Class Code 0005
Nurseries – Propagation And Cultivation
Class Code 0005 covers nursery operations focused on propagation and cultivation of plants, including greenhouse and container production. California employers in this class should note the September 1, 2026 pure premium rate of $4.961 per $100 of payroll and understand how operations, safety, and payroll practices affect workers' comp costs.
What Class Code 0005 Covers
This classification applies to businesses whose primary activity is propagation and cultivation of plants: seed sowing, cuttings, grafting, transplanting, potting, soil mixing, bench and container production, and greenhouse environmental control. It includes both outdoor and controlled-environment (greenhouse) propagation activities and mechanized potting/bench operations. Routine tasks such as irrigation setup, fertilization, pest monitoring, and routine maintenance of propagation equipment are included. The class is focused on production labor rather than retail point-of-sale or landscape installation; operations that primarily sell plants at retail or perform landscape contracting may fall under different codes.
Who It Applies To
- Wholesale and production nurseries that grow plants for resale
- Greenhouse propagation and propagation-house staff
- Propagation technicians and production potting crews
- Irrigation and greenhouse environment technicians
- Nursery production supervisors and quality-control staff
Common Job Duties
- Sowing seed and rooting cuttings in trays, pots, or plugs
- Transplanting and repotting seedlings and container stock
- Mixing growing media and operating potting machines or conveyors
- Setting up and maintaining irrigation and misting systems
- Pruning, pinching, staking, and routine plant maintenance

Common Injury Risks
Understanding the $4.961 Rate
The WCIRB pure premium of $4.961 per $100 of payroll represents the portion of workers' compensation cost estimated to pay medical and indemnity claims for this classification. Insurers use the pure premium as the base; carriers then apply expense loadings, policy credits/debits, experience modification (loss history), class codes mix, and any deductible or retrospective rating adjustments to determine the actual premium an employer pays. Accurate payroll reporting, correct classification of operations, and proactive loss control all influence the final premium.
Cal/OSHA Compliance Requirements
Cal/OSHA requirements that commonly apply include heat illness prevention programs for outdoor and greenhouse workers, Hazard Communication for fertilizers and pesticides, and respiratory protection when workers may inhale dusts, mists, or fumigants. Employers must also follow machine guarding and powered industrial truck training standards, provide appropriate PPE, and comply with pesticide worker protection requirements administered by state and federal agencies.
How Key HR Helps Employers Under Class Code 0005
A PEO like Key HR can help nursery employers with accurate classification and payroll allocation, targeted Cal/OSHA-compliant safety programs, and on-site loss-control consultations to reduce exposures. Key HR also manages claims handling, negotiates medical and return-to-work plans, and consolidates purchasing and training resources to help lower experience modification and overall workers' comp costs.

Does Class Code 0005 include retail plant sales at a nursery storefront?
Code 0005 is focused on propagation and cultivation operations. Pure retail sales activity or a nursery that primarily sells at a customer-facing storefront may be assigned a different class code; if retail is incidental to production, payroll should be allocated between production and retail classifications.
What practical steps lower workers' comp costs for propagation crews?
Key steps include formal lifting and ergonomics training, mechanizing repetitive tasks (potting machines, conveyors), documented heat-illness prevention and hydration plans, mandatory PPE and tool maintenance, and establishing a light-duty return-to-work program to reduce indemnity costs and improve experience modification.
Are nursery employees who apply pesticides covered under the same rules?
Workers who handle or apply pesticides must follow the EPA Worker Protection Standard and California Department of Pesticide Regulation rules; some application tasks require certified applicators. Employers must provide specific training, decontamination facilities, and handling procedures in addition to Hazard Communication controls.
