Water hyacinth removal by hand or machine is a practical
control method often used for small areas or when plant
numbers are low. Physical removal is most effective for
small infestations and should be made before flowering
and seed set in October.
Mechanical control of water hyacinth can help take
advantage of flooding or water flushes that deposit water
hyacinth in dams, lagoons and calm water areas of rivers
and creeks. When using this approach it is essential water
hyacinth is removed before its rapid growth commences.
Water hyacinth that is deposited or left on moist banks
can survive for long periods out of the water. To help
prevent the reintroduction of water hyacinth into the
watercourse, it is essential it is moved from the waters
edge and preferably burnt.
