Lawn weeds are any invasive plant that’s competing with your lawn for space and nutrients. Things like clovers, daisies, and dandelions are most common along with a long list of other weeds but preventing them is much better than trying to tackle a lawn full a weeds that have not been treated in years.
Removing weeds promptly is the key to effective weed control especially if you have a large area and cover. This might be something as simple as maintaining a good annual lawn care plan which included applying a good lawn weed and feed. But how do you know if you really have a weed problem as some are very small and can blend in with the lawn?
Spotting signs of weeds in your lawn
You look for the signs. Your grass might start to take a patchy appearance with uneven growth. There might be certain areas across your lawn that have a different texture than the rest. If you see flowers growing in your grass, that’s a pretty clear sign. If certain patches remain green during a drought, it could be indicative of weeds that are performing better than the rest of your lawn and of course, there are those large broadleaf weeds such as dandelions which are easy to spot.
If you notice the signs, it’s time to take action. Weeds spread by seed or by creeping stems and if you have any area of grass that sparse, they will quickly take over. This is one of the reasons you ideally want to scarify your lawn in Autumn as the process often leaves bare patches on your lawn so you want to scarify with weed germination and growth is at it lowest.
So, it’s time to decide whether you want to use natural controls first which basically means removing weeds by hand with a weed puller or skip straight ahead to the chemical weed killers which is the best choice for smaller but large infestation of weeds. If you use good natural controls you might not need chemical controls. But some weeds are really hard to kill, so it never hurts to know all of your options.
Natural controls to control weeds in lawns
You can try non-chemical options to get rid of your weed problem before you turn into commercial weed killers.
The first step in maintaining a good lawn and doing away with weeds is to give your lawn food, and to aerate and scarify the lawn every year. If you see rosette type weeds like daisies or dandelions you can remove those using a hand fork or weeding tools. You can also rake over your lawn and mow it on a regular basis to discourage creeping weeds from getting too big. In the wintertime, apply some lime to your soil to deter winter-based weeds like field wood rush.

Using weed killers to control weeds in lawns
You could do all of those natural controls and still have a problem with weeds now and again in which case commercial weed killers are best.
Lawn weed killers can be used anywhere on your lawn that weeds have already established themselves. It’s important that you check the label to make sure that it will work on the type of weeds you see manifesting in your garden.
When you apply a lawn weed killer do so in the spring and the summer as weeds are the two times in the year when they will grow most voraciously. Always read the instructions before you start and follow them explicitly to get effective results.

Types of weedkillers to consider
Pay attention to the product you purchase and how it is applied. When you go to the garden centre or the nursery, or even online you can find lawn weed killers that are granules you scatter on the surface, we recommend using a lawn spreader to apply as it can burn the lots leaving dead patches. Spot treatment sprays are ideal for targeting broadleaf weeds while weed killers that you have to add to your watering can which you then apply across the surface of larger areas of lawn are ideal. Pick one that you like best and feel comfortable using.
How many treatments does it take to kill weeds in a lawn
Most weeds in your lawn can be effectively done away with using a single treatment but there might be some sticklers that require two or three applications on an average of 5 weeks in circles before they are completely gone. So if you have a few stragglers sticking around after your first application, don’t worry.
When reviewing different product if you see one that is a weed killer and moss killer, only use it if you have a problem with moss as well as you can keep just weed and feed type products. The only exception to this is if you have a lawn that is prone to moss as it will help control the moss too.
If you have a new lawn, be advised that it can be severely damaged by weed killers if you apply it to the lawn within six months of laying new turf. To that end, it’s important that you allow your new lawn to grow in for at least 6 months before you start tackling your weed problem. Weeds are not usually a problem at first but if you do we recommend using manual weeds tools.
