planting course study

Bare root

Tree removed for transplanting without soil around roots

Container-grown

Tree grown entirely in a container

Containerized

Field-grown plant later placed into a container

Balled and burlapped (B&B)

Tree removed with roots and soil wrapped in burlap

Root ball

Mass of roots and soil moved during transplanting

Trunk flare

Base of trunk where it widens into structural roots

Planting hole

Hole dug for planting; wider than root ball, not deeper than root flare

Backfill

Soil placed back around the root ball after planting

Native soil

Original site soil used for backfilling

Burlap

Natural wrapping around B&B root ball; may be cut away

Synthetic burlap

Artificial wrapping that must be removed to prevent root restriction

Wire basket

Metal basket supporting a B&B root ball

Root pruning

Cutting roots to promote dense root growth before transplanting

Mechanical tree spade

Machine used to dig and move trees

Drum lace

Method of tying root ball for transport

Glazed sides

Compacted smooth sides of planting hole restricting root penetration

Interface

Boundary between two different soil textures

Perched water table

Water accumulation above a less permeable soil layer

Teacup effect

Water collects in planting hole due to poor drainage differences

Root flare excavation

Removing excess soil/mulch to expose trunk flare

Sweating

Pre-planting treatment for bare-root trees to break dormancy

Circling roots

Roots growing in circular pattern around root ball

Girdling roots

Roots wrapping around trunk restricting flow of water and nutrients

Adventitious root initiation zone

Palm base area where new roots form after transplant

Palm transplanting

Moving palms; they tolerate transplanting due to root regeneration

Terminal bud protection

Protecting palm’s single growing point during transplant

Desiccation

Severe drying out of plant tissue

Hardened off

Plant acclimated to new environmental conditions

Sunscald

Bark injury from rapid temperature changes

Antitranspirants

Substances applied to reduce water loss from foliage

Vigor

Plant’s inherent ability to grow and resist stress
