We do a lot of our weed control by hand and try to minimise the usage of chemicals as much as possible.
We use a residual herbicide on many of our freshly potted plants to help prevent weed seed germination. However we don't apply this to all of our stock as some plants are susceptible to chemical damage.
We also use a contact herbicide on the hard standing around the nursery. Before using any of these chemicals its important that we familiarise ourselves with the health and safety precautions.
