Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct root ball preparation, including size assessment (minimum three times the stem diameter for trees) and the use of hessian/wire cages to maintain integrity during lifting.
- Provide evidence of selecting and operating appropriate lifting and transport machinery (e.g., tree spades, HIABs) with reference to load security, stability, and route planning to avoid overhead hazards.
- Show competence in site preparation: testing soil drainage, digging a planting pit twice the width of the root ball but no deeper, and incorporating organic matter only if soil conditions are poor.
- Demonstrate correct planting technique: removing all wrapping materials from the upper portion of the root ball, positioning the root collar at or slightly above grade, backfilling with native soil, and firming gently to eliminate air pockets.
- Include evidence of thorough aftercare: installing tree stakes or guying systems at the time of planting to prevent root disturbance, applying a 5–10 cm organic mulch layer (avoiding contact with the stem), and implementing a regular watering regimen adjusted for seasonal conditions.
- Maintain and present inspection records for all equipment used, including daily checks of spades, lifting straps, and machinery in line with PUWER requirements, with any defects and corrective actions logged.
- Demonstrate adherence to health and safety legislation by conducting a site-specific risk assessment before operations, identifying hazards such as underground services, overhead cables, and traffic, and implementing control measures. Show evidence of environmental good practice through responsible disposal of wrapping materials and waste soil.
Assessment Guidance
Guidance for achieving higher grades
- 💡For written assignments, always link practical actions to plant physiology—explain why minimising root disturbance reduces transplant shock (e.g., preserving mycorrhizal associations and fine root hairs).
- 💡When describing equipment maintenance, reference specific legislation (e.g., PUWER 1998, LOLER if applicable) and typical inspection intervals (daily, weekly) to show compliance knowledge.
- 💡In practical assessments, verbalise your decision-making: state why you have chosen a particular staking method based on site exposure, soil type, and plant size.
- 💡For health and safety elements, use real-world examples in your evidence—include a sample risk assessment and a method statement tailored to a typical transplanting scenario.
- 💡Always use correct scientific terminology, such as 'photosynthesis' and 'transpiration', to show depth of knowledge.
- 💡In practical assessments, demonstrate safe working practices and correct tool use; this is often part of the marking criteria.
- 💡When answering questions about plant care, consider the specific conditions of the site, such as light, soil, and climate, and mention them in your answer.
Common Mistakes
Common errors to avoid in your coursework
- Planting too deep: setting the root collar below the soil surface, which can lead to stem rot and reduced oxygen supply to roots.
- Neglecting to remove or adequately loosen transport wrapping, causing root binding or girdling as the plant attempts to expand.
- Over-staking or failing to remove stakes after the first growing season, preventing the development of natural trunk taper and anchorage.
- Applying excessive fertilizer or fresh manure into the planting hole, which can burn sensitive new roots and cause water retention issues.
- Using a planting hole with smooth, glazed sides in clay soils, which effectively creates a sump and inhibits root penetration outward.
- Misconception: All plants need the same amount of water. Correction: Water needs vary by species, soil type, and weather; overwatering can be as harmful as underwatering.
- Misconception: Organic fertilisers are always better than synthetic ones. Correction: Both have pros and cons; choice depends on soil conditions, plant needs, and environmental impact.
- Misconception: Pruning is only for shaping plants. Correction: Pruning also promotes health, removes dead or diseased wood, and encourages flowering or fruiting.
