Many gardeners now welcome wildflowers in their lawn as a way to add interest and support wildlife. However, if you still strive for a manicured lawn containing only certain grass species, you may view other plants as weeds and wish to remove them.
Lawn weeds tend to be tough, perennial, low-growing plants that are tolerant of regular mowing and foot traffic. They often have creeping, rooting stems or readily produce seed, and are quick to colonise bare ground where grass growth is patchy. Common lawn weeds include: Clovers Coarse grasses, such as couch grass Creeping buttercup Creeping cinquefoil Daisies Dandelion Dove’s foot cranesbill Field wood-rush Plantain Sheep’s sorrel Speedwell Yarrow Algae, lichens, liverworts and mosses are also commonly found in lawns, particularly those in shade or on poorly drained soil.
The term ‘weed’ describes a plant that is growing where it isn’t wanted. Weeds usually thrive in average garden conditions, reproducing and spreading easily. It is up to you to decide what you call a weed and what you choose to retain or remove.
No – most lawn weeds are UK native wildflowers that support a wide range of garden wildlife. Dandelions, for example, are a valuable early source of nectar for bees, creeping buttercup has pollinator-friendly flowers that attract butterflies and hoverflies, and yarrow is a food plant for 42 different species of moth. Many lawn weeds have attractive flowers and foliage, and allowing a variety to grow in your lawn can create a colourful tapestry. Some, like clovers, are more drought tolerant than lawn grasses, meaning they stay green throughout long, dry summers. And, as species-rich lawns generally don’t require frequent mowing, or any feeding or watering, they are a low maintenance and low input option. Many gardeners are now deliberately choosing clover or wildflower lawns over all-grass options and adopting practises like differential mowing, No Mow May and Let it Bloom June to encourage plant diversity in their lawns and the benefits it brings.
No – although it can take patience and persistence to remove lawn weeds, non-chemical methods are effective, so there is no need to use a weedkiller. Selective lawn weedkillers can cause damage to other plants when contaminated lawn clippings are added to compost and used as a mulch. See our page on weedkiller damage for information on the risks involved in using lawn weedkillers.
Lawn weedkillers and fertilisers are often sold together as ‘weed and feed’ products and offered as part of routine maintenance by lawn care companies. Not only do these products reduce lawn biodiversity, but they are often unnecessary, as most lawns do not need regular feeding to stay green and healthy. Weedkillers and fertilisers also have big environmental impacts. So, if you need to control weeds, stick to the non-chemical methods described above, and if your lawn is low in vigour and needs feeding, choose a proprietary fertiliser and apply it carefully.
