As well as choosing products that will actually kill the weeds you have, it is worth remembering that there are different formulations. For example, ready-to-use spray guns are ideal for killing a few weeds in a patio, whereas a bottle of concentrate that you mix up is more economical for a large border. Here we explain the choices.

It is best to follow the advice given on the packet. Many weeds respond best to treatment when they are in full growth, and always apply on a calm day to prevent the spray drifting on to plant you want to keep.

Health and Safety Executive: home garden chemicals
Always follow the dosing, application and health-and-safety instructions given on the label of the product concerned.
Although it is not a legal requirement to wear protective clothing when handling and using amateur/home pesticides, the RHS recommends wearing gloves, Wellington boots and other protective clothing as a sensible precaution.
Problems may arise when the instructions on the product are not followed and you may get weedkiller damage on desirable plants. Always read the label first for the best advice to help you get the most effective control.
