according to ISA and ANSI planting standards?

Accepted Answer

Two to three times the diameter of the rootball

Answer

A wide, shallow hole loosens surrounding soil so new roots can extend easily into the backfill and native soil.

Question 4

Which mulching practice best supports newly planted tree establishment in Albuquerque's dry climate?

Accepted Answer

A 3-4 inch deep mulch ring to the drip line, kept away from the trunk

Answer

Proper mulch depth conserves soil moisture, moderates temperature, and suppresses weeds without promoting trunk decay.

Question 5

When is staking of a newly planted tree actually recommended?

Accepted Answer

Only when the tree cannot stand upright on its own or is on a high-wind site

Answer

Unnecessary staking prevents trunk taper development and can cause girdling if stakes and ties are left too long.
