Objectives

The primary objective is to appoint a service provider for a three-year period to deliver comprehensive turf grass and lawn maintenance at the Pretoria National Botanical Gardens. The project aims to enhance the facility’s structural functionality, safety, and environmental conditions while ensuring the lawn remains green, healthy, and free of visible weeds, pests, and diseases. All maintenance activities must be executed with minimal disruption to garden visitors and institutional operations.

Scope of Work

The contractor will manage approximately 4.25 hectares of varied lawn types across the botanical garden. Core responsibilities include:

• Pest and Disease Control: Routine inspections, application of environmentally compliant pesticides and fungicides, and implementation of preventive protocols.
• Weed Management: Manual and chemical removal using selective herbicides, supplemented by preventive strategies such as targeted fertilization and overseeding.
• Soil and Fertilization Management: Annual soil testing, development of nutrient-specific fertilization schedules, and periodic aeration to alleviate compaction.
• Lawn Restoration: Sod installation, species-appropriate overseeding, and erosion control measures in vulnerable zones.
• Operational Coordination: Scheduling work in consultation with garden personnel to optimize access and minimize visitor impact, alongside strict compliance with occupational health and safety legislation.
