AIMS

  • Develop the ability to source information on plant propagation, through an awareness of industry terminology and information sources.
  • Plan the propagation of different plant species from seeds, using different seed propagation methods.
  • Plan the propagation of different types of plants from cuttings, using different cutting propagation methods.
  • Plan the propagation of various types of plants using a range of propagation techniques, excluding cuttings and seed.
  • Determine the necessary facilities, including materials and equipment, required for propagation of different types of plants.
  • Determine a procedure to minimise plant losses during propagation.
  • Determine the management practices of significance to the commercial viability of a propagation nursery.
  • Design a propagation plan for the production of a plant.
  • WHAT YOU WILL DO IN THIS COURSE

    Here are some examples of what you may do:

    • Test soils to determine characteristics which would be valuable to management of any given soil in a horticultural situation
    • Identify sandy loam, silty loam, and clay loam soils by feel; and pH testing by soil indicator; and relate to plant selection
    • Identify and sow a range of different types of seeds, in different situations, in a way that will optimise successful propagation.
    • Propagate a range of plants using different vegetative propagation techniques
    • Pot up and provide after care for a range of propagated seedlings and cuttings.
    • Plant a range of (different types) plant material.
    • Maintain the desired growth type and habit for a range of plants.
    • Identify significant woody plants including: Trees; Shrubs; Groundcover; & Conifers
    • Identify a range of significant plant problems including pests, diseases and others.
    • Identify a range of non woody and indoor plants of horticultural significance.
    • Conduct a risk assessment of a horticultural workplace to determine safe working practices and select appropriate personal safety clothing and equipment.

     

    PROPAGATION TIP

    Preventing pests and diseases in the propagation area

    It doesn’t matter if you are a backyard propagator, or working as a propagator in a full scale production nursery, good hygiene and prevention are generally the best ways to reduce the occurrence of pests and diseases during propagation.

    Pests and diseases can spread many different ways including:

    • Dipping healthy cuttings in hormone or water in which diseased material has been dipped.
    • Through irrigation (eg. from contaminated water sources) or rain water (dripping off structures or diseased plants, or by splashing up soil).
    • Soil-borne diseases on the hose if it's dropped on the ground.
    • Soil on the bottom of pots/trays.
    • On tools, clothes, shoes and workers hands.
    • Contaminated soil mixes or pots.
    • Infected plant material.

    Some ways to help reduce pest and disease problems while propagating plants, include:

    • Using sterilised propagation and potting media. These can be purchased from some garden nurseries and garden supplies, or specialist potting mix companies. Alternatively if you can’t obtain sterilised mixes, then use media made from soilless components, such as peat moss, and coarse washed river sand.
    • Increasing the spacing between plants can increase ventilation, reducing the likelihood of diseases occurring and spreading.
    • Segregate clean and treated pots. Never store clean pots on the ground. Clean all used containers before reuse removing as much media and plant debris as possible. Ideally they should then be dipped in a sterilant (eg. Bleach or ammonia or ammonia solutions).
    • Use good quality plant material for propagation (vigorous growth, free of obvious pest and disease problems).
    • Disinfect material used for cutting propagation before using in a 2% sodium hypochlorite solution (bleach) for one minute then rinsed the plant material in clean disinfected water to remove the bleach.
    • Take cuttings from the top of plants - this is the cleanest part.
    • Clean any tools thoroughly before using, and ideally between working on different plants. Dip cutting tools in a disinfectant such as methylated spirits or a 5% bleach solution.
    • Place clean plant material only on cleaned/sterilised benches.
    • Don't handle soil or plants unless hands have been washed with hot water and soap, or a suitable disinfectant such as Savlon or Dettol, or use disposable gloves.
    • Avoid splashing water near sterilised soil, pots, benches, etc.
    • Pots should always be placed on well drained surfaces (preferably concrete, screenings or raised benches.
    • Hang hoses on a hook...don't lie them on the ground, particularly nozzles.
    • Place any plants which you suspect to be diseased in an isolated area.
    • Apply control methods to pests and diseases as soon as they are detected to prevent their spread.
