Lawn Weed Control in Cardiff & South Wales

Weeds can be quick to colonise large parts of your lawn and spoil its once-lovely appearance. Off-the-shelf weed killers may seem effective at first, but unless you address the conditions that allowed for weed growth in the first place, those weeds will soon grow back!

Here at Lawn & Weed Expert, we have many years’ experience providing elite, lasting lawn weed control across Cardiff and the wider South Wales area. Get in touch today for a FREE weed survey.
Our lawn weed control service doesn’t just treat the visible part of the weed – it also tackles the conditions that promote weed growth. As experts in our field, we can devise a weed control plan for your garden that goes on working where other treatments fail, saving you a lot of time and money in the long run.
Weeds are approximately 70% water and will usually decompose completely within 14 days of a Lawn & Weed Expert treatment.

Herbicides are usually best applied during periods of vigorous grass growth – such as spring, summer and late autumn – when weeds are growing as well.

How to control weeds in lawn

If you’re looking for tips and advice on how you can control weeds in your lawn, Lawn & Weed Expert are more than happy to share our expert knowledge!
When it comes to lawn weed control and killing weeds in your lawn without harming your grass, the best time to apply weed killer is when the weeds are in their 'fast-growing stage'. Like most plants, typical garden weeds grow the most during spring and into summer. That means the best time to apply weed killer is between May and June.
If you’re planning on treating your lawn weeds yourself, there are a few questions you need to ask yourself before you start applying weed killer.
Before applying weed killer, you should make sure the lawn has been properly fertilised. This helps to ensure that the grass that remains has plenty of nutrients to continue growing strong & healthy. Give the fertiliser a couple of days to kick in before you apply weedkiller.
Weed killer works best on soil that's slightly damp, but not wet. If it's just rained, or is due to rain over the next day or two, postpone your weed killer application for a couple of days. Excessive water will dilute your weed killer, making it less effective. Similarly, avoid applying weed killer if it's freezing cold or scorching hot. You ideally want mild weather conditions to apply weed killer.
Applying weed killer to a freshly cut lawn is not ideal. It's best to apply weed killer to weeds that have had a chance to start growing back, so that more the plant comes into contact with the herbicides. We would recommend leaving your lawn for 2 to 3 days after cutting before applying an herbicide. Following the application, you should not cut your lawn for at least a week. This gives the weed killer chance to penetrate the soil properly without being disturbed.

Applying weed killer can be a lot more complicated than people think! If you’re not confident in weed killer application and are looking for professional assistance, we’re always happy to help!
