Three tips when buying weed control

  • Contact herbicides kill everything they come into contact with – often within hours. However, it doesn’t kill the actual root system. This variety is good for various nettles and other annual weeds.

  • Systemic herbicides are absorbed by the plant and travel right down to its roots. This prevents the weeds from growing and spreading, but it often takes a couple of weeks before the effect can be seen. These herbicides are good for perennial weed varieties that spread both via seeds and roots, such as thistles and dandelions.

There are also weed killers that combine both of these varieties.

If you have pets with free access to the garden, you should use non-toxic herbicides. They are also kind to wild animals and insects, which could otherwise be harmed.

Also choose as mild a treatment as possible if you’re going to treat areas where you grow fruit, vegetables or sensitive plants. In these places it may be better to remove the weeds manually with a weed picker or weed burner.

Choose a herbicide that treats the area effectively.

  • A pressure sprayer is good for weeds in larger areas, as it spreads quickly and efficiently.

  • Sprays or gels are suitable in places where you want to treat specific weeds without running the risk of damaging the surrounding plants. Gels are also effective against weeds that spread through the roots – simply apply the gel to the stem.

  • Herbicides that are diluted in water are good when you want to treat the entire garden in one go when watering.

  • Vinegar weed killer is both a fast and powerful contact herbicide – and it’s also biodegradable. The vinegar is effective against weeds that multiply via seeds, but doesn’t work as well on weeds that spread through the roots. However, the vinegar shouldn’t be used on flowerbeds, as it makes the soil acidic. But it’s still very effective on gravel and between paving stones.

To make sure you have everything you need to manage the weeds, maybe you should invest in a weeder tool as well?
