Identify trees and shrubs
This element focuses on building foundational skills for identifying common trees and shrubs used in UK horticulture, emphasising key morphological features such as leaf shape, bark texture, and overall form. Learners develop the ability to recognise species by both common and botanical names, supporting correct plant selection, care, and placement in practical horticultural settings. Mastery of these identification skills is essential for maintaining plant health, implementing design plans, and ensuring safe working practices in amenity and garden environments.
Assessment criteria
Topic Overview
The City & Guilds Level 1 Diploma in Practical Horticulture Skills is an introductory qualification designed for students who want to start a career in horticulture or land management. It covers the fundamental practical skills needed to work safely and effectively in gardens, parks, nurseries, and other green spaces. Topics include plant identification, soil preparation, planting techniques, pruning, and the use of hand tools and equipment. This diploma provides a solid foundation for further study, such as the Level 2 Diploma in Horticulture, or for entry-level roles like gardener or grounds maintenance operative.
Horticulture is a vital industry in the UK, contributing to food production, environmental conservation, and public wellbeing. This course emphasises hands-on learning, so you will spend much of your time outdoors developing practical competence. You will learn how to select and use tools correctly, maintain a safe working environment, and apply basic horticultural principles to real-world tasks. By the end of the diploma, you will be able to carry out routine horticultural operations under supervision, making you a valuable asset to any landscaping or gardening team.
The qualification is structured around mandatory units covering health and safety, plant growth, soil management, and practical maintenance. Optional units allow you to specialise in areas like turf care, pruning, or using machinery. Assessment is through practical observations and written tasks, so you need to demonstrate both skill and understanding. This diploma is ideal if you enjoy working outdoors, have an interest in plants, and want a clear pathway into a rewarding career.
Key Concepts
Core ideas you must understand for this topic
- →Plant identification: Learn to recognise common UK plants, including trees, shrubs, herbaceous perennials, and annuals, using features like leaf shape, flower colour, and growth habit.
- →Soil preparation: Understand soil types (clay, sand, loam) and how to improve them with organic matter, drainage, and pH adjustment for optimal plant growth.
- →Safe tool use: Master the correct handling, maintenance, and storage of hand tools like secateurs, spades, and rakes to prevent accidents and prolong tool life.
- →Planting techniques: Know how to plant container-grown and bare-root plants at the correct depth, with proper spacing and aftercare (watering, mulching).
- →Pruning basics: Learn the principles of pruning to remove dead or diseased wood, shape plants, and encourage healthy growth, using clean, sharp tools.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurate identification of a minimum of 10 tree and shrub species using common names and correct botanical epithets.
- Marks should be given for correctly describing distinguishing seasonal features (e.g., deciduous vs. evergreen foliage, winter bud arrangement).
- Credit evidence that demonstrates use of a plant key or identification guide, showing logical steps taken to confirm species.
- Award credit for clear annotation of photographs or samples, highlighting diagnostic characteristics such as leaf margin, venation, or bark pattern.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference at least two features (e.g., leaf arrangement AND bark texture) to solidify identification before recording a final answer.
- 💡For practical assessments, create a photographic plant portfolio with labels noting key ID points; this demonstrates ongoing competence and can be used as portfolio evidence.
- 💡Learn the botanical naming conventions (genus + species) as a minimum; this shows professional standard and avoids ambiguity in written assessments.
- 💡Always wear appropriate PPE (gloves, safety boots, eye protection) during practical assessments – it shows you take health and safety seriously and can earn you marks.
- 💡When identifying plants, use a systematic approach: look at leaf arrangement, shape, and margin; then check flower structure if present. Practice with common species like daisy, rose, and oak.
- 💡In written tasks, use correct horticultural terminology (e.g., 'deciduous', 'perennial', 'loam') and explain the 'why' behind your actions – this demonstrates deeper understanding.
Common Mistakes
Common errors to avoid in your coursework
- Confusing species with similar leaf shapes, such as Acer campestre (field maple) and Platanus × acerifolia (London plane), leading to incorrect care practices.
- Relying solely on flower or fruit for identification, which may not be present year-round, causing misidentification in non-flowering seasons.
- Using only common names, which can vary regionally (e.g., ‘may blossom’ for both Crataegus monogyna and Prunus padus), resulting in ambiguity in professional communication.
- Overlooking juvenile foliage differences, as seen in some Eucalyptus species, where young leaves differ markedly from mature leaves.
- Misconception: 'All plants need the same amount of water.' Correction: Water requirements vary greatly; overwatering can cause root rot, while underwatering stresses plants. Always check soil moisture before watering.
- Misconception: 'Pruning is only for shaping plants.' Correction: Pruning also removes diseased or damaged growth, improves air circulation, and stimulates fruit or flower production. Timing is crucial – prune at the right season for each species.
- Misconception: 'Fertiliser is always needed for healthy plants.' Correction: Many plants thrive in well-prepared soil without extra fertiliser. Over-fertilising can burn roots and harm the environment. Test soil first and only add nutrients if deficient.
