KEEP IT CLEAN
One of the first things for anyone to learn when they work in a nursery is the importance of cleanliness.
Plants like people can become infected by disease and die; and sick or dead plants are a financial loss to the nursery. Nursery hands need to understand both the importance of avoiding disease, and the ways a nursery minimises disease issues.
Diseases among young plants are potentially a catastrophe. It is possible to grow plants for years, paying little attention to disease control and have little trouble. However, if you do get a disease problem it can become epidemic and destroy a large proportion of your stock in a very short space of time (even a day or two).
Disease can spread many different ways:
- By dipping cuttings in hormone or water
- Through irrigation or rain water
- Soil 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, etc.
A major concept in avoiding disease is recognising where they may originate from and stopping them from ever being introduced into the nursery. There are many prophylactic measures that can be adopted.
A system developed by the University of California (U.C.) is often used to set guidelines for managing disease (summarised as follows):
- Use a U.C. system type Soil Mix (explained in the course).
- Good drainage must be provided. This allows for a proper balance between oxygen and water to be maintained in the root zone.
- Leach the soil (to remove salt build ups and disease organisms from the soil).
- Sterilise the soil before use (making it free of disease and weed seeds).
- Use good quality water (free of disease/unwanted chemicals).
- Undertake frequent light fertilising (to maintain nutrient levels and replace any nutrient lost by leaching).
- Disease free plant material.
- Clean out containers (pots, trays, etc. are thoroughly washed out using a chemical such as bleach, Biogram, Jeyes Fluid, TCP or Detol to kill disease). The agent is most often diluted with water, but always read instructions before use.
- Adhere to strict sanitation practices (thorough cleanliness is practiced; benches are washed with chemicals, tools dipped, workers walk through foot wash to clean boots, wash hands before work, etc).
