you tell me the best way to kill off liverwort which is becoming
a nuisance around palms, cycads and on the soil surface in many
parts of my garden?
are many products on the market that claim to control liverworts
and some gardeners claim a solution of vinegar also does the job.
While most of these products
do work quite well, their effectiveness can vary depending on the
local conditions, how well you apply the product and how severe
the liverwort problem is.
However, my friends at
Totara Waters Subtropical Garden in Whenuapai have started using
the coconut oil-based weedkiller Hitman and find it very effective
at quickly getting rid of liverworts. Within a few hours of being
sprayed, the liverwort changes colour and starts to die off.
As with most of these
types of products, you need to be careful using it - they all work
by breaking down the cell walls of whatever plant material they
come in contact with, so make sure not to get the spray on desirable
