Undertake Identification, Selection and Use of Ornamental Plants — City & Guilds Limited Occupational Qualification Horticulture & Land Management Revision

Topic Synopsis
This element focuses on the comprehensive process of identifying ornamental plants accurately, selecting appropriate species based on environmental and aesthetic factors, and preparing professional planting designs. Practical application includes integrating plant knowledge into landscape schemes, ensuring correct planting techniques for trees and shrubs, and implementing effective aftercare to establish and sustain healthy plantings.
Key Concepts & Core Principles
- Plant taxonomy and identification: understanding botanical names, plant families, and key characteristics for accurate identification.
- Soil science: analysing soil texture, structure, pH, and nutrient content to optimise growing conditions.
- Integrated pest management (IPM): using biological, cultural, and chemical controls to manage pests and diseases sustainably.
- Plant propagation: techniques including seed sowing, cuttings, grafting, and division for producing new plants.
- Landscape design principles: applying elements like balance, proportion, and unity to create functional and aesthetic outdoor spaces.
Exam Tips & Revision Strategies
- Always use scientific Latin names for plant identification in assessments to demonstrate professional competence.
- Reference industry codes of practice (e.g., BS 8545 for tree planting) and current horticultural guidelines when justifying selection and methods.
- Include a clear, logical structure in planting designs, linking design choices back to site analysis findings and client brief.
- In aftercare plans, specify measurable actions (e.g., 'water twice weekly for first season') and cite potential pest/disease issues with integrated management strategies.
Common Misconceptions & Mistakes to Avoid
- Relying on common names rather than binomial nomenclature, leading to confusion in plant orders and specifications.
- Selecting plants based solely on appearance without considering mature size, root spread, or long-term maintenance requirements.
- Neglecting soil assessment and amendment, resulting in poor establishment and plant failure.
- Planting trees and shrubs too deeply or failing to remove container root spirals, causing girdling and decline.
- Providing generic aftercare advice without tailored schedules for specific plant groups, leading to over- or under-watering and neglect of formative pruning.
Examiner Marking Points
- Award credit for demonstrating accurate identification of a range of ornamental plants using correct botanical nomenclature (genus, species, cultivar).
- Provide evidence of detailed site analysis and plant selection criteria, matching plant characteristics (hardiness, soil pH, light requirements) to specific site conditions.
- Produce a scaled, annotated planting design with a plant key, quantities, and specification notes, ensuring compliance with industry standards for tree and shrub placement.
- Demonstrate correct planting procedures for trees and shrubs, including root preparation, planting depth, staking, and initial watering, with reference to best practice guidelines.
- Detail a comprehensive aftercare plan covering watering regimes, mulching, formative pruning, pest and disease monitoring, and seasonal maintenance schedules.
