In nursery management, what does 'liner' refer to?
Answer: Young, rooted plant ready for transplanting to a larger container
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.
Which container size is typically designated as a '5-gallon' in the US nursery trade?
Answer: A trade size container holding approximately 3.8 gallons
Nursery trade container sizes are nominal; a '5-gallon' container actually holds approximately 3.5–4 gallons of growing medium, not exactly 5 gallons.
Soilless growing media used in container production is preferred because it:
Answer: Provides consistent drainage, aeration, and disease suppression
Soilless mixes (peat, bark, perlite) are lightweight, uniform, and resist compaction, providing consistent aeration and drainage critical in container production.
What is the recommended practice when potting a container plant that is root-bound?
Answer: Score or tease the root ball before repotting
Scoring or teasing circling and matted roots before repotting encourages outward root growth and prevents girdling as the plant grows.
Hardening off transplants involves:
Answer: Gradually acclimating greenhouse-grown plants to outdoor conditions
Hardening off gradually exposes greenhouse or indoor-grown transplants to outdoor light, temperature, and wind over 7–14 days to prevent transplant shock.
Damping-off in seedling production is caused primarily by:
Answer: Soilborne fungi like Pythium and Rhizoctonia under wet, warm conditions
Damping-off is caused by Pythium, Rhizoctonia, or Fusarium fungi that attack seedlings at or below the soil line in overly wet, warm propagation environments.
