Polythene sheets. Enough to cover the entire area
that is being worked, including floors, walls,
windows and any furniture that may be in the area.
Wet / dry vacuum cleaner, cloths and mops to clean
up the area afterwards.
Access equipment, e.g. a cherry picker or scaffold
Sprayer with a coarse-grade nozzle or watering
machine with a long lance and spray nozzle.
Plant cleaning solution. This must be suitable
for the job. Some acidic cleaners may damage
floors, walls and fixtures, so these must be thoroughly
Warning cones, barrier tapes and sign boards.
Personal Protective Equipment (PPE), e.g. coveralls,
visor, face mask, gloves, hard hat (for working
at heights), waterproof clothing, boots / shoes
with non-slip soles, restraining harness if working
from height where no other method of safe access
Risk assessments should be completed and checked
before work commences.
Trees such as Ficus should be shaken to remove
any loose leaves.
Trees should be cleaned using a sprayer or watering
machine with a high pressure nozzle. When using
a sprayer, use a coarse spray quality. Avoid generating
a fine mist, aim for large droplets that will
penetrate the canopy of the plant. Ensure that
the whole foliage is cleaned, including the underside
of leaves and the centre of the tree’s canopy.
When the job is finished, the site must be cleaned
and cleared. Proper waste disposal arrangements
must be in place to deal with surplus cleaning
solutions and contaminated protective materials.
Cleaning products. Some plant cleaning products
are more aggressive than others. If the tree only
needs light cleaning, a soapy detergent-based
product (e.g. Rentokil Plant Cleaner) will be
suitable. More heavily soiled plants may need
something stronger, such as a citric-acid based
product. However, additional protective
equipment and materials may be required.
