GreenThumb Weeds


What are lawn weeds and why are they a problem?

Lawn weeds are unwanted plants that grow alongside your desired grass. They can quickly take over your lawn, competing for nutrients, water, and sunlight. Not only do they ruin the appearance of your garden, but they also pose a threat to the health of your grass.

Preventing Lawn Weeds

When it comes to maintaining a beautiful and healthy lawn, one of the biggest challenges is dealing with weeds. Fortunately, there are several effective practices you can implement to prevent weed growth and maintain a weed-free lawn.

Proper lawn maintenance is crucial in preventing weed growth. Regular mowing at the appropriate height helps to keep your grass healthy and dense, leaving less room for weeds to take root. It is recommended to mow your lawn at a height of about 2-3 inches, as this promotes stronger root growth and shades the soil, making it harder for weeds to germinate.

Another important factor in preventing lawn weeds is choosing the right grass type for your region. Different grass species have varying levels of resistance to weeds, so selecting a grass type that is well-suited to your climate and soil conditions can make a significant difference, consulting with your local GreenThumb branch will help you make an informed decision on the most suitable grass seed for your lawn.

Additionally, the proper use of fertilisers and herbicides can play a crucial role in preventing weed growth, which is where GreenThumb come in.

Do GreenThumb's treatments deal with my weeds?

Of course, and generally you can expect over half of your weeds to die-off in any one treatment. So after three or four treatments, most of your weeds will have disappeared.

However, it is a never-ending battle to keep your lawn weed-free as seeds lie dormant and others are blown in from neighbouring locations, ongoing treatments are always necessary.

There are numerous types of lawn weeds that you may encounter in your garden. Below is a selection of the most common lawn weeds, although your local operative will be able to advise you as and when they carry out a lawn analysis if you have anything more 'exotic'.
