    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating the correct stage of seedling development for pricking out (first true leaves present).
    • Award credit for safely loosening the growing medium around seedlings with a dibber or widger without damaging the delicate roots.
    • Award credit for holding seedlings only by their seed leaves (cotyledons) to avoid stem crushing and disease entry.
    • Award credit for making an appropriately sized hole in the fresh compost with a dibber, ensuring the seedling’s roots are fully accommodated without curling.
    • Award credit for firming the compost gently around the transplanted seedling and watering in lightly with a fine rose to settle the roots.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡When being assessed on practical performance, clearly narrate each step as you carry it out to demonstrate underpinning knowledge—for example, explain why you are handling by the seed leaves.
    • 💡Prepare a detailed witness statement or photographic portfolio showing the sequence from seed tray preparation, through pricking out, to aftercare; annotate to highlight key techniques and health and safety considerations.
    • 💡Ensure your work area is clean and tidy before starting, and use clean, labelled pots or trays to meet hygiene standards, as assessors will check for cross-contamination risks.
    • 💡Check that your seedlings show no signs of disease or pests before pricking out, and demonstrate how you would dispose of any waste material appropriately as part of the assessment.
    • 💡**Prioritise Health and Safety:** Examiners will rigorously assess your adherence to health and safety protocols during practical tasks. Always wear appropriate PPE, handle tools correctly, and demonstrate awareness of your surroundings. Explain your safety considerations as you work.
    • 💡**Demonstrate Understanding, Not Just Action:** When performing practical tasks, articulate *why* you are doing each step. For example, when potting, explain why you firm the compost gently or why you leave a watering space. This shows a deeper understanding beyond mere rote memorisation.
    • 💡**Precision and Identification:** Be precise with your terminology. When identifying tools, plants, or soil types, use correct names. During practical tasks, demonstrate neatness and accuracy, such as making clean cuts when pruning or sowing seeds at the correct depth and spacing. Attention to detail significantly impacts your marks.

    Common Mistakes

    Common errors to avoid in your coursework

    • Attempting to prick out seedlings too early when they only have seed leaves, leading to poor survival due to insufficient root development.
    • Pulling seedlings by their stems instead of holding seed leaves, causing irreversible crushing damage to the vascular tissue.
    • Forgetting to water the seedlings thoroughly both before and after transplanting, which causes root desiccation and transplant shock.
    • Planting seedlings at the wrong depth—either burying the stem too deep (encouraging rot) or leaving roots exposed (causing drying out).
    • Using poor-quality, clumpy compost that contains large particles and uncomposted material, which hinders fine root establishment.
    • **Misconception:** All plants need the same amount of water, and more is always better. **Correction:** Watering requirements vary significantly based on plant species, soil type, pot size, and environmental conditions. Overwatering can be as detrimental as under-watering, leading to root rot and nutrient leaching. Always check soil moisture levels before watering.
    • **Misconception:** Any soil from the garden can be used for potting plants in containers. **Correction:** Garden soil is often too heavy, lacks sufficient drainage, and may contain pests, diseases, or weed seeds unsuitable for containers. Potting compost is specifically formulated to provide the correct balance of nutrients, aeration, and drainage for plants in confined spaces.
    • **Misconception:** Pruning is simply about cutting off any unwanted parts of a plant. **Correction:** Pruning is a skilled horticultural practice with specific objectives, such as promoting plant health, encouraging flowering or fruiting, maintaining shape, or removing diseased/damaged wood. Incorrect pruning can harm the plant, so understanding the 'why' and 'when' is crucial, not just the 'how'.
