Topic Synopsis
This subtopic addresses the essential horticultural practice of lifting established herbaceous perennials from the ground, dividing the root clumps into smaller viable sections, and replanting them. It covers timing, technique, aftercare, and the benefits for plant health and propagation.
Key Concepts & Core Principles
- Plant identification: Learn to recognise common garden plants, including annuals, perennials, shrubs, and trees, using features like leaf shape, flower colour, and growth habit.
- Soil preparation and planting: Understand how to prepare soil by digging, removing weeds, and adding organic matter, then plant correctly at the right depth and spacing.
- Safe use of tools and equipment: Know how to select, use, and maintain basic tools like spades, forks, secateurs, and watering cans, following health and safety guidelines.
- Plant care: Master watering, feeding with fertilisers, pruning, and pest/disease control to promote healthy growth and flowering.
- Health and safety: Apply risk assessments, use personal protective equipment (PPE), and handle chemicals safely to prevent accidents in the garden.
Exam Tips & Revision Strategies
- Check the plant's condition before lifting; avoid plants showing signs of disease or pest infestation.
- Water the plant thoroughly a day before lifting to ease division and reduce transplant shock.
- Prepare the planting site in advance so divisions can be replanted quickly.
- Document each stage with labelled photographs or notes for your portfolio evidence.
Common Misconceptions & Mistakes to Avoid
- Dividing plants at the wrong time of year, such as during active flowering or in drought conditions.
- Using blunt tools that crush rather than cut through roots.
- Allowing divisions to dry out before replanting.
- Planting divisions too deeply, burying the crown, or leaving roots exposed.
Examiner Marking Points
- Award credit for selecting the correct tools (e.g., border fork, hand fork, sharp knife) and wearing appropriate PPE.
- Candidate demonstrates safe lifting posture and technique, minimising rootball disturbance.
- Each division must contain at least one healthy shoot and a portion of the root system.
- Divisions are replanted with the crown at soil level, firmed in, and watered immediately.
- The candidate tidies the work area and disposes of old or damaged plant material appropriately.
