CHT Plant Propagation & Nursery Management 2

Question 1

In nursery management, what does 'liner' refer to?

Accepted Answer

Young, rooted plant ready for transplanting to a larger container

Answer

A liner is a small, young rooted plant (plug or rooted cutting) used as the starting material for growing on into a finished nursery product.

Question 2

Which container size is typically designated as a '5-gallon' in the US nursery trade?

Accepted Answer

A trade size container holding approximately 3.8 gallons

Answer

Nursery trade container sizes are nominal; a '5-gallon' container actually holds approximately 3.5–4 gallons of growing medium, not exactly 5 gallons.

Question 3

Soilless growing media used in container production is preferred because it:

Accepted Answer

Provides consistent drainage, aeration, and disease suppression

Answer

Soilless mixes (peat, bark, perlite) are lightweight, uniform, and resist compaction, providing consistent aeration and drainage critical in container production.

Question 4

What is the recommended practice when potting a container plant that is root-bound?

Accepted Answer

Score or tease the root ball before repotting

Answer

Scoring or teasing circling and matted roots before repotting encourages outward root growth and prevents girdling as the plant grows.

Question 5

Hardening off transplants involves:

Accepted Answer

Gradually acclimating greenhouse-grown plants to outdoor conditions

Answer

Hardening off gradually exposes greenhouse or indoor-grown transplants to outdoor light, temperature, and wind over 7–14 days to prevent transplant shock.
