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

How often should a newly planted tree be deeply irrigated during Albuquerque's hot summer months?

Answer: Every 7-14 days with deep slow irrigation to encourage deep root growth

Deep, infrequent irrigation encourages roots to grow downward toward stable soil moisture rather than remaining near the surface.

What is the general establishment period for a 2-inch caliper tree planted in New Mexico's climate?

Answer: Approximately one year per inch of trunk diameter

Larger transplants have more root mass to regenerate, and New Mexico's heat and low humidity slow recovery compared to milder climates.

Which post-planting treatment is NOT recommended for newly planted trees?

Answer: Heavy fertilization immediately after planting

Fertilizing stressed transplants stimulates top growth before the root system can support it, increasing drought stress and dieback risk.

What is the purpose of constructing a watering berm around a newly planted tree?

Answer: To direct and concentrate irrigation water to the root zone

A berm creates a temporary basin that allows water to soak slowly into the root zone rather than running off the surface.

When should structural pruning of a newly planted tree be performed?

Answer: Defer structural pruning; only remove dead, damaged, or crossing branches at planting

Removing foliage reduces the photosynthetic capacity needed for root regeneration; only defective wood should be removed at planting.

Which symptom indicates a newly planted tree in Albuquerque is experiencing transplant shock?

Answer: Wilting, leaf scorch, or premature leaf drop despite adequate irrigation

Transplant shock reflects the tree's inability to absorb enough water due to root loss, even when soil moisture is adequate.
